hi guys, thanks for your interested in my thread
the open price method, based actually only on M1, just uses one price every minute, totally ignoring all other ticks
that's the reason of the really different number of ticks modelled
but when i use full tick data, in my mql4 i force to use always the same opening price of a new bar (simulating the open price method also using tick data fxt)
so, even if number of ticks is greater, i'll only use one tick value for each minute
1488015 is about 30 times smaller than 47378401, but with almost identical results
it means that we were using 30 times bigger (and about 30 times slower) file for backtest... not needed!
the faster speed in backtest is totally due to this new approach
i limit usage of my EA only on the first tick of every minute to do all calculations, instead of each tick
i hope tickstory developer team will now consider my request...
