I actually use a 3-min bar chart, and a 15-minute to look at overall trend. An example of a trade would be this:
I will keep staying .06-.07 off of the inside bid w/ 1000 ,06 off, 1000 .07 cents off, and 5,000 .08 off, 5,000 .09 cents off. As the stock is on its dip, I watch volume to make sure there isnt a reversal taking place as I start getting hit, I will watch see market maker action (example, if MLCO is a buyer, do they pop back in on the bid and if so where), as the stock starts retrending, lets say i know am long 6,000 I will start covering, 1,000 .03 higher, 500 .04 higher, 2500 .05 higher, if im getting hit, Ill let the rest run and possibly add to it on the next dip or just keep a trailing stop.
its classic scalping, the only time Im really relying on the technicals is when I am looking for reversals of the immediate trend.
I know this isnt totally clear, especially if your not experienced. alot of this relys on having a feel for what your trading as well (the unexplainable aspect of trading...the "intuitive" part, that is what i tink is one of the most important parts of trading).
