[R-SIG-Finance] qantstrat same period execution

[Ulrich Staudinger]

but in direct response to this mail, i think that assuming to get the
close price at days end is very dangerous. in some markets the
reported close price is calculated on an aveerage based on trades done
in the  last ten minutes. while this is just a stronger argument for
end of current period execution, it is also built on a highly specific
fact. and, when the market is closed it is closed, unlike intraday
periodicities.
