Upvote Fold

Fold backtests a trading strategy from one sentence. Describe the strategy in plain English. Fold writes it, runs it on real historical data with the manifoldbt engine, and replies with the metrics, the exact strategy it tested, the engine’s warnings and an equity chart.

• /backtest: describe the strategy to test
• /symbols: list the markets you can test on
• /help: show the command list with examples

• RSI 30/70 on BTC 1h since 2023
• EMA 20/50 crossover on XAUUSD 4h, long only
• Breakout on EURUSD 1h: long above the 50-bar high, exit below the 20-bar low, 2 bps fees
• Equal-weight RSI 30/70 on COPPER, NATGAS and COFFEE, 4h since 2019
• Pair trade NQ vs ES 4h: z-score of the spread over 20 bars, enter at ±2, exit at 0

Crypto (Binance spot), forex majors, gold and silver, stock indices (US500, US100, US30, DE40, UK100, JP225) and commodities (oil, gas, copper, softs). Run /symbols for the full list.

• Give the market, the interval (1h minimum) and a start date. Anything you leave out, Fold chooses and tells you.
• Forex, indices and commodities pay their real bid-ask spread on every trade. Add fees in bps if you want commissions on top.
• A pair or spread trades both legs, in opposite directions.
• Read the warnings. They say when a result should not be trusted.

5 backtests a minute per member, one at a time, and 25 per server per day. The daily count resets at 00:00 UTC.
