Trading will not likely be as simple today as it has been. Price exited the trend channel but moved sideways thereafter. It must at least hold here if not progress, otherwise buyers (who are currently weak, the strong having bought at the bottom of the channel) will toss their shares back on the market and price will return to the trend channel.
It is particularly important, then, to look for confirmation or contradiction of your "biases" or trade hypotheses at each turn. Those who have fear issues assume that every move counter to their trade is a red flag and a harbinger of doom. As unrealistic as the expectation may be, they want each bar to move in the desired direction, one after the other. Thus a lot of exits, a lot of breakevens, a lot of commissions, a lot of missed trades. Focus instead on the fact that retracements are an opportunity for those who missed the proper entry to take advantage of the second chance (or third, or fourth, some jumping in all the way to the last retracement before the top or bottom). One must ignore the "bar" per se and focus on what traders are doing and how they're doing it. Is price, for example, plunging (after an upmove)? Or is it pausing, the result of light selling (sellers can't be too aggressive or else they won't get the best price)? What matters, then, is not the move itself but the character of it and the extent of it. As with yesterday's upmove, if price doesn't drop below the last swing low (in the market), or if it drops below the demand line (in the trader's head) by a couple of ticks but then rapidly recovers, then the upmove is intact. If, however, the trader is obsessed with his entry and where price is in relation to it, he will in effect go blind and be incapable of assessing the situation properly.
Sufficient observation will make this clear, but the longer the trader has been trading, the more difficult it becomes to observe without focusing on entries and couldawouldashoulda. But then if it were easy, everybody would be doing it. Fortunately, though it may not always be easy, it is usually very simple.
