Personal Criteria Formulas and EasyScans always use the twenty-minute delayed Daily data. This means you would need to use Indicator Sorting to do any of the following on 10-Minute Charts.

Sort by indicator or price movement using Visual Change sorts
Sorting price and indicators by their Actual Value
Real time indicator sorting (available at the Platinum level)

Let's say you had 20-Period Donchian Channels using the following formulas:

Upper Band:

MAXH20.1

Lower Band:

MINL20.1

The wouldn't necessarily turn up at the same time. You could find out if the Upper Band was increasing using something like the following:

MAXH20.1 >  MAXH20.2

You could even "predict" tomorrow's direction (since Donchian Channels normally use the previous Highs and Lows) using something like:

MAXH20 > MAXH20.1

The Lower band would just require replacing MAXH with MINL. It would also be possibe to calculate a Centerline:

(MAXH20.1 + MINL20.1) / 2

If you did so, the formula for the Centerline increasing would be:

MAXH20.1 + MINL20.1 > MAXH20.2 + MINL20.2

You can't make a Personal Criteria Formula to monitor a 10-Minute Chart. You need to use the formula in a Custom Indicator (if it is value based) or Custom Percent True Indicator (if it is Boolean - returns True or False) and use Real Time Indicator Sorts on the Custom Indicator or Custom Percent True Indicator.

You have to choose Add Indicator | Custom | Percent True.
