@Ravenash We have to ask the question why over time all the martignal EA’s lose with time
If we search on the web, we will find that all the EA’s that use the Martingale system allow opening more than 5 orders in the same time, or we may find that they reach more than 10 open orders.
Opening this number of orders will definitely cause the loss of all the amounts in the account, regardless of the strategy that the EA works with.
For this, for me, the Martinal EA, it must be set up not to open more than two orders as a maximum. Rather, it is preferable to open one order and not open another until after the previous closing
And test it with a demo account, then move to a cents type account. The amounts in the account will be converted into cents, which allows your account to take the risk of the Martinal system, and open each order with the lowest possible size, even if the broker has an account that allows opening orders with a size of 0.001, you set up a robot to open orders this size.
Doing these steps is the best way to set up an EA to test it, and so far I have not found EA’s that allow you to determine the number of open orders and at the same time the martignal is linked to losing orders only, but we find it linked to both types of orders results, whether winning or losing, and this is considered a high risk to the account
NB: You said that professionals do not use the martignal system, you cannot be decisive in this matter, because we all know that the majority of those who profit in a field do not like to appear in the forefront, and even if we consider that they do not use the traditional martignal system, but they use the multiplier system in another way where they open orders Its profit margin is multiplied by 5 times the loss margin or more. This for me is similar to the Martignal system, because we all know that all strategies, no matter how many winning orders are, the loss is chasing you, and so you try to find ways to avoid that loss by compensating for it.
