Stop arguing. Start verifying.
Every trading forum is people insisting their strategy works. None of them show the beta-stripped, fee-included numbers. You do not have to join that argument — you can just test your idea and look at the truth.
The Build Your Own mode is a full strategy lab. No code, no signup, real OKX fees baked in. Here is everything you can construct.
What you can build, piece by piece
Indicators (13 families). Pick any of Bollinger, EMA, RSI, MACD, ATR, historical volatility, Stochastic, ADX, Ichimoku, Parabolic SAR, Williams %R, volume, candle patterns — and tune their parameters (RSI period, BB standard deviation, EMA fast/slow, and so on). The exact knobs the strategy actually uses.
Entry conditions. Compose any rule with AND/OR logic: “RSI < 30 AND price > EMA200”, “MACD crosses below signal”, “Bollinger lower-band touch”. Reference one indicator against another, or against a value, on the current or previous candle.
Direction. Long, short, or both.
Exits — every kind. Fixed take-profit / stop-loss, a trailing stop that follows the high, or a signal-reverse exit (close when your own exit conditions fire — e.g. exit a long when MACD turns down). This matters, because the exit reshapes your win rate but not your expectancy — and now you can prove that to yourself.
Universe & timeframe. All coins, the top N by liquidity, or a custom basket. 1H through 1W. Avoid specific hours if you want.
Save and share. Every strategy you build encodes into a link — send it, revisit it, compare it.
The one number that matters
When the backtest finishes, ignore the win rate. Look at the return after fees and the profit factor, and remember to ask whether the edge survives the market move (is it beta?). A 70% win rate with a negative expectancy is a losing strategy that feels like a winner — the most expensive illusion in trading.
Why we built this
Because the honest answer to “does this work?” is not our opinion — it is your own backtest, run correctly, with real costs, that you can reproduce. We show you what failed in our own research. The builder lets you confirm it, break it, or find the rare thing that holds. Open it and try your idea.
