Zigzag indicator

[Antoine]

Hello,

I would like to use the values of the Zigzag indicator in my EA for define the stoploss value.

How can I do??

Thank you.

 

Antoine.

Please read this help topic at first.

Ok but I have to use values calculated by the Zigzag indicator, and the iZigzag handle doesn't exist and I can't use values calculated on the OnCalculate part in the OnTick part .

So there is another solution or am I wrong???

How did you get to know that handle doesn't exist? Did you call the GetLastError() function?

[Antoine]

I tried to write indicatorHandle=iZigzag() but no information appear (like when you write iMACD()).

There is no function like iZigZag (or something like this) in MQL5. This indicator is implemented into standard delivery only as custom indicator (https://www.mql5.com/en/docs/indicators). So to get handle to ZigZag indicator you should use function iCustom(...)

[Antoine]

Thank you but I don't really confortable with the function iCustom()... I'm a newbie with MQL5 and progamation in general...

Can you help me for implement the code for the zigzag indicator please??...

 Thank you.

See attach my code which run well if someone need....

It searchs and store values in 2 variables for High and Low values

Hello Antoine.

 

Are u stiill here? Do u have idea how to translate this code to the MetaTrader 4. There are no functions as CopyHigh, CopyLow, CopyBuffer. Do u have any idea? 

 

OR

 

Your code is nice. I would like to made code what will store last few highs and lows of ZIGZAG.. And after that I wanna do some comparisions and get to the long or short after known rule 1-2-3.

Of course after some other filters will be applied.

But first i really would like to know how to develop easy strategy for known 1-2-3 (A-B-C) using ZIGZAG with pending stop orders.

So, please, do u know about anything what is clear to understanding? 

 

Thank you in advance. Have a nice day!
