Is there a way to express as a condition where price is above the volatility stop and the low for that bar was below the volatility stop?

There isn't a way to do this using a formula. It is possible to click on price and select Create Scan Condition to create a condition for price being above the Volatility Stop indicator.

Creating a condition for the low being below the Volatility Stop indicator requires an extra step. You would need to add a 1 period simple moving average with the Average Of seting set to Low to price. You would then be able to click on the moving average and select Create Scan Condition to check for the moving average being below the Volatility Stop indicator.

Add both conditions to the same EasyScan to combine the conditions.
