Prop Guardian (MT4) — review, price and free alternatives

The review focuses on how Prop Guardian enforces aggregate drawdown limits, how quickly it halts trading when thresholds are met, and whether the tool materially changes risk outcomes for FTMO-style evaluations and funded account compliance. Mohammad Rahchemandi designed the utility to act as a strict risk desk manager rather than as an entry signal generator, which is why the review emphasizes enforcement and behavioral controls.

What makes Prop Guardian unique is its dual approach: deterministic account-level rules plus a Psycho-Manager that encourages disciplined behavior after an enforced stop. The algorithm continuously monitors equity and floating P&L, compares them to configurable per-account and per-period thresholds, and then either blocks new orders or executes mass closures depending on configured risk tolerance. Prop Guardian does not attempt to read price action; instead it assumes position management and entry signals come from other EAs or traders.

The tool performs best in trending and moderately volatile markets where entry systems have predictable edges and occasional large losing streaks need hard stops. Risk management centers on fixed risk-per-trade caps and aggregate daily or trade-session limits, with flexible parameters to suit FTMO, MFF, and The5ers rules. Expected performance characteristics include fewer impulsive restarts after breaches, lower peak drawdowns by percentage, and improved pass rate for prop-firm challenges when rules are followed.

Prop Guardian represents a conservative to moderate risk control tool, with the primary objective of preventing rule violations rather than increasing returns. Stop loss strategy is enforced at the account level with options to close individual trades or stop all new orders when thresholds trigger. Position sizing is typically fixed risk-per-trade or percent-of-equity, with configurable caps to prevent oversized entries after wins. The main vulnerabilities are sudden market gaps, broker slippage, and execution delays during news events where forced closures may not achieve ideal fills. Recommended account size for reliable operation is at least 1,000 USD or equivalent to allow meaningful sizing while maintaining adherence to prop-firm margins. Prop Guardian is intended to reduce catastrophic drawdowns but cannot eliminate market risk entirely.

Install Prop Guardian on MT4 by copying the EA file to the Experts folder, restarting the platform, and attaching the EA to a chart. Configure key parameters such as daily drawdown limit, total equity stop, and risk-per-trade percentage in the EA inputs. Use brokers with stable execution, low commissions, and straight-through processing; avoid high-requote or market maker accounts for strict enforcement. Optimal chart timeframes depend on the signal provider; the EA is timeframe-agnostic but works well alongside M15 to H4 strategies. Test using a demo account and run at least three months of forward testing before deploying on a funded account.
