Hi Guru,

Could you make a small tutorial on how to open orders at the same time when eA is attached to different pairs? (the tutorial trades only one at a time.) I would like to trade many at a time, is this possible?

Thank you Codersguru. I am learning a lot from your lessons.

There is one question I would like to ask you.

Looks like your Expert Advisor is opening order at any time when 8/13ema cross takes place.
My question is what to do to force EA to open order exactly at the end of the candle, when the cross is really confirmed?

Regards
Govinda

Hi Govinda,

Thanks for you interest!

Use the cross of the previous bars:

PHP Code:


			
trend1 = iMA(NULL,0,8,0,MODE_EMA,PRICE_CLOSE,1);
trend2 = iMA(NULL,0,13,0,MODE_EMA,PRICE_CLOSE,2);
trend3 = iMA(NULL,0,8,0,MODE_EMA,PRICE_CLOSE,1);
trend4 = iMA(NULL,0,13,0,MODE_EMA,PRICE_CLOSE,2);

bool BuyCondition = false , SellCondition = false , CloseBuyCondition = false , CloseSellCondition = false ; 
   
   if(trend1 > trend2 && trend3 < trend4)
   {
       BuyCondition = true;
       CloseSellCondition = true;
   }
      
   if(trend1 < trend2 && trend3 > trend4)
   {
       SellCondition = true;
       CloseBuyCondition = true;
   }

Thank you very much for your fast reply.
I will have to digest and implement this peace of code... It may take some time...

OK. Looks like the key element here is “int shift” value of iMA function. Thanks for that clue CodersGuru

I have one more question to you

I also noticed that The EA does not reverse the position. At least my strategy tester did not find such reversals...
When the position is opened after the 8/13ema long cross very often it is closed when opposite cross appears. That is OK. But why after closing long position because of short ema cross the short position is not opened immediately (simultaneously)?
In this way strategy is loosing its full potential... I think...

Could you give some clue how to fix it?

With regards
govinda

An amazing course codersguru.

If you want to make the course even more accessible and useful, I would suggest an index of links to all lessons and appendices at the start of the thread (or maybe at http://www.forex-tsd.com/lessons/ ) - kept up to date.

http://www.forex-tsd.com/3746-post20.html contains an index to Lesson 14 and Appendices 1 and 2 but doesn't includes Lessons 15-18.

And there's probably more to come!

Thanx for all your hard work
