Quote from joesan:
Is this tradestatin chart of k200 collected with backfill from IB or you have to keep tradestation open during the whole session of k200 ?
Still can not get chart for k200 on IB TWS chart, everthing from this Monday is missing.
I leave my thing on except a couple of hrs after the US close. So i guess it is possible the historical backfill is not available.
