#Unfortunately , one cannot post any replies to these posts. The Buy/Sell Vertical lines look really great on my charts. My question is...is it possible to scan for these Buy/Sell Vertical lines? Many thanks to anyone who may have an idea. I am sure there are many who would like to know the answer.
