How to code to refresh a tick chart to a new tick bar size?

08-20-2021, 09:14 PM

I am looking to:

1. find the total number of ticks/trades in the last day on a 1000-tick chart
2. divide by 60,
3. then refresh the tick chart to the new tick value, so the tick chart shows exactly 60 bars per day

How do I start on #1?

For #3, writing BarsPeriod.Value=2000 in OnStateChange on a 1000 tick chart doesn't do anything - the chart is still 1000 tick.

Thank you for any help!
