What it does

Once installed, the agent knows the trading rules of several markets (China A-shares, Hong Kong stocks, US stocks, and crypto) such as daily price limits, settlement timing, short-selling rules, and basic tax treatment. When you ask it to build or test a trading strategy, it can apply these constraints so backtests don't assume trades that real markets would block. It is reference knowledge written as a guide, not a tool that pulls live data.

Great for

  • Quant traders building backtests across A-share, Hong Kong, US or crypto markets
  • Developers implementing trading rules like price limits and T+1 settlement in a backtesting engine
  • Anyone checking whether a cross-market strategy has hidden costs such as stamp duty or short-borrow fees

Skip it if

  • Giving legal or tax advice: the rules are summarised from memory, change often, and the file itself notes they must be checked against the date and the broker, so a professional should confirm anything that affects real money or tax filings
  • Live trading decisions: it contains no market data and some figures (fees, margin ratios, policy status 'as of 2026') may be out of date

Try asking

  • “Add A-share price-limit and T+1 rules to my backtest so limit-up buys aren't counted as filled”
  • “Compare the trading costs and short-selling fees of holding a pair trade across A-shares and Hong Kong”
  • “What are the PDT rules for a US margin account with under $25,000?”
  • “Check whether my strategy's stop-losses would still work under A-share limit-down conditions”

Get better results

  • State the market, date, and account type in your request, since rules differ by year and broker
