I am new to Dukascopy and not quite understanding the properties and methods of the various objects used to code trading systems.
If anyone could assist my understanding by translating the following pseudo code , it would much appreciated:

If Market Hours > 9 am but less than 10pm, then begin:

If % change (90 bars, close price) > crosses under a Threshold AND (NOT ( % change(100 bars, close price) crosses under Threshold))
Then buy High (Last Bar) on Stop
End
End

Thanks
