longbridge-python-sdk	LongPort Python SDK — 行情、持仓、自选、估值指标(PE/PB/股息率/EPS/BPS)、资金流向。支持港股/美股/A股。bashrc已有LONGPORT_*变量，可直接Config.from_env()。

LongPort Python SDK Usage

Use this skill to interact with LongPort via Python instead of the CLI. The SDK requires LONGPORT_ environment variables, while the user's bashrc uses LONGBRIDGE_.

⚠️ CRITICAL: Mainland China Access (602315 Bypass)

LongPort API rejects all trading requests from Mainland China IPs with error 602315. The SDK auto-detects CN via HTTP probe to geotest.lbkrs.com and routes to *.longbridge.cn (Aliyun Shenzhen) which has the geo-block.

The only known working bypass from CN servers (verified 2026-07-09, order ID 1259547163696824320):

import os

# 1. Force SDK to use international endpoint (NOT mainland CN probe)
os.environ['LONGBRIDGE_REGION'] = 'ap'  # or 'us'

# 2. Load LONGPORT_* credentials from bashrc (same as before)
# ... existing bashrc-loading code ...

from longport import openapi
cfg = openapi.Config.from_env()
trade_ctx = openapi.TradeContext(config=cfg)

# 3. Wrap the entire Python process with proxychains4 at the OS level:
#    proxychains4 -f ~/.proxychains/proxychains.conf python3 your_script.py

Critical: must run via proxychains (Rust binary needs OS-level hook):

LONGBRIDGE_REGION=ap \
proxychains4 -f ~/.proxychains/proxychains.conf \
  python3 ~/.hermes/scripts/us_intraday_monitor.py

Why all three pieces are required:

• Without LONGBRIDGE_REGION=ap: SDK probes geotest.lbkrs.com → 200 from CN → assumes mainland → uses .cn → 602315
• Without proxychains: Python's HTTPS connections (via Rust SDK) bypass HTTP_PROXY env var
• Without HK Clash node: Even with proxychains, CN nodes get geo-blocked at the gateway

Setup requirements (same as longbridge-cli skill):

• Clash Mihomo running with mixed-port: 7890 (HTTP proxy)
• Clash GLOBAL selector on 🇭🇰 [Lv2] 香港 01 (or 02/03) — NOT mainland China
• ~/.proxychains/proxychains.conf with http 127.0.0.1 7890 in [ProxyList]
• DO NOT use WireGuard — Ubuntu WG shutdown is unreliable, leaves broken routes

Verify setup before running cron jobs:

# Confirm Clash routes via HK
proxychains4 -f ~/.proxychains/proxychains.conf curl -s --max-time 8 https://api.ipify.org
# Should return HK IP (e.g. 154.83.87.231)

For cron jobs that submit orders (e.g. us_intraday_monitor.py, hk_intraday_monitor.py): The script command must include proxychains4 wrapper. Update cron script field from us_intraday_monitor.py to:

# Option A: wrap entire script
proxychains4 -f ~/.proxychains/proxychains.conf python3 /home/openclaw/.hermes/scripts/us_intraday_monitor.py

Or set LONGBRIDGE_REGION=ap in the script's environment directly (more reliable than cron env vars).

When to use

• User asks for holdings, quotes, or account info via Python.
• CLI longbridge command fails (e.g., token issues, missing args).

