Passing a variable from an Indicator to EA

[Danja88]

Hi,

I am trying to get a value from an Indicator (that is not an array) and pass it to my EA.  I believe I need to pass the variable by reference, but am struggling on how this works (I am using MT5.)

Specifically, I am using Harmonic Pattern Finder V2 and would like to capture the value of D at the point in time it gets a value.  I have printed the value to the log, so I know it is what I want to capture and use.  I believe I need to make an include file that would be the go between.  Then would I have the indicator set a value in the include file and thus my would EA read this value for further use?  I am unsure how to approach this and would need some clarification on how passing values by reference really works.

I have been to Using the Object Pointers in MQL5 and there appears to be a bug in the code or an update breaks it.  The pstatus.GetMessage(); will return "Invalid Point Access" the way it is written.

Any kind of help or direction would be greatly appreciated!!

Thanks!

Interprocess communication (disk, pipes, shared memory, etc.) There is no "by reference."
