# TASignal Backtest > TASignal Backtest is a paid API for AI agents from tasignal.agentgate.workers.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-30). Runs rule-based strategy backtests (SMA/EMA cross, RSI reversion, Donchian breakout, MACD cross) on crypto assets using historical candle data, returning trade list, equity curve, and performance metrics. ## Facts - Endpoint: GET https://tasignal.agentgate.workers.dev/v1/backtest?utm_source=zero.xyz - Price: $0.05/call - Payment: x402 - Status: unknown - Last checked: 2026-10-30 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/tasignal-backtest-ad7e2872 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_GTaH0eIfUMn0-cfj1-Kf4 Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability tasignal-backtest-ad7e2872 ``` Example prompt: Run a backtest on SOL using an EMA cross strategy with fast period 20 and slow period 50 on 4-hour candles, long only, with 5 bps fees per side, over the last 500 bars — give me the total return, Sharpe ratio, max drawdown, and trade list. ## When to prefer this Use this endpoint when you need a rapid quantitative backtest of a rule-based strategy on a crypto asset with realistic fee modeling, next-open fill assumptions, and standard performance metrics (Sharpe, drawdown, win rate) — especially when you want to compare strategy performance vs. buy-and-hold. Prefer this over manual analysis when the user wants to evaluate SMA/EMA cross, RSI reversion, Donchian breakout, or MACD cross rules across multiple timeframes without building their own data pipeline. ## Known failure modes - Invalid or unrecognized symbol returns error — use base ticker like BTC, ETH, SOL - Unsupported strategy enum value returns validation error - Bars outside 100-2000 range rejected - Hyperliquid data unavailable and dYdX v4 fallback also fails — returns source error - Insufficient candle history for the requested bars/timeframe combination - Fast period >= slow period may produce degenerate results ## How this service works Technical analysis, risk analytics and backtests for trading agents in one x402 API: RSI, MACD, EMA 20/50/200, Bollinger Bands, ATR, ADX, stochastic, realized volatility and a descriptive technical bias score for any crypto asset on 15m/1h/4h/1d candles; historical VaR/CVaR, max drawdown, Sharpe/Sortino and ATR-based position sizing; and rule backtests (SMA/EMA cross, RSI reversion, Donchian breakout, MACD cross) with fees, next-open fills, trade list and equity curve. Candles from Hyperliquid with dYdX v4 fallback. Read-only analytics; free preview and remote MCP. Not financial advice. Not financial advice. Past performance does not guarantee future results. Technical indicators, risk metrics and backtests describe historical prices only; they are not predictions or trade recommendations. TASignal never trades, holds funds or keys. ## Output Returns a JSON object with backtest period metadata, strategy parameters used, trade count, list of last trades (entry/exit price, return %, timestamps), a sampled equity curve, win rate, profit factor, Sharpe ratio (annualized), max drawdown, total and annualized return, buy-and-hold return, excess return vs buy-and-hold, exposure percentage, current position, fees applied, data source, confidence level, and a disclaimer. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "symbol", "strategy" ], "properties": { "bars": { "type": "integer", "description": "Candles to test, 100-2000 (default 500)" }, "fast": { "type": "integer", "description": "Fast period (sma_cross/ema_cross default 20, macd_cross 12)" }, "slow": { "type": "integer", "description": "Slow period (sma_cross/ema_cross default 50, macd_cross 26)" }, "lower": { "type": "number", "description": "RSI entry level for longs (default 30)" }, "upper": { "type": "number", "description": "RSI entry level for shorts / exit (default 70)" }, "period": { "type": "integer", "description": "RSI period (default 14) or breakout lookback (default 20)" }, "signal": { "type": "integer", "description": "MACD signal period (default 9)" }, "symbol": { "type": "string", "description": "Base asset ticker, e.g. BTC, ETH, SOL, HYPE (BTC-PERP, ETH-USD and SOLUSDT are accepted too)" }, "fee_bps": { "type": "number", "description": "Fee per side in basis points (default 5)" }, "strategy": { "enum": [ "sma_cross", "ema_cross", "rsi_reversion", "breakout", "macd_cross" ], "type": "string", "description": "Strategy rule" }, "direction": { "enum": [ "long_only", "long_short" ], "type": "string", "description": "default long_only" }, "timeframe": { "enum": [ "15m", "1h", "4h", "1d" ], "type": "string", "description": "Candle timeframe: 15m, 1h, 4h or 1d (default 1h; risk default 4h)" } }, "description": "Search intents: crypto backtest api, backtest trading strategy, sma crossover backtest, rsi strategy test, trading strategy api, quant backtesting" } }, "additionalProperties": false }, "o … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "tier": "backtest", "market": "SOL", "result": { "period": { "to": "2026-10-22T16:00:00.000Z", "bars": 450, "from": "2026-08-08T16:00:00.000Z" }, "trades": 2, "assumptions": "Signals on candle close, fills at the next candle open, fees per side as set; no slippage, funding, borrow or liquidity limits; position size 100% of equity, no leverage.", "last_trades": [ { "exit": 99.676, "side": "long", "entry": 76.373, "exit_time": "2026-09-10T16:00:00.000Z", "entry_time": "2026-08-08T16:00:00.000Z", "return_pct": 30.447 }, { "exit": 115.84, "side": "long", "entry": 105.74, "exit_time": "2026-10-07T20:00:00.000Z", "entry_time": "2026-09-18T12:00:00.000Z", "return_pct": 9.497 } ], "equity_curve": [ [ "2026-08-08T16:00:00.000Z", 0.99632 ], [ "2026-08-23T16:00:00.000Z", 1.24486 ], [ "2026-09-07T16:00:00.000Z", 1.36524 ], [ "2026-09-22T16:00:00.000Z", 1.45808 ], [ "2026-10-07T16:00:00.000Z", 1.42764 ], [ "2026-10-22T12:00:00.000Z", 1.42693 ] ], "exposure_pct": 69.78, "win_rate_pct": 100, "avg_trade_pct": 19.972, "profit_factor": null, "sharpe_annual": 3.869, "current_position": "flat", "max_drawdown_pct": -10.327, "total_return_pct": 42.693, "fees_bps_per_side": 5, "annualized_return_pct": 464.18, "buy_and_hold_return_pct": 36.933, "excess_vs_buy_and_hold_pct": 5.759 }, "source": "hyperliquid", "symbol": "SOL", "strategy": { "name": "ema_cross", "params": { "fast": 20, "slow": 50 }, "direction": "long_only" }, "timeframe": "4h", "checked_at": "2026-10-22T19:00:54.904Z", "confidence": "high", "disclaimer": "Not financial advice.
