I used Sierra charts and I have been trading the 6E , I m trying to set up my market profile on the sierra for the 6E staring time at 7:20 Chicago time , I went to custom sub period 1 start time 07:20 and end time period 1 07:30 and custom sub per. 2 time 07:30 to 08:00 am , works perfect for the first 40 minutes or until 08:00 but after 8:00 I m getting my 30 minutes profile on 08:20 to 08:50 , 08 50 to 09:20 so on anybody know how I can fix the problem ??? thanks

You don't need to use custom sub period to achieve what you want. You just have to open a chart that has 07:20 as a start time (in the Chart settings).

When you add the TPO-indicator to your chart, you scroll down to the setting "30 minute letter/block subperiod handling" and select "Start new subperiods at even 30 minute time blocks". That should create a first TPO block or letter for the first 10 minutes and after that a new block or letter for every 30 minute period that follows.

Hope that helps.
