MQL Programming question..

Hi. Does anyone know if it's possible to place 'wingdings' at XY co-ordinates (NOT Time/Price co-ords.) in separate windows??? I've being trying for about 2hrs and have reached the conclusion it can't be done. Can anyone provide a solution???

How do MT4 EAs handle trade errors?

I've read a lot about re-quotes and failed orders with different brokers, but I'm wondering how these are handled by EAs in MT4... if a price quote is outside the specified slippage will it just keep trying until it gets the price it wants, or will the trade be abandoned? What if the order is rejected for some server glitch or other... does MT4 keep trying to get the order accepted?

Many EAs rely on being able to place, modify or close a position when the proper time comes, and it seems to me it would be a disaster if it just bails out under error conditions. I'm just wondering if some EA guru could explain just how these situations get handled...

THX.

Custom Indicator Execute OrderModify()?

Hi

I have a custom indicator that works very nicely and I'd like it to modify my order at certain points. It seems like it doesn't want to execute an OrderModify() function and keeps returning error number 4055 just after I make the function call.

Can I run order functions buy/sell/modify etc from an indicator and if not can somebody offer a solution?

Thanks

MT4 file functions

hello, my Indicator uses the following code to record every trade signal to a text file. by default, the latest signal is the last record at the bottom of the file. what I want to do is to reverse this order. that is, I'd like my latest signal to come on top. does anybody know how to do this?

void Trade_Log(string type,string price,string sigBar)

{

//----

int handle = 0;

string log = "";

//----

log = type+"@"+price+" @ "+sigBar+" bars";

handle = FileOpen("lastSignal_.dat",FILE_BIN|FILE_READ|FILE_WRITE);

if(handle>0){ FileSeek(handle,0,SEEK_END);

FileWrite(handle,log);

FileClose(handle);

handle = 0;

}

//----

}
