I prefer to read charts and shortlist. Later do further analysis.
Major benefit of this approach is, you gain experience and will be able decide when to BUY/SELL a stock, with increased accuracy. Also you can identify stocks for trade early.
With practice and being in touch with charts, you only need 10 seconds per chart on your set up for preliminary scan. It is not as hard as it initially feels.
I started this approach after NB Sir encouraged in a live streaming(long ago), to see as many charts as possible, everyday.
