930minute option to timeframe

Hello - Please add a ‘930 minute’ option to the dropdown for timeframe selection. Reason is that currently there is no ability to split the RTH and Pre-RTH sessions for futures. 930m breaks down the day into two candles - 1) market open at 6pm ET till before US cash open at 9:30am ET 2) after US cash open until market close for the day at 5pm ET. Atleast it will enable us to differentiate the activity between low volume and high volume sessions of the day. Hopefully this can be done quickly than providing ETH/RTH toggle
