Thread: How to use an EA with a 5 digits broker

It is often asked on the forum if we can use an expert advisor on a 5 digits broker.

Yes, what you have to do is to multiply the stop loss, the take profit, the trailing stop and the break even by 10, that's all !

In the EA has "sleep number", what does this mean ? how it works ?

Hi EA fan and welcome,

The EA will stop to work during X seconds. For example, if you see Sleep(10000);, then the EA will stop to act during 10 seconds.

As long as there is money and a market. Except if there are some conditions to stop trading for example when a profit target has been reached.

Just attach it to the chart and it will do its job.

It is possible. You can open several Metatrader terminals on your computer or on a virtual private server. You will have to take care to the available memory in task manager (shortcut ctrl+alt+del).

Thank you for your quick reply.

When and why the EA need stop to work during X seconds ?

For example if there is a loss, and the system "prefers" to wait for better market conditions.

Thank you so much !

Right click on the windows bar (on the bottom of your screen), click on "task manager" and finally see "commit charge".

Then it depends on the system, if it needs a lot of memory or not. As long as you have 60-70Mb available for you system, it's ok.

For example, with 700Mb of memory, you can have up to 19 Metatrader terminals opened.

Of course, if you operate on your own computer and you do other activities, you will need more Mb.

My computer is 512 MB RAM, how do know how many % of RAM I am using ? and how many % of RAM using is safe ?

Thank you.

Hi EA fan,

In the task manager, click on "processes", you will have an idea about that.

Then for the safe % of RAM using, as long as you don't get a warning message from Windows saying that you have not enough memory, it's ok!

Thank you.

It depends on the code, it can take few seconds or few days. If the code is heavy you should do an optimization step by step. You optimize a parameter, then another one, etc... If the optimization is done fast, you can optimize several parameters at the same time.
