One of the most important errors that traders make with regard to charting -- whether they are fundamental skeptics looking for "proof" or newcomers to charting who are interested in developing and improving their skills -- is dwelling on what happens after the point of action.
Granted, the serious student of markets will want to examine and analyze his trades so that he can improve upon his strategy. But that is not quite what happens in actuality. What happens in actuality is that the trader, at the point where he would ordinarily act or is required to act, thinks not of what is in front of him but of what happened the last time he was in a similar trade. For example, if he sold the last time and watched the stock bounce and resume its advance, he thinks that the same thing may happen this time and holsters his gun, even though his current and applicable strategy tells him that he ought to sell. At that point he's trading not on the basis of strategy but on the basis of hope. Whether the stock does in fact rise or plummets to its daily low is beside the point.
In this regard, whatever happens after the trade is closed is irrelevant. All that is relevant is the strategy, and one must be able to approach the stock fresh as soon as the trade is closed. In order to do that, one must be able to look at what is happening now, not dwell on what happened in the past. Only then can one even consider re-entering a position in a stock which he sold perhaps minutes earlier.
One may make three or more entries in a row that don't work out, but he must be willing to re-enter at the first sign that conditions are right according to his strategy, even if those conditions present themselves almost immediately. That may seem like a lot of in-and-out, but that's trading. If one feels that he is over-trading, he can simply stop and watch, observing the action without emotional entanglement. He may find that he shouldn't be in the market at all.
He may also find that he's just not suited for a timeframe so brief and that he's more suited for a longer timeframe, though the patterns he requires for entry -- such as a base or double bottom -- may not exist in a longer timeframe, just as daily patterns often disappear in a weekly chart.
It all comes back as it always does to keeping it simple and knowing oneself, even if that means knowing oneself only well enough to determine that one doesn't want to mess with any of this. Anyone who doesn't want to make the journey has plenty of funds to choose from.
