First, you never should feel the need to apologize for your communication skills. Doing so makes guys like me who are only fluent in one language feel intellectually lazy
As to your chart and your questions, every trade opportunity, imo, is a reversal, which is to say that price fails to continue doing whatever it was most recently trying to do or expected to do. What is most important, imo, is not whether you call it a reversal, a failure, or a retracement. What is most important to me is the simple fact of the
higher low after the test of the what I believe was the overnight low. Also, there was an attempt by the market to put in a swing low several bars back. The market broke that low but reversed immediately. This, to me, is a case of the dog not barking (I assume you know what I mean when I use that phrase - if not, ask DbPhoenix - he came up with it and he explains it much better than I).
