I am concentrating the day trading on "three "quintets", the Q, mentioned in the header, five semis and five bio. On top of that I have few other stocks like COCO, BSTE and PII which I swing trade, and then I have a core which I get in when I think the market risks are lower or the prices are "good". After trading a stock for some time, one memorizes the entry points both for medium and short daily swings, but real time charts are helpful to select entries as well.
