Can we still get to have a custom period selection for historical testing?, detecting it automatically is good, but sometimes you need to see it working on lower timeframes.

He means custom periods for bars, eg, 7 minute charts, or 23 minute charts.
I haven't looked into whether there's a mechanism for feeding charts, strategies, or indicators your own custom bars. I'm guessing it isn't doable right now, I couldn't even find a way to instantiate a bar object in java; the API only exposes the IBar interface. When you try to use (reflection?) in java to get the name of the type you have a handle to when you have a handle to a bar object, it is some weird class name like: com.dukascopy.api.something.somethingelse.a.g.b.c.a.e.b
However, ignoring those concerns, generating data for custom periods is easy. 7 minute charts = 5 min + 2 min. 23 minute = 15 + 5 + (3 1min bars), or 30min - 5min - (2 1min).