Setup

1. Install SDK: pip3 install longbridge (package name on PyPI is longbridge, but import is from longport import openapi). Do NOT pip install longport — that's a different/empty package.
2. ~/.bashrc now has BOTH sets of variables (added 2026-06-01):

   # CLI uses these
   export LONGBRIDGE_APP_KEY=<key>
   export LONGBRIDGE_APP_SECRET=<secret>
   export LONGBRIDGE_ACCESS_TOKEN=<token>
   
   # Python SDK uses these (same values, references LONGBRIDGE_ vars)
   export LONGPORT_APP_KEY=${LONGBRIDGE_APP_KEY}
   export LONGPORT_APP_SECRET=${LONGBRIDGE_APP_SECRET}
   export LONGPORT_ACCESS_TOKEN=${LONGBRIDGE_ACCESS_TOKEN}
   

3. With both sets in bashrc, Config.from_env() works directly without manual mapping.

Usage Steps

1. Connect (LONGPORT_* now in bashrc):

   from longport import openapi
   cfg = openapi.Config.from_env()  # Reads LONGPORT_* vars directly
   ctx = openapi.QuoteContext(config=cfg)
   trade_ctx = openapi.TradeContext(config=cfg)
   

Usage

• Holdings: resp = ctx.stock_positions() → iterate resp.channels[0].positions
• Balance: ctx.account_balance()
• Orders: ctx.today_orders()

Extended API (discovered via testing)

Watchlist

resp = ctx.watchlist()  # Returns list[WatchlistGroup]
for group in resp:
    print(f'Group: {group.name}')  # e.g. "收息", "月派", "all"
    for sec in group.securities:
        print(f'  {sec.symbol}: {sec.name} @ {sec.watched_price}')

WatchlistGroup fields: name, securities (list) WatchlistSecurity fields: symbol, market, name, watched_price (Optional), watched_at (ISO string) Special groups: all (auto-generated, all securities), us/hk (market-based auto-groups)

Static Info (EPS, BPS, shares)

resp = ctx.static_info(['O.US', '823.HK'])
for info in resp:
    # Key fields: symbol, name_en, name_cn, currency, exchange, board
    # Valuation: eps, eps_ttm, bps, dividend_yield
    # Shares: total_shares, circulating_shares, hk_shares
    # Other: lot_size, stock_derivatives

Calc Indexes (PE, PB, Market Cap, etc.)

from longport.openapi import CalcIndex

indexes = [
    CalcIndex.PeTtmRatio,       # PE TTM
    CalcIndex.PbRatio,          # PB
    CalcIndex.DividendRatioTtm, # Dividend yield TTM
    CalcIndex.TotalMarketValue, # Total market cap
    CalcIndex.TurnoverRate,     # Turnover rate
    CalcIndex.VolumeRatio,      # Volume ratio
    CalcIndex.ChangeRate,       # Change %
]
resp = ctx.calc_indexes(['O.US'], indexes)
for item in resp:
    print(f'{item.symbol}: PE={item.pe_ttm_ratio}, PB={item.pb_ratio}')

Available CalcIndex values: Amplitude, BalancePoint, CallPrice, CapitalFlow, ChangeRate, ChangeValue, ConversionRatio, Delta, DividendRatioTtm, EffectiveLeverage, ExpiryDate, FiveDayChangeRate, FiveMinutesChangeRate, Gamma, HalfYearChangeRate, ImpliedVolatility, ItmOtm, LastDone, LeverageRatio, LowerStrikePrice, OpenInterest, OutstandingQty, OutstandingRatio, PbRatio, PeTtmRatio, Premium, Rho, StrikePrice, TenDayChangeRate, Theta, ToCallPrice, TotalMarketValue, Turnover, TurnoverRate, UpperStrikePrice, Vega, Volume, VolumeRatio, WarrantDelta, YtdChangeRate

Candlesticks (with AdjustType)

from longport.openapi import Period, AdjustType

candles = ctx.candlesticks('O.US', Period.Day, 365, AdjustType.ForwardAdjust)
# Returns: timestamp, open, high, low, close, volume, turnover

⚠️ PITFALL: candlesticks() requires adjust_type parameter — will fail with "missing 1 required positional argument: 'adjust_type'" without it. Always pass AdjustType.ForwardAdjust (前复权) or AdjustType.NoAdjust.

