GET /api/ta/fvg
Scan for 3-candle Fair Value Gaps (SMC).
Return all unfilled 3-candle Fair Value Gaps for symbol in

GET /api/ta/volume-profile
Volume profile (POC/VAH/VAL) for a symbol
Compute a volume profile for symbol over [start, end].
mode=daily— EOD 1d bars via PostgresEODProvider, then :func:compute_volume_profile.mode=intraday— pre-aggregated 30m bins from themv_volume_bins_30mmaterialized view; POC/VAH/VAL are computed from the cached bin totals.
TA-013: warm path served from Redis (ta:vp:*, TTL 300s). Cache
failures degrade silently to the cold path — Redis is a perf
optimization, never a correctness dependency.
