Scalping for pennies is very random and complicated, therefore you must have a simple strategy to capitalize on very fast and quick movements. Commissions must be as low as possible.
Tape reading, I don't personally use, but others have told me it could help determine entries.
Also depends on the number of trades you make a day. I average around 30 trades a day waiting for high probability set-ups, but others make 50 - 100 trades a day easily.
I just look at price and follow it. I also use support & resistance and a few moving averages.
Keep it simple, execute, set your stop tight and take your profit when you should, but don't be afraid to let winners run, letting winners run is something that I have to do myself, because I've cut off potential profits, where I have taken 10 cents, and the trade could have easily gone 50+ more cents in my favor if I just held on. But you have to develop a simple system and stick to it and execute it and have quick execution and be able to think quickly.
It's hard to learn, but even for me, now I just wait for my set-up and take it and just react. It was emotionally challenging when I first started, but when I let go and read books on psychology of great traders, it became much more realistic and it allowed me to execute easier, not to say that it is easy to trade, but if you have a system and can stick to it without or at least have controlled emotions, scalping can be a nice way to trade with very limited risk.
I wasn't around when it was fractional based, but from the traders I talk to, a lot say they liked it back when it was fractional, it was easier to scalp for bigger profits. I don't know personally, but am ok with the decimal system, I just hope they don't switch back to factions or something strange like that.
Good luck
