Open lock

4.05

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.

Open lock for MetaTrader 5 is available here


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

Сова отличная, особенно если с умом её использовать! С её использованием 18 счетов вернулись к жизни ещё 73 в работе. В своей работе использую по 4 (6) экземпляра ОЛа на один инструмент с разными настройками для разных меджиков и для разных направлений (не использую его дефолтное применение в обе стороны одновременно). Сергею отдельное спасибо за постоянную работу над ОЛом, за внесение необходимого дополнительного функционала. Жду с нетерпением закрытие не в $, а в пунктах + альтернативные варианты закрытия (N крайних ордеров + целевой просаженный объём). Друзья, если у кого возникают сложности с настройкой - обращайтесь в чат разработчика - всегда подскажем.

OL is 5 years old, a few months it was on the 1st line of the mql5 market by popularity, more than 3,000 users, 5 years of development and 39 updates, dozens of hours of videos on YouTube and dozens of chat rooms on telegram with support. You bought the OL yesterday, did not read the instructions and have already given it one star. Did you really use it?

Сова отличная, особенно если с умом её использовать! С её использованием 18 счетов вернулись к жизни ещё 73 в работе. В своей работе использую по 4 (6) экземпляра ОЛа на один инструмент с разными настройками для разных меджиков и для разных направлений (не использую его дефолтное применение в обе стороны одновременно). Сергею отдельное спасибо за постоянную работу над ОЛом, за внесение необходимого дополнительного функционала. Жду с нетерпением закрытие не в $, а в пунктах + альтернативные варианты закрытия (N крайних ордеров + целевой просаженный объём). Друзья, если у кого возникают сложности с настройкой - обращайтесь в чат разработчика - всегда подскажем.

One of the best EA recovery tool. You need to understand how it works and optimize it. My set up is: lot size 3:1 or 4:1 and step 300 to 420

This tool is only for experienced traders who know well how to apply money management. 5 stars from me.
