Per-symbol HOLD-STATE read — is the published trend state behind a name intact?
Per-symbol HOLD-STATE read — is the published trend state behind a name intact? GET /api/board/hold?sym=NVDA (up to 10, comma-separated, one price) returns each name's state, hold strength 0-100, readiness, maturity-late flag, overnight gap-risk grade and its book's regime, with the mechanical rules states flip on. BTC-USD/ETH-USD return the crypto book's IN|CASH daily-close state. Impersonal publication — never your entry or size. ~5-min refresh in market hours. Research, not advice.
