My 2 cents on daytrading.
The reaction time in daytrading is very very short; you need to react fast. If you are using too many indicators and comparing and confirming them, you can not react fast enough. Therefore use just one indicator and understand it thoroughly.
Now, I will outline a trading system ( not mine ) that I have used successfully.
You must trade with the trend. Use 50 period Simple Mov. Avg. to determine trend. If it is sloping upward trade from the long side and vice versa. If it is flat, stay out.
I use 10 and 20 period Expoential Mov. Avg. for entry. Wait for price to move between these avg., then enter the trade. You can use candlestick to refine your entry. Doji, hammer, piercing pattern for long entries; doji, shooting star and dark cloud cover for short entry. After you have used this technique for about 3 entries, you may want to wait for a larger pullback to the 50 SMA itself and enter the trade there. Quite often the trend is so strong that it will not pull back to 10-20 zone. That's where I use woodie's CCI pattern called " Zero line reject"; it will put you in the trade if you are not getting the pull back to 10-20 zone.

To gain an early entry, you may have to look at classic chart pattern. I have found the rectangle to be the most reliable. You can use breakout from rectangle to get an early edge.
Confine yourself to 2 or 3 markets. It is ideal for index futures. You can use it on some highly liquid stocks with fair volatility.
I hope I have been of some help. If you want to use this system, paper trade it for a while and see if it meets your need; if it does not; well through it out, it didn't cost you anything anyway.
Happy trading,
