How this service works
The flagship signal: a single transparent 0-100 conviction score combining trend regime, volatility context, and relative strength vs other tracked assets -- with the full component breakdown shown, not a black-box model. Every number is independently verifiable via strategy-consensus, strategy-rank, or strategy-backtest.
Output
A JSON object containing the requested asset symbol, a composite score (0–100), individual component scores for trend (vs 200-day SMA), volatility (percentile), and relative strength (ranking among BTC/ETH/SOL), each with weight and human-readable detail, plus a conviction label (e.g. 'high_conviction') and a plain-text methodology explanation.
Example use cases
Pre-trade momentum check for Bitcoin
“Before I add to my BTC position, can you pull the latest composite signal for BTC and tell me if it's high conviction bullish based on trend and volatility?”
Cross-asset ranking for portfolio allocation
“Compare the trend composite scores for BTC, ETH, and SOL right now — which one has the strongest relative strength and lowest volatility percentile?”
Systematic signal feed for automated strategy
“Every hour I want you to fetch the composite score for ETH and log the trend component and conviction level so I can track how the signal evolves.”
Technical details
Endpoint
POSThttps://strategysignals.duckdns.org/tools/strategy-compositeWhen to prefer
Choose this endpoint when you need a transparent, verifiable, methodology-disclosed composite trading signal for BTC, ETH, or SOL — especially when you need to audit or backtest the underlying components (trend vs 200-day SMA, volatility percentile, cross-asset relative strength ranking) rather than trust a black-box model score.
Side effects
- Invalid asset symbol (must be BTC, ETH, or SOL) results in validation error
- Market data unavailability may produce stale or error response
- Payment failure (insufficient USDC) blocks request via x402 protocol
- Malformed request body (missing 'asset' field) returns schema validation error
- DuckDNS domain may have intermittent resolution issues reducing reliability
