Backtest Studio

Commands ​

These are the only commands the AI may run. They live in the workspace's tools/ folder and do the same as the app's buttons.

bat
tools\compile.cmd <name>       :: compile only, prints errors and warnings
tools\backtest.cmd <name>      :: compile, then run the Strategy Tester; prints the key stats
tools\live.cmd start <name>    :: start trading it live in MT5
tools\live.cmd stop            :: stop live trading (closes MT5; positions stay open)
tools\live.cmd status          :: what is trading live, if anything
sh
tools/compile.sh <name>        # compile only, prints errors and warnings
tools/backtest.sh <name>       # compile, then run the Strategy Tester; prints the key stats
tools/live.sh start <name>     # start trading it live in MT5
tools/live.sh stop             # stop live trading (closes MT5; positions stay open)
tools/live.sh status           # what is trading live, if anything

<name> is the strategy's folder name. The commands call the app's own executable, which the app passes to the AI tools it starts (STUDIO_BIN). When you run from source, they call bun server/cli.ts instead, so you can run them from a terminal in the workspace folder too.

What a backtest prints ​

For example:

RUN 20260130-101500-london_breakout
Total Net Profit: 1250.40
Profit Factor: 1.42
Expected Payoff: 8.12
Total Trades: 154
Profit Trades (% of total): 81 (52.60%)
Equity Drawdown Maximal: 640.10 (5.80%)
Sharpe Ratio: 1.9
Recovery Factor: 1.95
History Quality: 100%
Matched trades: 154
Account rules: PASSED; daily loss worst 2.10% of 5% limit (0 breach days); max loss worst 4.20% of 10%

If MT5 is open, the command says so and stops: close MT5 and run it again. If another backtest is running, it says so instead of queuing.

tester.ini ​

Each strategy's test settings, which the app's settings panel edits:

ini
[Tester]
Symbol=XAUUSD
Period=H1                ; M1 M5 M15 M30 H1 H4 D1 ...
Model=1                  ; 0 every tick, 1 1-minute OHLC, 2 open prices, 4 real ticks
FromDate=2026.01.01
ToDate=2026.06.01
Deposit=10000
Currency=USD
Leverage=1:100

[TesterInputs]
InpFastPeriod=10

Only [Tester] settings and [TesterInputs] go here. The app fills in the rest (the expert, report path, shutdown, visual and optimization flags) when it runs the test.
