Algo Risk Test

Smoke-test the risk manager and portfolio caps without risking real capital.

Arguments

$0 = path to a strategy file (e.g. strategies/ema_crossover_SBIN/strategy.py).

If not given, list available strategies and ask.

Pre-flight

Tell the user:

1. Flip OpenAlgo's analyzer toggle ON in the UI: visit http://127.0.0.1:5000/analyzer and click "Sandbox Mode". This routes all orders to the sandbox engine, no broker.
2. Confirm client.analyzerstatus() returns analyze_mode: True:

   from openalgo import api
   c = api(api_key="...", host="http://127.0.0.1:5000")
   print(c.analyzerstatus())
   # -> {data: {analyze_mode: True, mode: "analyze", ...}}
   

3. The strategy will run in --mode live but orders are simulated.

Instructions

1. Read the strategy file to extract:

   • SYMBOL, EXCHANGE
   • RISK (sl_pct, tp_pct, trail_pct, time_exit_min)
   • Indicator parameters

2. Generate a sibling risk_test.py in the same folder. Pattern:

"""
Risk verification harness for <strategy_name>.

Runs the strategy in --mode live (with OpenAlgo sandbox toggled ON).
Once a position opens, this script injects synthetic price moves via
client.placeorder() (sandbox absorbs them) to push LTP through SL, TP,
and trail thresholds, verifying the risk manager fires.

Usage:
    # In one terminal:
    python strategy.py --mode live
    # In another:
    python risk_test.py

    # the LTP move (via WS) and fire placesmartorder(position_size=0) to flatten.

    main()

3. Tell the user how to run:

   # Terminal 1: run the strategy in live mode (OpenAlgo sandbox active)
   python strategies/ema_crossover_SBIN/strategy.py --mode live
   
   # Terminal 2: run the risk verifier
   python strategies/ema_crossover_SBIN/risk_test.py
   

4. Note that OpenAlgo's sandbox doesn't accept arbitrary "set LTP" commands. Real verification of the risk manager often needs:

   • Letting the strategy run during market hours (sandbox uses real LTP)
   • Watching for the signal to fire and then timing the test to coincide with a real adverse price move

   Or: temporarily lower SL_PCT to 0.0001 (1 bp) so any tick triggers the SL - confirms the WS feed and exit path work.

Manual checks

If automated synthetic injection isn't possible (sandbox limitations), the user should:

• Run the strategy in sandbox during market hours
• Confirm WS connects and ticks flow (set verbose=True temporarily)
• Confirm a real adverse move fires placesmartorder(position_size=0) (check tradebook() for the closing trade)
• Confirm core/risk_manager.py's _check_exits() log line appears with reason=SL_PCT/TP_PCT/TRAIL

What to verify

Avoid

• Do not run risk tests with analyze_mode: False - real broker orders WILL fire
• Do not use icons/emojis
