Trading Strategy Backtest Comparator
x402
Trading Strategy Backtest Comparator is a paid API for AI agents from strategysignals.duckdns.org, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-14).
Runs and compares two parameterized SMA/trailing-stop trading strategies head-to-head on BTC, ETH, or SOL, returning full performance metrics and equity curves for both.

How this service works
Does a 150-day or 200-day SMA actually perform better on this asset? Test two parameter sets head-to-head against the same asset and date range in one call, with both real results and a declared winner -- cheaper than paying for two separate backtests and comparing them yourself.
Output
Returns a JSON object with full results for both strategy A and B including: asset traded, parameter config, performance metrics (win rate, final equity, Sharpe ratio, total trades, max drawdown %, total return %), the actual data period covered, a timestamped equity curve, and a 'winner' field indicating which strategy outperformed.
Example use cases
Optimize SMA period for BTC
“I want to compare two BTC strategies: one with a 200-day SMA, 10-day cooldown, and 25% trailing stop versus one with a 50-day SMA, 10-day cooldown, and 25% trailing stop — same $5,000 starting capital from 2022-01-01 to 2024-12-31. Which setup gives a better Sharpe ratio and lower drawdown?”
Validate trailing stop tuning for SOL
“Run a head-to-head backtest on SOL starting with $2,000 from 2023-01-01 to 2025-06-01: strategy A has a 120-day SMA, 14-day cooldown, and 10% trailing stop; strategy B is identical but with a 30% trailing stop. Tell me the final equity, win rate, and which one wins.”
Historical ETH strategy research for blog post
“Backtest two ETH strategies from 2021-06-01 to 2026-01-01, both starting at $1,000 — strategy A uses a 150-day SMA with a 20% trailing stop and 14-day cooldown, strategy B uses a 90-day SMA with a 15% trailing stop and 7-day cooldown. Give me the full metrics including total return and max drawdown so I can compare them.”
Technical details
Endpoint
POSThttps://strategysignals.duckdns.org/tools/strategy-backtest/compareWhen to prefer
Choose this endpoint when you need to directly compare two parameterized systematic trading strategies (SMA + trailing stop + cooldown) against each other on BTC, ETH, or SOL with full performance metrics and equity curves. Prefer this over single-backtest endpoints when the goal is parameter optimization or A/B testing of strategy configurations. Best for quantitative research, strategy validation, or choosing between two trading setups with transparent, verifiable methodology.
Side effects
- Missing required fields (asset, strategy a/b params) returns validation error
- Unsupported asset symbol (only BTC, ETH, SOL accepted)
- Invalid or out-of-range date strings cause parsing errors
- Insufficient historical data for the requested date range may truncate results
- Network/server unavailability on duckdns.org dynamic DNS host
- Payment failure via x402 prevents execution
