jcl,

I'm assuming that the lowest granularity of tick data is the 1 min OHLC and that that bfleming doesn't use actual tick data.

In that case does the TICKS flag mean that zorro evaluates all trading at each 1 min OHLC irrespective of whether BarPeriod = 60 or 240 and irrespective of the Timeframe used?

or would the BarPeriod at 240 use a 120 min OHLC and at 60 use a 30 min OHLC?
