TopstepX never reports the Maximum Loss Limit, but it's deterministic:
floor = min(0, eodBalanceHigh − trailingDrawdown), locking at the $0
starting balance. The EOD curve rebuilds from daily P&L + fund events,
with off-book fee drift spread across days proportionally to reported
fees (validated against a platform-reported MLL to ~$0.10). Stored in
autoLiqThresholds — negative, or +$0.01 once locked — so dead detection,
dashboards, and the ruin model's startThreshold all use the real room.
Guards move from '> 0' to '!== 0'; 0 still means no floor. canTrade=false
accounts are skipped. daily_pnl gains a fees column for the weighting.
