On the Tradier live cash account buying_power maps to cash_available —
SETTLED cash. Capping every entry's notional at it means the bot never
spends today's sale proceeds today, which is the entire good-faith
-violation rule. That replaces the blunt 1-trade/day cap: the live
account now trades like paper (cap back to 5/day), throughput
self-limits at ~settled/position-size sequential trades and refreshes
each morning at T+1. On margin accounts buying power is ~4x equity so
the cap never binds — one universal rule, no broker branches. Fail-open
when the field is absent.
