algorithmic trading - How to setup a period of time in an MQL4 source code? -


i using mql4.

currently, using [expert advisor]-s in mt4.strategytester, , set period-of-time build-in pull-down calendar gui-elements.

what want setup period-of-time straight in mql4-source code.

if realized, example, can compare result 

'from 2011/01-to 2011/12'

to

'from 2012/01-to 2012/12'

and on.

there easy solution requirement, added value automated, large-scale hyper-parameter optimisations inside said mt4.strategytester tool, using proposed pair of parameters ( astartfromdate , aruntilldate ) as iterable tuple, harnessed tradingstrategy robustness cross-validations of release-candidates on sweeping/sliding calendar window-of-time.

extern datetime astartfromdate = d'2010.01.01 00:00'; extern datetime   aruntilldate = d'2345.01.01 00:00';  void ontick(){      if (  time < astartfromdate         || time >   aruntilldate            ){            ignoreticksoutsidethegivenperiodoftime();            return;      }   // sure inside given ( mt4.strategy/tester iterable ) period of time      ...      ..      . } void ignoreticksoutsidethegivenperiodoftime(){   // ignore, still may execute utility service during void run }

be careful on different scopes of syntax support:

one might cautious on use-cases, include strategytester restrictions of powerful new-syntax-constructors:

a printformat() being 1 of such un-supported pieces inside strategytester during hyper-parameter optimisations.

printformat() function not work during optimization in strategy tester.
