Quick question: What takes less milliseconds to process? macd_signal= iMACD (ChartSymbol(), PERIOD_D1 , 8 , 21 , 5 , PRICE_TYPICAL ,MODE_SIGNAL, 1 ) OnTick () { Print (macd_signal); Print (macd_signal+ 1 ); Print (macd_signal+ 2 ); Print

In one of my EAs i'm calculating how long a trade is open (in seconds) I used it to test if order were open for longer than a week. In such case the inclusion of a weekend was no factor. As i'm now thinking of testing for shorter periods - 2 or 3

In my EA I have a simple trigger to send an email something like this: bool email_sent; [....] void OnTimer () {    if ([no positions]) email_sent= 0 ;    if ([positions open] && [some indicator > some value] &&

Something is off... I've tested my EA before successfully, but now it does not work. The value for the CCI is always "0".    cci_long= iCCI ( ChartSymbol (),cci_timeframe[pos],cci_bars, 6 , 0 );    Print ( " CCI_long = "

I have a weird one below: The if statement should only be able to return 'true' on Fridays , yet i have this trigger every day for some odd reason and positions close as a result. void OnTick () { <snip>    if (TimeHour( TimeLocal

Yesterday's upgrade to Win10 Pro version 1511 OSbuild 10586.17 seems to have wrecked the compiler! (I have MetaEditor 5.0.0.1218 ) Cannot compile anything and continue to get "EX4 write error". Starting Editor in compatibility mode doesn't help

Having problems with customer set inputs. i read: https://docs.mql4.com/basis/variables/inputvariables  but i cannot get it to work. this is what i want to do: simply create long/short as part of drop down box during input... #property strict

I have my EA protected for a crash by means of a file (crash.bin). While running the EA it writes the crash.bin file every 30s, and it holds important data for when having to recover. If the EA is removed on purpose then the crash.bin file is deleted

i have the following simple code for an OnTimer() function:      void OnTimer ()   {    int bla= FileOpen ( "last.txt" , FILE_READ | FILE_CSV , " " );    if (bla== INVALID_HANDLE )     

Hello i'm looking to run a BAT file from a script (and upon successful testing ultimately from an EA). I've looked at  https://www.mql5.com/en/forum/139191  which i found very helpful but... #property strict #import "shell32.dll" int

Say i have a file: "DOWJONES.txt" the file is updated from time to time through email scripts whenever the file is updated, it needs to be read by an EA and the new values must be loaded. FileGetInteger() can tell me if a new file is present by

Someone asked me an interesting question: Is it possible to Hide Outside Trading hours? So if you show DAX, that only bars during Frankfurt trading hours are shown and rest of data is discarded - that is: price is moving , but no bars are formed. I

I'm using the 'while' statement with great success for some recovery work. Embedded is a counter (for # of tries) and after such # of tries there are checks/balances before looping back to the counter such to ensure things don't take too long and

I have use FileWriteArray() succesfully in multiple EAs, but this time it just writes "0"s  - or it doesn't write at all, despite the msg: File Write =OK. As i'm using the exact syntax i used in other EAs i'm really puzzled and after a couple of

I throw a lot of info on the chart in my EAs and would like to organize that a little better. To separate values I now go about it as follows: string text; text= StringConcatenate ( "tic= " ,tic, "    tac= " ,tac
