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?

Based on what I read in the manual, it seems best not to define StartDate at all in TRADEMODE. Quote StartDate = NOW sets the start date to the current day, and executes the run function in [Trade] mode immediately after the lookback period, regardless of the current time. Useful for strategies that do not run permanently, but are only started for modifying a portfolio. - StartDate = 0 (default) starts the simulation with NumYears before the current year.
