3 endpoints in this group.

`GET /api/ta/fvg`

Scan for 3-candle Fair Value Gaps (SMC).

Return all unfilled 3-candle Fair Value Gaps for symbol in [start, end] using bars from provider at interval.

Today the only wired provider is postgres_eod (1d). Intraday intervals become available as intraday providers land.

Parameters

Name	In	Type	Required	Description
`symbol`	query	string	required	Ticker symbol
`start`	query	string	required	Inclusive range start (ISO date/datetime)
`end`	query	string	required	Inclusive range end (ISO date/datetime)
`interval`	query	string	optional	Bar granularity, e.g. ‘1d’
`provider`	query	string	optional	OHLCV provider name. Default: postgres_eod (1d only).

`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 the mv_volume_bins_30m materialized 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.

Parameters

Name	In	Type	Required
`symbol`	query	string	required
`mode`	query	string	optional
`start`	query	string	required
`end`	query	string	required
`bins`	query	integer	optional
`va_pct`	query	number	optional
