there is one type of trader that is not there that is a 'momentum trader'.
I will stay in a trade as long as there is still momentum in the move whether it be long or short.
I've done a lot of reading of the work of WD Gann. He always talks about time price. Basically saying that everything that goes up must eventually come down....(or go sideways sometimes with quite a lot of volatility as we are seeing at the moment)
If a stock option currency or indices moves quite rapidly up in price over a period of time then that stock option currency indices or whatever must go down or at least go sideways for a similar amount of time. So it is time catching up.
How many times have we seen a strong break out bar on a stock by strong I mean a larger than average size bar in strong opposite thirds only to find that the stock has retraced rapidly over the next few days before the move decides to take off again.
I know I use to always get caught by that.
Similarly he...(WD Gann) also talks about what he calls form reading that is the size placement of the open close on a bar. He says that as a move comes to an end the bars become weak showing that the move is coming to an end basically the buyers are no longer prepared to raise their prices. All this in conjunction with direction angles of moving averages that measure the overall momentum of the particular stock or what ever.
Anyway for what it's worth there is a free website that has video tutorials on this at
