Promoting an EA from research to live at tiny size
Posted: Wed Oct 21, 2026 5:39 pm
There's a gap between "the backtest looks good" and "this runs with real money". A formal promotion process makes that step less of a leap.
A staged approach that some EA builders use:
Stage 1, research: backtest with realistic costs, walk-forward checks, parameter sensitivity. Exit criteria written in advance (e.g. profit factor above 1.2 after costs on out-of-sample data).
Stage 2, demo forward test: 4–8 weeks on a demo with the same broker and server as the live account. Compare each trade with what the backtest would have done over the same period.
Stage 3, live minimum size: the smallest lot the broker allows, for at least 100 trades. The goal isn't profit; it's to measure real slippage, rejects and behaviour around news.
Stage 4, scaled live: increase size in steps only if stage 3 results are within the expected range from stages 1–2.
At each stage, define what would send the EA back a stage: e.g. live slippage more than double the backtest assumption, or drawdown beyond the 95th percentile of the Monte Carlo estimate.
It feels slow. It's much cheaper than finding out at full size.
How do you decide when an EA is ready for real money?
