What is qmt-bridge-kline-backfill?

A QMT Bridge check for whether recent daily trading-value data is available for the Shanghai and Shenzhen markets. It normally uses current tick data and a local daily cache rather than downloading historical price bars.

Use it to check the last few trading days, identify missing turnover records, and optionally try to fill historical gaps for the relevant indexes.

It catches missing market-volume data before a trading review, so conclusions are not based on incomplete recent records.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00078	$0.01079
Opus 5.5	$0.00031	$0.00432
Sonnet 5.5	$0.00016	$0.00216
Haiku 4.5	$0.00008	$0.00108

Security

Grade A, and why

qmt-bridge-kline-backfill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/backfill_recent_index_kline.py, scripts/index_turnover_recent.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

QMT Trading Skill · 近3日量能校验

实现状态：✅ index_turnover_recent.py · backfill_recent_index_kline.py
共享逻辑：_shared/market_turnover_util.py

目标

在执行复盘前，校验近 N 日（默认 3）两市成交额是否齐全：

上证指数：000001.SH
深市指数：399106.SZ（tick 缺 amount 时回退 399001.SZ）

官方推荐 vs 本项目策略

迅投知识库（指数数据）：

场景	官方 API	本项目复盘热路径
当日成交额	`get_full_tick` → `amount`	✅ `GET /api/market/full_tick`
历史指数日 K	`download_history_data` + `get_market_data_ex`	❌ 禁用（易 BSON 崩溃）
历史缺口	需本地已下载数据	✅ `reports/market_turnover_daily.json` 每日 tick 累积

复盘/校验默认不调用 download_batch、get_local_data、get_market_data_ex、get_market_data。

可选 --try-history：先 download_batch 指数日线，再 get_market_data 子进程补历史并写入缓存（QMT 异常时慎用）。

推荐补齐近 3 日缺口（历史缺失时）：

# 1. 下载指数日线（仅 3 只，勿全市场）
python -c "
from datetime import date, timedelta
import sys; sys.path.insert(0,'skills/_shared')
from common import load_env_files, make_client
import argparse
load_env_files()
c,_=make_client(argparse.Namespace(host='127.0.0.1',port=8080,api_key='test-auto',account_id=None),False)
e=date.today().strftime('%Y%m%d'); s=(date.today()-timedelta(days=12)).strftime('%Y%m%d')
print(c.download_batch(['000001.SH','399106.SZ','399001.SZ'], period='1d', start_time=s, end_time=e))
"

# 2. 读 amount 写入缓存并展示明细

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
