The results of contest backtests seem to be different then using then running a backtest with the same dates independently, and by a large factor. I see there was a glitch months ago that caused the same error and I was wondering if it still may exist. Or it may be my commission and slippage settings which are:
set_slippage(slippage.VolumeShareSlippage(volume_limit=0.1, price_impact=0.0))
set_commission(commission.PerShare(cost=0.001, min_trade_cost=0))
If the contest settings are different that would explain a lot, otherwise I am confused as to what the problem is.
