How to change indicator lookback period to market open

  I like this indicator, but instead of a lookback period, I would prefer to be able to start at the American market open (regular hours, not extended).  Is there a way to do this? thx

  Also, in regards to the STD DEV indicator above, can it be adjusted to calculate on last candle close?

  Currently, it wiggles with the live candle, and I would like it to not do that.
