The Expert Advisor helps reduce the account drawdown.

To do this, the losing deal is split into multiple small parts, each of these parts is closed separately.

The EA can interact with other experts. For example, when a certain drawdown is reached, Open Lock can disable the other expert and start working with its orders.

Methods used by the EA

1. Locking to prevent a drawdown increase
2. Averaging orders used to cover the loss
3. Partial closure to reduce the load on deposit

Averaging orders are opened with a small lot so as not to load the deposit.

Profit of these orders is used to partially close the losing position.

Recommendations on setting up and using Open Lock are described in the blog
