MQL4 - FileWrite not working in strategy tester

Hi.

Looking for a bit of help with some code.

Like the title says, I can't get FileWrite to work within strategy tester. The code works just fine in an EA attached to a chart and outputs as expected but run the same EA in a strategy test and.....nothing....no file even created in the MQL4\Files folder.

It is very basic code, simply open file, output and close file.


Can anyone tell me what is wrong? Is the file created somewhere else?

Look in the "Tester" folder

Oh obviously, in a completely different place!

Found it! Thanks for the tip, I can get on with what I was doing now.

Hi, I am developing a mql4 indicator which draws line for all the body high and body low of all the candles. Plus I have created a function to view any timeframe's body hilo line in the current chart but it is not showing the correct lines, example, if I am viewing H1 body hilo lines in M15, it will draw the lines depening upon every 4th candle of M15 candle(4 M15 candles = 1 H1 candle). Can someone pls correct it, I will be grateful.
PS: I am a newbie
Here is the source code

Also, if someone has a mt4 indicator which creates a trend line joining the current price of the symbol that is being viewed with the open price of the current candle of any timeframe which can be viewed in any timeframe. Like I am viewing the chart in M15 and want a trend line joining the current H1 candle's open price with the the current price. It would be really helpful, thank you.
