Api V2 Scorecard Signal-Record Get

Per-signal flip record over the last sessions trading days.

The daily scorecard is one calendar day, which cannot answer "is this signal any good" — the question a subscriber actually asks after a signal calls one session correctly. This is the same flip definition and the same session-bounded forward return, aggregated over a window.

Params:

• symbol — underlying (default SPY).
• sessions — trailing weekdays to cover (2–120, default 30).
• horizon_minutes — forward window (5–240, default 60).
• signal — one signal name; omit for all of them.

Returns: signals[] with flips, scored, wins, losses, win_rate and avg_directional_return per name.

scored can be lower than flips, and win_rate is null when nothing was scorable. A signal that only fires near the close (eod_pressure) can have many flips and few scorable ones; that is the honest shape of the measurement, not a defect to paper over.
