How this service works
Backtest a stated trading rule on a crypto asset's daily USD closes (Coinbase Exchange) and compare it with buying and holding: SMA crossover, RSI mean reversion, DCA or buy-and-hold, 30-365 days, with fees. Returns total return, drawdown, Sharpe, win rate, exposure, every trade and the equity curve; the rules are published in every answer. Send {} for BTC, SMA 20/50, 180 days. A test of the past, not advice. Pay-per-call via x402.
Output
Returns a JSON object containing: total return percentage, maximum drawdown, Sharpe ratio, win rate, market exposure percentage, a chronological list of every trade executed (entry/exit prices, dates, P&L), the full equity curve, and a side-by-side comparison with a buy-and-hold baseline over the same period. The strategy rules used are also returned for transparency.
Example use cases
SMA crossover strategy evaluation
“Backtest an SMA crossover on ETH over the past 365 days — fast MA of 20 days, slow MA of 50 days, starting with $5,000 and a 0.1% fee. How does it compare to just holding ETH?”
RSI mean reversion profitability check
“Test an RSI mean reversion strategy on SOL: buy when RSI drops below 30, sell when it goes above 70, 14-day RSI period, $2,000 starting capital, 10 bps fee, over the last 90 days — did it beat buy-and-hold?”
DCA vs buy-and-hold comparison
“Run a dollar-cost averaging backtest on BTC over the past 180 days — buy every 7 days, starting with $10,000 total capital, with 10 basis points fee per trade. How does DCA compare to just buying and holding from day one?”
Technical details
Endpoint
GEThttps://fiatdock.com/v1/market/backtest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to quickly evaluate whether a specific trading rule (SMA crossover, RSI, DCA, or buy-and-hold) would have historically outperformed a passive strategy on a Coinbase-listed crypto asset. Ideal for quantitative research, strategy screening, or educational exploration of crypto trading rules with realistic fee modeling. Prefer it over manual calculations or general-purpose data endpoints when you need a complete performance report including drawdown, Sharpe, win rate, and equity curve in a single call.
Side effects
- Invalid or unsupported asset ticker returns an error (asset must have a USD market on Coinbase Exchange)
- 'fast' SMA period must be strictly less than 'slow' period or validation error is returned
- Days parameter outside 30-365 range returns a validation error
- RSI buy threshold must be below 50 and sell threshold must be above 50
- Coinbase Exchange historical data unavailable for the requested period may cause incomplete results
- Payment failure via x402 results in a 402 response before computation occurs
