codeProp Firm Rule Checker

A simple diagnostic script that evaluates closed-trade history — from a live/demo account or the Strategy Tester — against the rules typically enforced by proprietary trading firm ("prop firm") evaluation challenges.

Instead of manually calculating drawdown, daily loss, and consistency after every backtest, run this script and get an instant PASS/FAIL breakdown in the Experts/Journal tab.

WHAT IT CHECKS

- Profit Target — did total profit reach the required percentage of starting balance?
- Max Daily Loss — did any single calendar day lose more than the allowed percentage?
- Max Overall Drawdown — how far did the balance drop from its peak, and did it breach the limit?
- Consistency Rule — did any single day generate an outsized share of total profit (a common rule at many firms to prevent one lucky day from carrying the whole challenge)?
- Minimum Trading Days — were enough distinct trading days logged?

HOW TO USE

1. Attach the script to any chart (symbol/timeframe do not matter — it reads deal history, not chart data), or run it right after a Strategy Tester pass.
2. Set the inputs to match the rules of the specific firm/challenge you want to evaluate:
   - InpStartBalance — challenge account size
   - InpProfitTargetPercent — required profit target
   - InpMaxDailyLossPercent — daily loss limit
   - InpMaxTotalDDPercent — overall drawdown limit
   - InpMaxSingleDayPercent — consistency rule threshold
   - InpMinTradingDays — minimum required trading days
   - InpFromDate / InpToDate — the period to evaluate
3. Read the report printed to the Experts/Journal tab. Each rule shows PASS or FAIL, plus an overall verdict.

NOTES

- This is a read-only diagnostic tool. It does not open, modify, or close any trades — it only reads history via HistorySelect().
- Rules vary between prop firms; always confirm the exact numbers from your firm's official rule sheet and set the inputs accordingly. This script does not represent or endorse any specific firm.
- Free to use and modify.

Cost is the one input to a trading system that is knowable exactly, and it is almost always estimated wrongly - always in the direction that flatters the strategy. This EA measures what one round trip really costs on YOUR broker: the live spread sampled from ticks, the swap for both sides including the triple-charge day, and the commission read from your own deals. Most spread figures come from the bar's "spread" field, because that is the easy one to reach. It is a per-bar summary, not the quote at any instant. Measured on XAUUSD: 20 points live across 60 readings against a bar-field median of 6. A factor of 3.3. So a filter set to "skip if spread > 15" never fires - it lets through exactly the moments it exists to block. Swap is the half most custom simulators do not charge at all. It is asymmetric, one side pays while the other collects, and one weekday counts three times. Read-only: it never opens, closes or modifies a position.