Fundamental Data (calc_indexes + static_info)

calc_indexes — PE, PB, 股息率, 市值等

from longport.openapi import CalcIndex

indexes = [
    CalcIndex.PeTtmRatio,          # PE TTM
    CalcIndex.PbRatio,             # PB
    CalcIndex.DividendRatioTtm,    # 股息率 TTM (%)
    CalcIndex.TotalMarketValue,    # 总市值 (货币单位)
    CalcIndex.TurnoverRate,        # 换手率 (%)
    CalcIndex.VolumeRatio,         # 量比
    CalcIndex.ChangeRate,          # 涨跌幅 (%)
    CalcIndex.FiveDayChangeRate,   # 5日涨跌幅
    CalcIndex.TenDayChangeRate,    # 10日涨跌幅
    CalcIndex.HalfYearChangeRate,  # 半年涨跌幅
    CalcIndex.YtdChangeRate,       # 年初至今涨跌幅
]

resp = ctx.calc_indexes(['O.US', '823.HK'], indexes)
for item in resp:
    print(f'{item.symbol}: PE={item.pe_ttm_ratio}, PB={item.pb_ratio}, 股息率={item.dividend_ratio_ttm}%')

static_info — EPS, 每股净资产, 股本

resp = ctx.static_info(['O.US', '823.HK'])
for info in resp:
    print(f'{info.symbol}: EPS_TTM={info.eps_ttm}, BPS={info.bps}, 总股本={info.total_shares}')

static_info 字段: symbol, name_cn, name_en, name_hk, currency, lot_size, eps, eps_ttm, bps, dividend_yield, total_shares, circulating_shares, exchange, board

watchlist — 自选列表

resp = ctx.watchlist()
for group in resp:
    print(f'分组: {group.name} ({len(group.securities)}只)')
    for sec in group.securities:
        print(f'  {sec.symbol}: {sec.name} @ {sec.watched_price}')

特殊分组: all (全量), us/hk (按市场自动分组), 用户自建分组 (如"收息", "月派")

Order Placement (Trading)

Trading requires LONGBRIDGE_TRADE_ENABLED=true in bashrc. Use execute_code for all order operations (not terminal).

Submit Limit Order

os.environ["LONGBRIDGE_TRADE_ENABLED"] = "true"

resp = ctx.submit_order(
    symbol="RGTI.US",
    order_type=openapi.OrderType.LO,              # Limit Order
    side=openapi.OrderSide.Sell,                   # or .Buy
    submitted_quantity=15,
    time_in_force=openapi.TimeInForceType.Day,     # or .GoodTilCanceled
    submitted_price=21.00,
    outside_rth=openapi.OutsideRTH.AnyTime,        # optional: pre/post market
)
print(f"Order ID: {resp.order_id}")

Key Enums

• OrderType: LO (Limit), MO (Market), ALO (At Limit Open), ELO (Extended Limit)
• OrderSide: Buy, Sell
• TimeInForceType: Day, GoodTilCanceled, GoodTilDate, Unknown
• OutsideRTH: AnyTime (pre+regular+post), Overnight, RTHOnly, Unknown

Cancel / Query Orders

# Today's orders
orders = trade_ctx.today_orders()
for o in orders:
    print(f"{o.symbol} {o.side} {o.quantity}@{o.price} [{o.status}]")

# Cancel
trade_ctx.cancel_order(order_id)

Modify Existing Order (Cancel + Replace, 2026-07-08)

LongPort SDK has no replace_order / modify_order — must cancel old + submit new. Workflow:

# 1. Find old order ID
orders = trade_ctx.today_orders()
old_id = next(o.order_id for o in orders
              if 'RGTI' in o.symbol and o.status.name == 'New')

# 2. Cancel old
trade_ctx.cancel_order(old_id)

# 3. Submit new at desired price (LO, GTC)
new = trade_ctx.submit_order(
    symbol="RGTI.US",
    order_type=openapi.OrderType.LO,
    side=openapi.OrderSide.Sell,
    submitted_quantity=15,
    time_in_force=openapi.TimeInForceType.GoodTilCanceled,
    submitted_price=17.00,
    outside_rth=openapi.OutsideRTH.AnyTime,
)
print(f"New order ID: {new.order_id}")

Concurrency caveat: Brief gap between cancel and new-submit leaves position unprotected. For做T scenarios OK; for risk-managed positions use submit-before-cancel pattern (held in New queues). Verified 2026-07-08 with RGTI sell @ $21.40 → replaced with sell @ $17.00.

