Disliked.....after the 2nd candle opens outside the buffer zone.
....If later on that day or the next, the market takes the price back into the same CZ and it "breaks out"of that CZ again, do I trade that CZ again?
A1: I wait for 2 candles to close outside the buffer zone, not just cross it. The 2 candles can be any color, but they must both close on the same side of the same buffer zone line.
A2: There is no rule here. I have no idea what TF or what pair this might be, so how could I answer you? Think about it. This answer is totally up to you and how well you feel you know your market at that singular moment in time. Your decision will be based on your total body of experience, combined with gut instinct. Nothing I say today will have any effect when that moment comes, nor should it. When you can make these decisions on your own, and feel good doing so, you will have become your own teacher.
To improve is to change. To perfect, is to change often.
