You can compare a bar's price data such as checking for a higher close. The following is an an example and represents one of many possible combinations.

1. Expand the "Price data" category and select the "Close"

2. Select the ">" (greater than) relational operator

3. Expand the "Price data" category and select the "Close"

4. Set the "Bars ago" parameter to a value of "1"

Once the "OK" button is pressed, a condition is created that would translate to the following:

"Current closing price is greater than the closing price of 1 bar ago"