602315 Is Account-Level, Not IP-Level (2026-07-08 verified)

User confirmed LongBridge mobile app can place orders through a Hong Kong proxy, but the same user's desktop with US IP via Mihomo / proxychains4 gets 602315. Tested:

• Mihomo HTTP proxy 7890 → CLI direct (no proxy applied to SDK) → 602315
• proxychains4 + Mihomo → CLI/SDK goes through US IP → still 602315
• Same account on mobile with HK proxy → succeeds

Conclusion: 602315 is bound to the account's registered identity / region, not the IP exit. Pure IP-layer workarounds (proxychains, Mihomo proxy, even US-IP WireGuard on same account) all fail. Working paths:

• Mobile app on a connection that longport trusts (HK proxy verified, possibly other APAC)
• Different LongPort account with non-Mainland identity
• LongPort support ticket to escalate

Don't waste time: retrying SDK/CLI/proxychains on desktop when the user is geo-blocked. Switch to mobile or another tool.

602315 Asymmetry: Sell Passes, Buy Fails (2026-07-08 RGTI verified)

Real-world observed: Same network, same SDK config, same user — RGTI.US sell order @ $17.00 (GTC) succeeded, but RGTI.US buy order @ $15.50 (GTC) failed 602315. Likely some directional risk control on new positions; not stable to rely on. Implication: User cannot do做T接回 via SDK when geo-blocked; only sell-down. If client needs a buy-back order, use the long-port mobile app or enable VPN before buying. Don't waste cycles toggling SDK vs CLI — both share the same IP check.

WireGuard VPN Required for Geo-Block 602315 (2026-07-08)

Critical: Mihomo HTTP proxy (127.0.0.1:7890) does NOT resolve 602315 — that proxy is application-layer. LongPort API checks source IP and refuses Mainland China. WireGuard VPN (wg-trade on) assigns a real overseas IP at the network layer.

Approach	Layer	Resolves 602315
Mihomo proxy 127.0.0.1:7890	HTTP	❌
WireGuard VPN (wg-trade on)	IP	✅

wg-trade on    # enable VPN for trading
# do trades
wg-trade off   # restore direct route when done

VPN is required for ANY longport order from Mainland China IP, no exceptions. Both buy and sell fail with 602315 without VPN.

submit_order Signature

submit_order(symbol, order_type, side, submitted_quantity, time_in_force,
             submitted_price=None, trigger_price=None, limit_offset=None,
             trailing_amount=None, trailing_percent=None, expire_date=None,
             outside_rth=None, remark=None)

⚠️ time_in_force is required positional before optional submitted_price.

Quick Reference

Get Watchlist (with groups)

ctx = openapi.QuoteContext(config=cfg)
resp = ctx.watchlist()
for group in resp:
    print(f'{group.name}: {len(group.securities)} stocks')
    for sec in group.securities:
        print(f'  {sec.symbol}: {sec.name}')

Get Quotes

resp = ctx.quote(['O.US', '823.HK', 'JEPI.US'])
for q in resp:
    print(f'{q.symbol}: ${q.last_done}')

Get Holdings

trade_ctx = openapi.TradeContext(config=cfg)
positions = trade_ctx.stock_positions()
for ch in positions.channels:
    for pos in ch.positions:
        print(f'{pos.symbol}: {pos.quantity} @ {pos.cost_price}')

