Open lock MT4 – Drawdown Reduction & Risk Control

The Open lock MT4 is designed to help reduce account drawdown and protect trading capital.

Instead of closing a losing trade all at once, the EA splits the losing position into multiple small parts. Each part is then managed and closed separately, which reduces pressure on margin and helps stabilize the account.

The EA can also interact with other Expert Advisors. For example, when a predefined drawdown level is reached, Open Lock can disable other EAs and take control of their open orders to prevent further losses.

🧠 Methods Used by the EA

The EA applies several professional risk-control techniques:

• Position Locking – Prevents further increase in drawdown
• Averaging Orders – Small-lot orders are used to compensate losses
• Partial Closure – Gradually reduces losing positions
• Low Deposit Load – Averaging orders use small lot sizes to protect margin

💡 The profit from averaging orders is used to partially close the losing position, reducing overall exposure step by step.
