How to code? - page 60

New comment
 

thanks Kalenzo,

I have tried with OP_BUYLIMIT but it doesn't work.

I will try with OP_BUYSTOP.

 

quick coding question

How do you put a horizontal line on the screen at the average value (of all closing prices)? Is there a specific code for that?

How to turn indicator to EA?

Hi, may I know how to turn an indicator to EA?

Many indicators have the arrow sign when it comes to certain conditions and I would like to test them with EA.

I would like the EA to take the trade according to the arrow formed.

Can somebody help me? Thanks.

 

This one is according to arrow sign

What about to turn the attached indicator to EA?

Can someone help? Thanks.

Code Structure

Hi,

I am new to Metatrader but very experienced in programming. I have created some sample Expert Advisors and some slightly complicated Indicators in MT. What is not clear is how to structure a rather complicated EA. I want the EA to call some "signal" functions to check for different setup condition.

How should I code these functions?

1. As "inline" functions in the EA

2. As "separate" Indicators that return a value instead of write on the screen?

3. some other "separate" function to call like calling iMA

If I choose alternative 1 can the inline function in the EA run thru the last 200 bars using Close and call iMA?

Is alternative 2 OK?. When coding an indicator all bars "available" are processed which of course is not needed for the EA.

Alternative 3 to me seems like the logical choice but I am not sure how to structure it so it will work in backtesting and what I need to pass to it and what the function has access to by default, like for instance Close

As an example of what I need to establish in the "signal" function is what is the current trend and when did it start. I have coded it in an indicator so I know how to do the actual code.

Grateful for any advice.

You probably already know how to do this, so sorry if you do.

Moving average of current bar:

iMA(NULL,0,13,0,MODE_EMA,PRICE_CLOSE,0);

Moving average of 200 bars ago.

iMA(NULL,0,13,0,MODE_EMA,PRICE_CLOSE,200);

You can call the moving average from whatever bar you want form current to any bar in the past.
