Re: EA don't work in MT4

Actually I'm receiving the following message in the Journal:

OBOS MA Oscillator EURUSD M5Wrong MovingAverage parameters(Period: 186, Shift: 0, Source bars: 101)

It means that the MT History Tester has 101 bars but the OBOS MA Oscillator requires 186 bars to calculate the MA.
When I changed the "From" date of the test. The History Center run normally. It is not an issue of the expert.

Re: EA don't work in MT4

You can fix the problem by downloading data from the History Center - F2

Re: EA don't work in MT4

Thank you for your response.
Would you please give me a step by step explanation of what I have to do.
I downloaded the data yesterday before generating the project.
Where I have to change the from date:in the generator or in MT?
Thank you

Re: EA don't work in MT4

You can use the first part of this tutorial: Importing MT4 HST Data for info how to make MT4 loading historical data.

When the data are loaded, open the MT4 Historical Tester and set the testing data.

Re: EA don't work in MT4

Hi
I followed your suggestions.I was able to test the EA in MT from 10/01/2015 till 21/01/2015 successfuly.This test took around 100 minutes to complete although the data is previously downloaded.Is this normal?I tested many EA which took only few minutes.
Thank you for your help
