I've been away a while.. lots changed! But today I'm getting ObjectFind return "true" when there is no object with that name... void OnStart () {    if ( ObjectFind ( 0 , "456" )) Alert ( "found: 456" );    else Alert ( "not

Just found exceeding the data type max and min values doesn't trigger any kind of error message... just silently wraps around :/ e.g. int a = 2147483647 ; int b = a+ 1 ;   //b is -2147483648 !? Are there are any simple ways of safeguarding

Hi, I used simple code to write the ticks to file and found that indicators wrote more ticks than the same code in an EA. I used two EURUSD M1 charts in the same instance of MT4. I swapped the charts and got the same results Here is the results from

Is there a way to call a function in a DLL file (I'm using C++) and let it run while MT4 retains control. Specifically, it's for a tick collector. I would like the DLL to periodically write the logs to file, but I don't want to miss any incoming

Hi all, hoping for some input on this from your experience or viewpoint. After a getting results from a parameter sweep, how do you analyse the data to find 'patches' of good results. I mean, if you have a good set, but change one parameter slightly

A custom indicator generated this error but unfortunately it's one I gave to my friend and I've ben unable to replicate it myself. The very general error description doesn't really help with where to start looking for this. Has anyone else

Hi all, I'm trying to calculate a cross currency price from two majors. I get close but not exactly. The broker is variable spread. E.G. EURUSD bid:1.35000 ask:1.35002 GBPUSD bid:1.59290 ask:1.59297 EURGBP bid: 0.84747 ask: 0.84756 dividing the bids

Well. Stage 1 of my MT4 life is complete. I have an EA that earns a good profit on demo accounts. But I think it's too good to be true as profits are directly affected by the brokers' processing times of OrderSend and, in particular, OrderModify. Am

In many of my indicators I record data in folders organised by brokers. I just 'improved' my code for getting the broker name. If I add the indicator, no problems. However, if I close and reopen Mt4, it crashes. Can't see the program, CPU 100%. If I

I think somewhere in "The Book" if says having user defined functions is slightly less efficient (but much clearer to read and program). I'm wondering if I can use user defined functions while writing the EA, and then, when it's time to

Feel free to ignore this if you want, it's a little simple, but I hope someone can explain this aspect of programming to me? I tried to find the number of points between 2 prices (i.e. an integer like 10 points, or 2 points)

At the moment I'm creating an array with 7 entries like this: string      readline[ 7 ]; But I'd like to put the code in a .mqh file and then #include it in many files, with different sizes of the array. I tried to do this: int

Amazingly, I can't find easy free historical price data so I'm going to write a script to export to csv for us in excel. Just before I start I wanted to check that I'm not missing an easier way to do this...? Also, is there an easy mql way to make it

I wrote a script to add lines to a chart (once) Now I want to be able to input some boolean variables as it runs. Is it possible to have a script ask you for inputs? Alternatively, to the same end, can a custom indicator remove itself after it's

Hi all, I've been saving a few small questions to ask in 1 go: 1) is there any disadvantage to use Ask, Bid, Digits, Time[] etc. many times within a function ... I see many people assign it to a variable such as "askprice" etc. and then use that

Hi, on two brokers, I have the lines appearing wrongly. On the first one, the ask price is consistantly 1 points too low. The pink box is my indicator showing what the spread should be based on the Market Watch window figures and it SHOULD match up

Hi all, I want a script that copies the objects of all open charts and pastes them on all open charts. Searching tells me I will need to use winAPI to access other charts? Any tips one what commands I'll need to use? In the end would it be faster to

Hi all, I often use the following to check times and efficiency int timing = GetTickCount (); //lots of stuff here timing = GetTickCount () - timing; I get values of 0 or high value but I never seen values 1-14 One part of code fluctuates between 15

Hi all, I'm wondering if imports and includes are all done at the start of a file, or done when they are first needed?  I have a script that places an immediate buy or sell order with OrderSend, then uses OrderModifty to add stops, and finally
