A question for somebody smart?

Let's say I have a chart indicator on the screen like a MACD indicator.

Instead of changing the indicator parameters manually from the screen, how is this done from MQL source code?


I don't really NEED the visual indicator. For perfections' sake; however, I just want the visual indicator on the chart to accurately reflect what I have in my

code. My indicator parameters are dynamic. Therefore, changing the parameters manually would be burdensome.


Again, how is this done automatically from the source code?

Do I have to use a custom indicator so that the parameters can dynamically be changed through the terminal global variables?

Is there a simpler solution?

 
May be command iCustom() helps you?
 

Try using

GlobalVariableSet("VariableName",VariableValue) in your EA or indicator

and then use

GlobalVariableGet("variableName") in your other indicator.

In your dynamic program set your variable name and value then read that value in your other indicator.

EXAMPLE:-

Program 1 Does this:

GlobalVariableSet("CCIMA_CCIPeriod"+Period(),CCIPeriod);

GlobalVariableSet("CCI_MAUpperLevel"+Period(),CCIUpperLevel);
GlobalVariableSet("CCI_MALowerLevel"+Period(),CCIlowerLevel);

Program 2 does this:

CCIPeriod = GlobalVariableGet("CCIMA_CCIPeriod"+Period());


CCIUpperLevel = GlobalVariableGet("CCI_MAUpperLevel"+Period());
CCILowerLevel = GlobalVariableGet("CCI_MALowerLevel"+Period());
