Hello Dear programmers

I have a question. I need an EA to close two specific orders on their total profit, without affecting other orders.

I have not managed to find anything suitable.

Thank you very much!

I would appreciate it if you would not spam me again. One post in one thread is enough to be heard. I've deleted the others.

That's where do such polite and patient moderators come from? I do not understand.

Help me fix an error in the EA code. I tried to write an EA based on Laguerre.mq4 indicator. I got an error when compiling it. The error location in the code is in bold. The indicator is located in the body of the Expert Advisor.

Two starts. Reread the textbook, deconstruct the typical EA structure.

I need an advisor reading from a trading system with a pattern. When the arrows of one indicator must open an order in the direction of the arrow and if it changes close the previous order and open a new one, setting stop-loss and take-profit.

I will write an advisor of any complexity. The main thing is to have a good idea. How you will use it I do not care: will sell - I do not mind (I will not ask for money).

P. S. If you need an indicator, you have to tell me the strategy in which you want to use it.

Hello! need a trading robot on MTD 4 . i can send pics with examples of trades. answer the mail please. [e-mail] All details on mail will forward. together with a photo and the description.

Well, can you correct the error so that I can see the mistake?

Do you know why no one corrects your code? Because it clearly shows that you haven't read the textbook, in which case it would be a difficult and probably useless conversation.

Hello, I need an EA which would place positions in both directions at a given distance from the market (e.g. Bay Stop and Sell Limit, optionally better to place in one direction), taking into account the spread. With possibility to enable trailers while the position is not in the market and move to Breakeven (according to flexible criteria) after it has been opened. And if there is an option to automatically open or close positions after previous positions are closed, it would be great.
