OK, thanks a lot for this, very insightful.

I thought that the LOOKBACK period only had an impact in TESTMODE with a specific StartDate.
So, in TRADEMODE, this basically means that it's best to only re-start Zorro during the weekend when it's really needed, because live trading is always idle for the length of the LOOKBACK period, even when StartDate is 'NOW'.

Is this correct?
