Can anybody advise me on which forex platform for my phone to make money with?

As far as I can see, it's an android, so get an android terminal.

To make money - it does not depend on the platform, but on the trader's ability

Hello.

I want to call myself in the indicator, but I get error 'MetaTrader4_Internal_Message' - parameter passed as reference, variable expected

 int hwnd=WindowHandle(Symbol(), Period());
 SendMessageA(hwnd, RegisterWindowMessageA("MetaTrader4_Internal_Message"), 14, WindowExpertName()); 

How can I correct it?

Have you tried iCustom()?

[Ghabo]

Artyom Trishkin:

Have you tried iCustom()?

Need to re-initialise the indicator.

iCustom() does not initialise it, or am I wrong?

[Artyom Trishkin]

Ghabo:

Need to re-initialise the indicator.

WheniCustom() is not initialized, or am I mistaken?

Write the following line into OnInit() of the indicator, called by iCustom(): Print(__FUNCTION__); and check it - it will be faster than waiting for an answer on the forum.

Artyom Trishkin:

Type the line: Print(__FUNCTION__); in the indicator called by iCustom() in OnInit() and check it - faster than waiting for an answer on the forum.

Yes it writes OnInit but then Stack overflow

Stack overflow, what is it?

Naturally :)

You have recursion. How long will the indicator call itself? You don't have to do it uncontrollably.

And in general - I do not understand why you need to call it from itself?

Try pouring the contents of the barrel into the glass.

At start it shows everything correctly, with time additional unnecessary lines appear, I can't fix it. When I call settings and click OK it shows only correct lines again. Initialising is a simple solution)

Hiding the shoals - a simple solution?

What are the lines? Where do they come from? When are they drawn? What do they build with?
