Similar to methods that have 2 versions - without filter and with filter:

getBars(Instrument instrument, Period period, OfferSide side, long from, long to)
getBars(Instrument instrument, Period period, OfferSide side, Filter filter, long from, long to)


Please add method overloading where it is needed, like here:

getBar(Instrument instrument, Period period, OfferSide side, int shift)
getBar(Instrument instrument, Period period, OfferSide side, Filter filter, int shift) <--- MISSING

getTimeForNBarsForward(Period period, long from, int numberOfBars)
getTimeForNBarsForward(Period period, Filter filter, long from, int numberOfBars) <--- MISSING

getTimeForNBarsBack(Period period, long to, int numberOfBars)
getTimeForNBarsBack(Period period, Filter filter, long to, int numberOfBars) <--- MISSING

getPreviousBarStart(Period period, long barTime)
getPreviousBarStart(Period period, Filter filter, long barTime) <--- MISSING

Greetings.

Methods getTimeForNBarsForward, getTimeForNBarsBack, getPreviousBarStart implemented as simple calendar calculations - they don't take into account trading breaks schedule.
You can use com.dukascopy.api.IHistory#getBars(com.dukascopy.api.Instrument, com.dukascopy.api.Period, com.dukascopy.api.OfferSide, com.dukascopy.api.Filter, int, long, int) method to load necessary number of bars and take time from corresponding bar.

Method getBar(Instrument instrument, Period period, OfferSide side, int shift) determines time of requested bar in the same manner, therefore it also can't use Filter.

Regards.
