Hello,
I recently downloaded the Order flow indicator 1.7 free version and imported to most recent version of NT8. Instructions were followed when attaching the indicator to a chart. The indicator seemed to work but also caused problems with other indicators that comes with the platform. I have the Tool Tile indicator that comes with the platform loaded in other open charts. The Chart with order flow only had the order flow indicator loaded. The problem occurred when I tried to edit a line drawing in another chart. The platform would not accept any change to properties of the line(change color,style,etc.). I removed the Order Flow indicator and restarted platform and problem went away.
