Output
A JSON object containing: signal direction ('long' or 'short'), a confidence score (0–1), take-profit percentage (tp_pct), stop-loss percentage (sl_pct), recommended hold time in seconds, the strategy ID ('vwap_reversion'), strategy name, the symbol, and a natural-language reasoning string explaining the signal.
Example use cases
SOL trade entry confidence check
“I'm thinking about entering a SOL trade right now — what's the current VWAP reversion signal saying, and how confident is the algorithm in this setup?”
SOL stop loss and take profit levels
“Before I place my SOL trade, can you pull the latest VWAP reversion signal and tell me the recommended take-profit and stop-loss percentages I should be using?”
Optimal SOL position hold time
“I just opened a SOL position based on VWAP reversion — what does the signal engine say about how long I should hold it, and is the signal still showing the same direction?”
Technical details
Endpoint
GEThttps://signal-engine-production-d88d.up.railway.app/v1/arena/vwap_reversion/SOLWhen to prefer
Use this endpoint when you need a fast, pre-computed algorithmic trading signal specifically for SOL using the VWAP reversion strategy, including actionable take-profit, stop-loss, and hold-time parameters ready for execution. Prefer this over generic price feeds when you need a complete trade recommendation with reasoning, not just raw price data.
Side effects
- Symbol not supported — endpoint is path-specific to SOL; other symbols may return 404
- No signal available — market conditions may not satisfy strategy criteria, returning null or empty signal
- Service unavailable — Railway-hosted service may be down or cold-starting
- Payment required — x402 payment of 0.001 USDC must be included or request returns 402
- Stale data — signal may reflect recently outdated market state during low-liquidity periods
