not sure if you can paste em in, i thought it was based on 100 that you follow each day. i haven't used esignal for years, but when i did, it was only limited by max number of charts. i use ensign now, and i'm not sure there is a max number. i believe its limited by RAM. you would have to type the symbols in the first time, and then it would save them all of course. if you follow say the 100 most active each day, then no, i don't think this would work. just so i understand, do you wish to do some sort of screen each day, and then get charts on those symbols vs following the same 100 each day?
I would do a very loose screen (based on liquidity for example) that will give me say 200 leading stocks. Then I want to see the chart of each one of them, and look for pullback or breakout setups. When I single out say 20-30 stocks that show these setups, I will watch them in real time to see if the setup is triggered and I have to take a position.