Common Pitfalls

Valuation Metrics (calc_indexes)

Get PE, PB, dividend yield, market cap via CalcIndex enum:

from longport.openapi import CalcIndex

indexes = [
    CalcIndex.PeTtmRatio,        # PE TTM
    CalcIndex.PbRatio,           # PB
    CalcIndex.DividendRatioTtm,  # 股息率 TTM (%)
    CalcIndex.TotalMarketValue,  # 总市值
    CalcIndex.TurnoverRate,      # 换手率
    CalcIndex.VolumeRatio,       # 量比
    CalcIndex.ChangeRate,        # 涨跌幅 (%)
]

resp = ctx.calc_indexes(['O.US', '823.HK'], indexes)
for item in resp:
    print(f'{item.symbol}: PE={item.pe_ttm_ratio}, PB={item.pb_ratio}, Yield={item.dividend_ratio_ttm}%')

Response fields (direct attributes, NOT a list):

• pe_ttm_ratio, pb_ratio, dividend_ratio_ttm
• total_market_value, turnover_rate, volume_ratio, change_rate

Static Info (EPS, BPS, Shares)

resp = ctx.static_info(['O.US'])
info = resp[0]
print(f'EPS TTM: {info.eps_ttm}')
print(f'BPS: {info.bps}')
print(f'Dividend Yield: {info.dividend_yield}%')
print(f'Total Shares: {info.total_shares}')
print(f'Currency: {info.currency}')

Fields: eps, eps_ttm, bps, dividend_yield, currency, total_shares, circulating_shares, name_en, name_cn, lot_size

Historical K-lines (Longer History)

candlesticks() is limited to ~1000 bars. For longer history use:

from longport.openapi import Period, AdjustType

# Parameters: symbol, period, adjust_type, backward, count
candles = ctx.history_candlesticks_by_offset(
    'AAPL.US',
    Period.Day,
    AdjustType.ForwardAdjust,  # 前复权
    False,                      # backward=True means older data
    1000,                       # max ~1000 per request
)

⚠️ Parameter order is different from candlesticks()!

• candlesticks(symbol, period, count, adjust_type)
• history_candlesticks_by_offset(symbol, period, adjust_type, backward, count)

Other Broker SDKs

📖 For comparison with 雪盈证券 (snbpy) and other Chinese/Asian broker SDKs, see references/broker-sdk-comparison.md.

Common Pitfalls

• Env Var Prefix: CLI uses LONGBRIDGE_, SDK uses LONGPORT_. Both are now in bashrc (LONGPORT_* references LONGBRIDGE_), so Config.from_env() works directly. If it fails, the fallback is to map manually from bashrc LONGBRIDGE_ values.
• Method Name: Use ctx.stock_positions(), NOT ctx.positions().
• Response Structure: stock_positions() returns a response object with channels list, then positions inside each channel.
• Decimal Type: total_market_value and some fields return decimal.Decimal, not float. Always wrap with float() for arithmetic.
• adjust_type Required: candlesticks() requires adjust_type parameter. Use AdjustType.ForwardAdjust for forward-adjusted prices.
• K-line Limit: Error code 301607 = "request too many klines". Max ~1000 per request. Use history_candlesticks_by_offset for pagination.
• calc_indexes Response: Returns SecurityCalcIndex objects with direct attributes (e.g., item.pe_ttm_ratio), NOT an indexes list.
• Token Expiration — two different codes:
  • 401003 "token expired": Token was valid but has reached its ~180-day expiry. All scripts using LongPort fail simultaneously. Fix: run bash ~/.hermes/scripts/update_longbridge_token.sh <new_token> to auto-update all locations and verify both CLI + SDK.
  • 401004 "token invalid": Token was truncated or never valid. Bashrc has a placeholder like m_eyJh...jb-k (with literal ...). Run the same script: bash ~/.hermes/scripts/update_longbridge_token.sh <new_token>. The script reads/bashrc-parsing approach shown below is a fallback for when the script is unavailable.

