I am trying to compile the code provided in this tutorial but getting the error

iADX: wrong parameter count

at the following line

adxHandle=iADX(NULL,0,ADX_Period);

The code seems fine to me. How do I fix the error?

Could anyone help?

Carl Schreiber:
Which warning - which error messages in the Journal tab?

Unfortunately I get the same error message!

The advisor does not work with an ECN broker.

This is extremely frustrating that nothing works very well with the new MT5 and I want to switch to the newer version!

Thank you very much!

I don't have any experience with mt5 (yet), but mt5 recognises two account types hedging and netting - it's possible that these don't go together for you!

First opens 1 sell, then 1 buy and then a bunch of positions to buy, in the end all quickly drains. The code of checking for open positions is incorrect. I have not changed anything in the code

I tried to change the condition for opening a position at SAR crossing in the source code - it worked. Then I added the code of trailing (change of position by SAR) from the MQL5 reference book on the MqlTradeRequest structure. But it keeps generating the error [Invalid stops]. Apparently, something is wrong with the query. By the way, I am trying to study it (request to open a position) in different variants. And I got stuck on position modification. I don't understand at all, what am I doing wrong???? I have attached the Expert Advisor to this message.

Please tell me how to fix the code so that after take profit, the EA would not open a deal immediately, and waited for the next signal, for example, if the buy signal worked, closed at take profit, then wait for the sell signal.

After that only a new buy signal is triggered

Hello! very good tutorial, it's well explained, thank you!

But I have a problem, I got this error:
