Prop Rules Guard MT4 is a utility (Expert Advisor) for MetaTrader 4 that keeps a prop-firm account inside its rules. It measures the daily loss limit and the max loss on equity, the way the firm does. At a safety buffer before a limit, it closes your trades and keeps the account flat until the firm's daily reset.
It never opens a trade. It works with manual trading and with other Expert Advisors on the same account.
Standalone: Everything is built in. You do not need to buy or install any other product named on this page.
MetaTrader 4 edition: the same rules, presets, lock and panel as the MetaTrader 5 version. MetaTrader 4 keeps orders, not deals: each closed order counts at its close time, with its profit, swap and commission. Like any MetaTrader 4 program, it sees the trades loaded in the Account History tab, so choose All History there (right-click the tab). The account size, the peaks and the trading days come from that history.
Quick start
- Attach the Guard to one chart and turn AutoTrading on.
- Pick your firm in "Firm preset", or leave Custom and enter the rules.
- Check the lock level (default 90% of a limit used) and what it closes: every position, this chart's symbol, or listed magic numbers.
- Set the news mode and the warning level, then watch the panel.
What it does
Daily and max loss
- Daily loss limit: measured on equity from the balance, the equity or the higher of the two at the reset. It is a % of the account size or of the day start.
- Reset: the firm's time and time zone, such as 00:00 Prague, 17:00 New York, 00:00 UTC+3 or server midnight. Daylight saving is handled.
- Max loss: static, or trailing from the highest equity, the highest closed balance or the highest end-of-day balance. It can stop at the account size. A two-stage type is also available.
Lock, consistency and news
- Lock: at 90% of a limit (adjustable), it deletes pending orders, closes positions and closes anything opened while locked. A restart or re-attaching does not lift a lock. A daily lock ends at the reset. A max-loss lock ends when you press Reset.
- Consistency: tracks your biggest profit day as a share of total profit. It shows today's profit cap that keeps you within the rule, with an optional stop for the day at the cap.
- News: alerts before high-impact USD releases from a built-in list, because MetaTrader 4 has no economic calendar. The list runs to December 2026, and after that the panel says the list has ended. It can also delete pendings or close positions before the firm's window opens. Inside the window it only warns, because at most firms a close inside the window is itself the violation.
Risk caps and targets
- Caps: floating-loss caps for all trades or per symbol, open risk at your stop losses against the room left, and positions without a stop loss.
- Targets: profit target and trading days on the panel, with an optional lock when the target is reached.
- Scope: every position, this chart's symbol, or listed magic numbers (0 = manual trades).
Firm presets
There are 22 presets, checked against each firm's own rule pages on 2026-10-16. FTMO: 2-Step, 1-Step, Instant. FundedNext Stellar: 2-Step, 1-Step, Lite, Instant. FundingPips: 2-Step, 2-Step Pro, 1-Step, Zero. E8: One, Signature. Alpha Capital: Pro 6%, 8%, 10%. Blue Guardian: 2-Step, 1-Step, Instant. Funded Trading Plus: 2-Step Classic. Instant Funding: Two-Phase, One-Phase Pro. The Custom preset takes any other rule set. Firms change their rules. The panel shows the date each preset was checked, so compare it with your firm's current rules.
Your firm is not listed? Send me a private message here on MQL5 with these details.
- Your firm and programme.
- The daily loss limit (% and what it is measured from).
- The daily reset time and time zone.
- The max loss and its type (static or trailing).
- Any consistency or news rule.
I will add it as a preset in the next update. Until then, the Custom preset takes the same settings.
Before you use it on a firm account
- Check your firm's policy on Expert Advisors. Some firms allow risk-management EAs, some need approval, some forbid any purchased EA. The Guard only closes trades, but it is still an EA.
- AutoTrading: it must be on. Otherwise the Guard can only warn. The panel turns red when it is off.
- The buffer lowers the chance of touching a limit. It cannot remove it. In a fast market, a gap or a closed market, a close can fill beyond the lock level, even beyond the floor.
- One chart: attach it to one chart only. A second copy on the same account stays inactive.

Strategy Tester
In the tester only, the Guard opens small demo trades so you can watch it lock and release in visual mode. On a live or demo account it never opens a trade. The news filter uses the same built-in USD list in the tester as on a chart.
How it was checked
- Rule engine: a test EA traded in the MetaTrader 4 Strategy Tester on EURUSD, GBPJPY, XAUUSD and BTCUSD. It used four daily resets: 00:00 Prague, 17:00 New York, 22:00 London on a server on Eastern European time, and server midnight. It made 61,411 trading operations, including partial closes and stop-loss closes. At 33,970 moments, an independent Python calculation from the raw orders checked the day start, each day's closed result and the trading days. It also checked the account size, the highest balance, the highest end-of-day balance and consistency. All matched.
- Lock test: in the tester on XAUUSD over 195 days of 2026, large demo trades kept driving the account to its daily limit. Extra demo trades ignored the lock, so the Guard had to close them. It locked 53 times, and on no day did the lowest equity go below the daily floor. This is a test result, not a promise: a gap can still fill beyond the floor.

Questions
- Does it stop rule breaks? It closes and blocks trading before a limit, but fills in fast markets can go further. It lowers the risk. It cannot ensure a pass.
- Will my firm accept it? That depends on the firm's EA policy. Ask the firm if you are unsure.
- Does it work with other EAs? Yes. It closes their trades too, unless you limit the scope by magic number.
- What if the terminal is off? Nothing runs while the terminal is off. A VPS keeps it running.

Trading involves risk. The Guard enforces limits you set; it does not predict the market and does not ensure that an account passes or stays funded.