  import os, re
  env_vars = {}
  # Try .env first (authoritative), then bashrc
  for fpath in [os.path.expanduser('~/.env'), os.path.expanduser('~/.bashrc')]:
      if not os.path.exists(fpath):
          continue
      with open(fpath) as f:
          for line in f:
              line = line.strip()
              if line.startswith('export LONGBRIDGE_') or line.startswith('export LONGPORT_'):
                  parts = line.replace('export ', '').split('=', 1)
                  if len(parts) == 2 and '...' not in parts[1]:  # skip truncated placeholders
                      key, val = parts
                      env_vars[key] = val
  # Set non-referencing vars first
  for key, val in env_vars.items():
      if '${' not in val:
          os.environ[key] = val
  # Then resolve ${VAR} references
  for key, val in env_vars.items():
      if '${' in val:
          resolved = re.sub(r'\$\{(\w+)\}', lambda m: os.environ.get(m.group(1), ''), val)
          os.environ[key] = resolved
  

  ⚠️ Key gotcha: If bashrc contains LONGBRIDGE_ACCESS_TOKEN=m_eyJh...jb-k (with literal ...), it's a truncated placeholder, NOT a real token. Skip entries containing ... and prefer .env values.
• candlesticks() vs history_candlesticks_by_offset() Parameter Order: These have DIFFERENT signatures!
  • candlesticks(symbol, period, count, adjust_type) — count is 3rd
  • history_candlesticks_by_offset(symbol, period, adjust_type, backward, count) — adjust_type is 3rd, count is 5th
  • Always check signatures when switching between these methods.
• history_candlesticks_by_offset backward param: False = get older/historical data, True = get newer data from offset.
• calc_indexes Batch Size: LongPort accepts arbitrary symbol lists but errors/silently drops on very large batches. Safe batch size is ~10-20 symbols per call. For screener scripts (100+ symbols), iterate in batches of 10.
• python3 -c with HK Stock Codes: HK codes like 1088.HK, 3988.HK start with digits. Python parses them as 1088.HK → decimal literal error. Never use python3 -c for scripts containing HK stock codes. Always write to a temp file (/tmp/script.py) and run python3 /tmp/script.py instead. Same applies to any identifier starting with a digit.
• quote() fields: SecurityQuote has last_done, prev_close, volume, turnover, symbol. It does NOT have change_rate — use calc_indexes with CalcIndex.ChangeRate for price change %. Gotcha: accessing q.change_rate raises AttributeError: 'SecurityQuote' object has no attribute 'change_rate'.
• CLI Token Masking (Critical): The terminal tool masks/redacts secrets from environment variables, causing the longbridge CLI to get truncated tokens → 401004/403201 errors. The Python SDK always works because scripts read bashrc directly via open() and set os.environ programmatically. When CLI fails but SDK works, this is why. Always prefer execute_code + SDK over terminal + CLI for any order/trade operation.
• China Mainland Geo-Block (Error 602315): LongPort API blocks trading from mainland China IPs. Error: "Due to Mainland China regulatory requirements, you are currently located in Mainland China and cannot perform this action." (code 602315). Read-only operations (quotes, positions) may still work. Fix: Use WireGuard VPN via overseas VPS. On-demand scripts (wg-trade, wg-on/off/status) route only trading traffic through VPN. Full setup in references/wireguard-proxy-setup.md.
• API Rate Limiting (429002): LongPort enforces per-app request frequency limits. Error: api request is limited, please slow down request frequency (code 429002). Root cause: multiple scripts hitting the API simultaneously (e.g. DCA monitor + price alert both running at :00). Fix: (1) Stagger cron schedules by ≥15 minutes between LongPort-calling jobs; (2) Reduce polling frequency — 30min is enough for price monitoring, don't use 10/15min intervals; (3) Use market filters (--market=us/hk/cn) to reduce per-run API calls; (4) Add exponential backoff retry in scripts for transient 429 errors.
• source ~/.bashrc doesn't work in terminal tool: The terminal tool runs each command in a fresh shell that doesn't persist env vars from source ~/.bashrc. If Config.from_env() fails with "missing environment variable: LONGPORT_APP_KEY", use a Python script to parse bashrc directly:

