How this service works
What would $1,000 have become if you'd followed this rule historically? On-demand parameterized backtest of the 200-day-SMA + trailing-stop methodology against real historical data -- caller supplies asset, SMA period, trailing-stop %, cooldown, and date range; returns real computed performance metrics and equity curve.
Output
Returns the asset tested, all strategy parameters used, a metrics object with total_return_pct, final_equity, sharpe_ratio, win_rate, max_drawdown_pct, and total_trades, the actual data period covered, and a timestamped equity_curve array showing portfolio value over time.
Example use cases
Evaluate BTC strategy before live trading
“Before I put real money in, can you backtest a Bitcoin SMA strategy from 2022-01-01 to 2025-01-01 using a 200-day moving average, 10-day cooldown, 15% trailing stop, and $5,000 starting capital — I want to see the win rate and Sharpe ratio.”
Compare SOL trend-following over bull run
“Run a backtest on SOL from 2021-01-01 to 2023-12-31 with a 100-day SMA period, 7-day cooldown, 25% trailing stop, and $2,000 starting capital — I'm curious how the equity curve looked during that bull market.”
Verify published strategy claims
“I read someone claiming their ETH trend strategy returned 180% since 2021 with a Sharpe above 0.9 — can you run that backtest yourself using a 150-day SMA, 14-day cooldown, 20% trailing stop, $1,000 starting from 2021-01-01 to 2026-07-01 so I can independently verify those numbers?”
Technical details
Endpoint
POSThttps://strategysignals.duckdns.org/tools/strategy-backtestWhen to prefer
Choose this endpoint when you need a transparent, parameter-configurable SMA+trailing-stop backtest on BTC, ETH, or SOL with independently verifiable results and a full equity curve — particularly when you want to validate published strategy claims or tune parameters like cooldown days and trailing stop percentage rather than trusting a black-box signal provider.
Side effects
- Invalid asset symbol — only BTC, ETH, SOL are supported; returns validation error
- Date range outside available historical data — actual_start/actual_end may differ from requested
- Malformed ISO date strings — endpoint returns 400-level error
- Starting capital or parameter values out of acceptable range — validation error
- Service unavailable on duckdns host — DNS or uptime failures possible for self-hosted endpoint
- Payment not completed via x402 — request blocked without $0.25 USDC payment
