Take a look at the MQL help file and the iOpen and iClose functions.

Take a look at a few source codes for any of the indicators you have and you'll get the idea. Also take a look at the Time[] array in the mql help file. It takes a little bit of time to study the code and check the help file but it's worth it and will help you become a better coder.

Good luck

MT4 Coding HELP!!!!

Pulling my hair out!!! (what little I have)

Trying to develop a routine that will determine what the top of the next hour is (in back testing).

EXAMPLE:

If a trade exits at 21:03 I want to trigger another trade to be entered at the top of the next hour (22:00).

The normal DateTime functions are of no value because they go by the CURRENT server time and is useless for back testing. Also tried iTime() but didn't have any luck with it as well.

PHP Code

// if there are no current orders active
   if(OrderSelect(0, SELECT_BY_POS)==false)
   {
// this is using the DateTime functions (which I know don't work)
// output of the routine will be a STRING formated as "HH:MM" (i.e. 22:00)
      string a = TimeToStr(iTime(NULL,1,0));
      string b = StringSubstr(a,0,2);
      int c = StrToDouble(b)+1;
      string d = DoubleToStr(c,0);
      string e = d+":00";
      StartTime = StrToTime(e);
     } 

Any suggestions would be welcome. Keep in mind this needs to work for BACK TESTING

Hello,

How would you get the open and close price for a given period of time? Is there a function in MT4 that does this?

For example, the open price at 1200 GMT and the close price at 1700 GMT. This info would then be used to calculate the the difference between the open and close price for that period of time.

thanks,

CFII

you could write a loop that will go back and check the time for each candle.

TimeHour(Time[x]) will return the hour of the particular candle and
TimeMinute(Time[x]) will return the minute of the particular candle.

if the hour and minute meet your criteria then grab either the open or close for that value of x by using Open[x] or Close[x].

Hope this helps.

Coding help! Hi, can one of you that is versed with mt4 coding please re-code attached script, since after MT4 (evil LOL) build 600 it does not work anymore! Plots data/vertical line, but they are somehow corrupted. This script is supposed to read .csv file and plot vertical line on chart. Csv file should be in classical MT4 format: yyyy.mm.dd hh:mm, text (any text to plot on vertical line) I have also attached example .csv file. Thank you for your cooperation, Pips with you, Simon {file} {file}

Your attached file "ModifiedPlotDataChiAspects.csv" did not resolve the problem - although data was put into 2 columns, when you save as .csv, it is actually 'put together', so to speak, and delimited with comma (comma separated value - csv).

In Notepad++, I did 'Search & Replace', removed all double quotes (") and run the script - voila, problem solved.
