Realizing that of the many diverse profitable trading styles(those with an edge), that one might utilize, each must be personalized to fit one's individual personality and emotional makeup in order to work. Trading is mentally challenging enough, not to have a misfit system to add to the mix. My trading style has consistently been for many years to take as much of the large id back and forth price moves from a handful of liquid yet volatile big cap NASD names. I will get on one stock for weeks on end until it's characteristics change for the worse and 'play' that stock both ways each day but realistically lean one way depending on mkt and stock trends. I feel a need to know my vehicle as much as is possible in order for me to be aggressive in taking my albeit simple signals. I feel momentum trading(which i essentially do) is NOT dead, its just that stocks don't trend in one direction for long of late. But the individual id moves are still great. Most complaints to the contrary, i feel, are due to not aggressively trading a system you believe in. When daily volatility slows, i get more disciplined and reduce size, and when the reverse occurs i hit it. Experience helps, but we all must start somewhere, it will come ,believe me.
