At the end of the code also Alert(result.retcode);

in the general log:

Well here's how to help you? First, you write that Sell Limit is not exhibited, you give extracts from the log. And now we are speaking about a Buy Limit order. So, the problem must be floating. In addition, you have never cited the statment. You claim that the order is not visible in reality. And the statment may help to clarify the situation.

How can I help you? First, you write that Sell Limit is not being placed, and you give excerpts from the log. Now we are talking about a Buy Limit order. So, the problem must be floating. In addition, you have never cited the statment. You claim that the order is not visible in reality. The statment may help you clarify the situation.

Neither Sell Limit nor Buy Limit is set, Alert(result.retcode) returns 10009. Where can I get this "statment", what do I need to do?

 
iv1986:

Run this code on my own. Note that you will get a division error of 0 on the non-binary symbols, as there is no initialising margin there.

In the code where I managed to run it, I had to add a volume check. Otherwise, the volume was equal to zero:

if (request.volume < SymbolInfoDouble(_Symbol, SYMBOL_VOLUME_MIN))
   request.volume = SymbolInfoDouble(_Symbol, SYMBOL_VOLUME_MIN);

After that, the order is set successfully. Also note that it triggers quite quickly - it is close to the price. Therefore, the order itself might not be noticed by you. The order will either become a position or be attached to it if the account type is netting.

The "History" tab of the "Toolbox" window. In the context menu select "Orders". Then select "Report" from the context menu - "HTML". But you will probably be able to see for yourself why the order is missing: its status will be marked "filled".

 

Found my 2009 script, but it now compiles with a warning:'M' - unrecognized character escape sequence 1.mq4 66 37

PapkaFiles    = TerminalPath()+"\MQL4\Files\\";//Путь к терминалу

Can you tell me what to tweak in the line to compile correctly?

Thank you!

Put a double backslash before MQL4
 
Hello, can you tell me if it's possible to connect a copying signal and a robot to an mt4 account and connect all this to the vps?
 
Artyom Trishkin:
Put a double backslash before MQL4
and before F as well. All slashes should be double slashes
