You want to find the Thursdays on which a particular script has given more than 2% Bullish Move. You select 'Thursday' in the selected day setting and put 2% in the Bullish move setting. This will mark Thursday on the chart as 'X' and mark those those Thursdays with a green arrow where the % Move was more than 2 %.
