Hi,
I've searched the forum but I didn't found a clear answer (or didn't understood it

).
Just one question... My strategy uses fixed times to trade the London session.
If I backtest the strategy on a few years with the tester, must I change automaticaly my GMT trading
times according to DST ?
This means, for London time, using GMT for winter and GMT+1 for summer time.
I'm a bit confused because I don't know if historical candle times are matched to
actual JForex time on the top right or have their own time no matter what's the current time.
Thanks a lot.
