ASQ PropFirm Shield - library for MetaTrader 5

ASQ PropFirm Shield v1.2 — Free, Open-Source

One blown drawdown limit and your $100K challenge is gone. ASQ PropFirm Shield monitors every tick against your firm's exact rules — daily loss limits, maximum drawdown (standard or trailing), profit targets, consistency scores, and minimum trading days. It calculates exactly how much you can risk on the next trade without breaching anything. Built-in presets for 7 prop firms mean you drop it in and it just works.

FEATURES:

- 7 built-in prop firm presets — FTMO, MyForexFunds, Funded Next, The Funded Trader, E8 Funding, Bulenox, TopStep

- Daily loss limit enforcement — auto-blocks trading when daily limit is hit

- Maximum drawdown protection — standard or trailing, with floor lock for funded accounts

- 5-level shield state — Safe, Caution (>50% used), Danger (>80%), Breached (daily hit), Failed (max DD)

- Emergency close-all flag — triggers at 90% of any limit, recommends immediate position closure

- Risk-per-trade guardrail — WouldExceedRiskPerTrade() prevents oversized entries

- Safe risk amount calculator — returns the max $ you can risk on the next trade without breaching anything

- Profit target tracking with progress percentage

- Win rate & profit factor — live tracking from OnTradeClose() calls

- Consistency score calculation for firms that require it (MFF, FundedNext, Bulenox)

- Minimum trading day requirements with completion tracking

- Weekend holding prevention with Friday evening cutoff

- Challenge phase detection — Challenge, Verification, Funded with auto-target adjustment

- Daily PnL history (last 10 days)
