The Expert Advisor helps to decrease the drawdown on the accounts.

To do this, a losing transaction is divided into many tiny parts, each of which is closed individually.

The Expert Advisor can socialize with other experts. to example, when a particular drawdown is attained, Open Lock can disable another Expert Advisor plus take over the job with transactions.

Open lock for MetaTrader 4 is available here

The EA’s algorithm uses counter transactions and a high number of open positions, so it requires a hedge account.

Averaging orders are opened in small lots, so as not to load the deposit.

The profit on these orders is used to close part of the unprofitable positions.

Recommendations for setting up and using Open Lock are described in my blog
