i think its more flexible if 2014 means until the END of 2014. If u take the actual year for example and u say "EndDate = 2017;" and ur strategy trades from date X until NOW - then its more comfortable (as it wud have been, if 2017 wud stop at 2017.01.01). So u wud prefer to use "EndDate = 2018;" in that case? i rather think so, cause it wud be "kind of confusing" wink
