  • VIX known bugs: (fixes are in progress)
    IV, IVRank and IVPct values are not accurate and sometimes has missing values.
  • SPX Root change:
    Due to regulatory changes in SPX the positions initiated before and held after 2017. 05. 01. is wrongly modeled. The position will exit as if were prices were all 0.
    Workaround: Exclude the given date from the backtest by splitting up the time period to a before and an after part.
  • Account variables during Entry.VarDefine setting:
    The account variables are not available during the Entry.VarDefine setting.
    Workaround: Schedule an UpdateVar event after entry to access the respective variables.
  • Variables in ExitPosition TradeEvent:
    The variables stored during ExitPosition Blotter Event are reflect the last known state when the legs were on.
    Therefore, the reported price and pnl values are excluding slippage and commission.
    Workaround: Incorporate slippage and commission via Exit.VarDefine settings.
