B,
If price is trading in a channel, for the sake of argument, lets say a downtrend channel, expect it to bounce up and down with a bearish tendency. Now, to ensure your stops are small, even in a downtrend you want to short high, and in an uptrend you want to buy low, this is where the trendlines of the channel help. This is not the same with formations, a solid confirmed reversal formation is quite alright for entering at the lows but this is not the case of channels. Hence why I suggest the trendline channels usage as guidance. The formations price will form at the extremes do tell good info, so make sure you pay attention. In yesterday's case the downtrend channel formed a bear flag as it broke the channel to the downside, I was almost certain price was ready to fall, but it failed miserably. Naturally I took my small stop and realized that price was not ready to go to lower lows because if a confirmed bear flag failed, which is one of the most reliable formations for downside, the failure should be applied accordingly. The subsequent move was higher lows from the bear flag pattern until it finally broke out of the channel. However, that was predictable. As explained in the past, failures are sometimes as powerful or even more powerful than patterns themselves.
Notice that during rectangle consolidation, where price is bouncing off support and resistance there is no predominant side to choose between the two, in this case, look at the whole day and choose the side that has been winning all day long, if no clear definition, simply stay out and wait for better setups or wait for a confirmed breakout that aligns with the predominant intraday trend.