  import os, re
  env_vars = {}
  with open(os.path.expanduser('~/.bashrc')) as f:
      for line in f:
          line = line.strip()
          if line.startswith('export LONGBRIDGE_') or line.startswith('export LONGPORT_'):
              parts = line.replace('export ', '').split('=', 1)

Dividend/Valuation Screener Pattern

📖 For HK-specific dividend investing (monthly dividend workarounds, entry price methodology, data sources), see references/hk-dividend-investing.md. 📖 For DCA scanner/monitor architecture (multi-market scanning, ladder alerts, cron scheduling), see references/dca-monitoring-architecture.md.

When user asks "which stocks have X% yield" or "find high-dividend stocks", use this pattern:

1. Pull watchlist symbols via ctx.watchlist() → all user's tracked stocks
2. Add a curated candidate list (BDCs, mREITs, MLPs, high-div ETFs, blue-chip dividend stocks)
3. Batch calc_indexes() with CalcIndex.DividendRatioTtm + CalcIndex.TotalMarketValue in batches of 10
4. Sort by yield descending, present in tiers (🔥 >20%, ⭐ 10-20%, ✅ 5-10%)

from longport.openapi import CalcIndex
import os, sys

cfg = openapi.Config.from_env()
ctx = openapi.QuoteContext(config=cfg)

# Step 1: Get all watchlist symbols
wl = ctx.watchlist()
watchlist_symbols = list({sec.symbol for group in wl for sec in group.securities})

# Step 2: Add high-yield candidate universe
candidates = [
    'HRZN.US','PSEC.US','SVOL.US','FSK.US','ORC.US','IVR.US',  # BDC/mREIT >20%
    'ARR.US','DX.US','AGNC.US','NLY.US','NYMT.US','CIM.US',     # mREIT
    'ARCC.US','HTGC.US','TSLX.US','MAIN.US','GAIN.US','GLAD.US', # BDC
    'JEPI.US','JEPQ.US','QYLD.US','SPYI.US','QQQI.US','DIVO.US', # 高息ETF
    'MO.US','VZ.US','XOM.US','BTI.US','O.US',                     # 蓝筹高息
    'ET.US','EPD.US','MPLX.US','USAC.US',                          # MLP
    '3416.HK','3417.HK','3419.HK',                                 # 港股高息ETF
    '1088.HK','0883.HK','3968.HK','1919.HK','2318.HK',            # 港股高息蓝筹
]
all_symbols = list(set(watchlist_symbols + candidates))

# Step 3: Batch calc (10 per batch)
results = []
for i in range(0, len(all_symbols), 10):
    batch = all_symbols[i:i+10]
    try:
        resp = ctx.calc_indexes(batch, [CalcIndex.DividendRatioTtm, CalcIndex.TotalMarketValue])
        for item in resp:
            dy = item.dividend_ratio_ttm
            if dy is not None:
                try:
                    dy_val = float(dy)
                    if dy_val > 5:  # Filter noise
                        cap = float(item.total_market_value) if item.total_market_value else 0
                        results.append({'symbol': item.symbol, 'yield': dy_val, 'cap': cap})
                except: pass
    except Exception as e:
        print(f"Batch error: {e}", file=sys.stderr)

# Step 4: Sort and present
results.sort(key=lambda x: x['yield'], reverse=True)

Note: DividendRatioTtm returns the trailing 12-month dividend yield as a percentage (e.g. 14.16 means 14.16%). This is dividend-per-share / price, annualized from actual payments — not a forward estimate.
