There are several things going on as you monitor, not all of them being helpful to you. When you are sidelined, the unhelpful things do not come to the forefront as you look for entry. Once you are participating, the unhelpful things crop up as you monitor for exit. They show up as fretting or fear or some other. When you are able to look past these things, usually during a debrief after the trade is over, you may see that your "rationale" for taking action had little to do with your knowledge and skills about trend. The exercise was just a simple way to show what you were sensing and analyzing before you decided and acted. The exercise was made possible because you organized yourself in a way that allows for you to debrief effectively.
With regard to the second part of your post: Rockets fail and rockets sometimes "work". Price trends do not strictly follow the rules of "rockets" or any other indicator setting as laid out by any person. The rocket is a device by which a skilled person can relay to an unskilled person learning unsupervised that "this is a low risk time for a beginner to be participating." All such devices are limited and perhaps doomed to fail to achieve their intended purpose for the reason that it may not be possible to define a low risk situation for a person with no skills trading on his own.
In any case, I believe that making money solves all problems in learning to trade. What a person learns by making money defies explanation with words. By "making money" I mean growing your account through all kinds of errors and tribulations. I use a simple benchmark: trading the minimum, grow your account to 3x, where x = initial capital and no greater than twice full margin for one contract ES (roughly $8000). There is no time limit in which to do this.
As a venue for transference, ET, and the internet in general, is very limited. Nonetheless, I think enough has been made available over the course of years for a person to get started. You are definitely way past the beginning stage and I think you need no recommendation as to how to proceed at this point.
