How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing the coin ticker (SOL), the backtest window in days, and a summary block with win_rate (percentage), sharpe_ratio, total_trades count, and profit_factor, along with the strategy name (analyst_v3).
Example use cases
Evaluate SOL signal reliability
“Before I start trading Solana, can you pull the backtested signal summary for SOL so I can see how reliable the analyst_v3 strategy has been — specifically the win rate and profit factor?”
Compare Sharpe ratio before investing
“I'm deciding whether to allocate part of my crypto portfolio to Solana signals. Grab the analyst_v3 backtest metrics for SOL and tell me if the Sharpe ratio looks strong enough to justify the risk.”
Audit trading strategy performance history
“Run a quick audit on the analyst_v3 strategy for SOL — I need the total trade count, win rate, and profit factor from the backtest so I can decide if it's worth automating live trades around it.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/signal-backtest/SOLWhen to prefer
Use this endpoint when you need quantitative backtested performance metrics (win rate, Sharpe ratio, profit factor) for Solana trading signals from the analyst_v3 strategy, especially when evaluating signal reliability before acting on live signals. Prefer it over generic price feeds when the goal is strategy evaluation rather than current price lookup.
Side effects
- Coin not supported — endpoint is hardcoded to SOL, other tickers may return 404 or empty
- Payment not received — x402 payment of 0.1 USDC required per call; missing payment returns 402
- Upstream data unavailable — market data feed outage may cause 503 or stale results
- Invalid backtest window — if a days parameter is out of range, may return an error or fallback default
