Check out the new article: Engineering Trading Discipline into Code (Part 5): Account-Level Risk Enforcement in MQL5.

We introduce an MQL5 discipline engine that enforces risk consistently at the account level. It continuously scans positions from any source, validates SL/TP, equity-based exposure, and target R:R, and automatically corrects deviations by setting levels or adjusting volume. The result is uniform risk structure across manual and EA trades, supported by on-chart feedback and mode-based control.

In trading, risk rules are rarely the problem. The parameters are usually clear: a fixed percentage of equity per trade, a defined Stop Loss, a Take Profit derived from the same model, and a consistent risk-to-reward ratio. The real issue emerges after execution. Once positions are live, they can be modified, partially closed, or opened from multiple sources—including manual entries and different Expert Advisors operating across symbols. Over time, this leads to a disconnect between intended risk and actual exposure.

This breakdown follows recognizable patterns: positions without Stop Loss or Take Profit, lot sizes that exceed the defined risk threshold, or Take Profit levels that no longer reflect the intended risk-to-reward structure. In MetaTrader 5, there is no built-in mechanism that continuously validates these conditions at the account level once a trade has been placed.

To address this, risk must be treated as a set of enforceable conditions rather than static rules defined at entry. In this system, a position is only considered valid when all of the following are satisfied simultaneously: a Stop Loss is present, a Take Profit is defined, exposure is aligned with a fixed percentage of equity, and the resulting structure respects the configured risk-to-reward ratio. Any deviation from these conditions is treated as a violation.

This article introduces an account-level enforcement engine that continuously monitors all open positions, evaluates them against these conditions, and applies corrective actions when required. The focus is not on entry logic or signal generation, but on maintaining structural consistency of risk throughout the entire trade lifecycle.
