75 second bar period

Hi,

Is there a way to create a 75sec barperiod? I have no problem under one minute but I would like to test 75, 90, 150 second timeframes too. I read in the manual that above one minute barperiod Zorro will round the value to multiple of minutes so according that it's not possible.

You could use a 15 seconds bar period and a 5 bars time frame.

Is it possible to plot bars generated by timeframe? I think one solution can be that I record the data and save it in csv or record just the bar data and save it in t6 format.
