v1.6.3 - Signals Endpoint Performance Improvement

The signals endpoint now queries a 3-day lookback window instead of 14 days when computing the latest smoothed signal, significantly improving response times for requests with many tickers.

Changed

• GET /signals - Reduced default lookback window from 14 days to 3 days - The internal query window used to compute the latest smoothed signal has been reduced from 14 days to 3 days. This provides ample data for the maximum 48-hour smoothing parameter while significantly improving query performance. The endpoint continues to return only the latest signal per ticker — no change in response shape.
