Yes, I believe TA forms the basis and structure for potential trade setups. Unfortunately a TA swingtrade setup can be easily derailed by something unexpected like a change of broker rating or by strong institutional buying or selling, blowing through stops. This happened to me twice in two days on two different stocks. At that point, the ony thing to do is exit, stand aside and possibly reverse positions. But I was too slow on the trigger in both cases to reverse. I've heard that institutional buying/selling is a large proportion of the market (60 to 75%??). Analogous to standing in front of a freight train if it decides to move. In these cases, I would like to train myself to get on board instead of getting run over. Does anyone else use reversal of positions when their stops are blown, or do you just go on to another trade?
