Is there a difference using PERIOD_15 instead of its integer value 15 ?

 
I refer to this post 'EA Tester is useful?'

and the irusho1 reply telling:

...
3. hardcode your timeframe in tester (i.e. use iTime, iHigh, etc. use explicit PERIOD_?? instead of 0 or Period() function)
and run your EA on 1 minute frame only)
...

1. Why is this point important to get a test closer to real life ?
2. Is there a difference using PERIOD_15 instead of its integer value 15 ?


Does this forum allow to contact another member ?
If so, how to do it ?
Thanks
 
PERIOD_M15 is the same as 15, it is a symbolic defintion of 15.

sometimes M1 period gives more close results to real time than larger timeframes.

Also in real life hardcoding your timeframe will allow you to watch your chart on any timeframe without effecting the running expert.
Most often specific experts run on specific timeframes anyway, so hardcoding timeframe is actually allows less chance for error by putting EA on a wrong timeframe.

And there is no need to contact me since I use ESP to know when they leave messages for me :D
