The second lesson is obvious but should be mentioned. Not all days will be trendy. Today was range bound. So trade accordingly. In then out then reverse. Then in and out. On trend days you can hold for a long time. For example, 12/29/2017, I put on a NQ short trade near the open and held all day til the close. Not all days will be like that. So gotta be flexible and constantly monitoring price actions to see which kinds of days it is and trade accordingly.
Lesson #3, even though the entry pattern might show a particular bias it pays to wait a little before entering to see how it unfolds. I was about to enter a position then I paused just for a second. Then I see it evolving. And it was not the original pattern I thought. So I saved myself. Even if I had put stops in, sure it will have cut losses. Why cut losses when you can avoid it all together?!
The next level of improvement would be once I see that it's not the original pattern(long or short) then I should go the other way. So for example I thought it was a short pattern, pause to see(seconds), then when it showed to be a long pattern, jump in and go long.
