Maybe someone can help me out? I am searching "Standard Deviation Channel indicator" or "Linear Regression indicator" but have not found "right" one.
The indicator what I search is In TOS and it is called "StandardDevChannel"
I have searched those indicators and found some but the calculation it's not like in TOS. In TOS you can use it one day basis(charting:Today only), it basically draws a channel even it has one bar for calculations and when the time goes on the new calculation goes in. But indicators what I have found calculates based on historical bases. They can't calculate from market open and one day bases. I would like to see one big channel based on 9:30am to 4:00pm market range.
Hopefully you understand my explanation?
How complicated is to modify TOS indicator for Tradestation?

Please help if you can.
