Here is a recent chart posting by a scribble student. Note that the forecast is for price to go one of two ways, either up or down. In addition, analysis of the upper trendline and lower trendline show that they are drawn in an arbitrary fashion. This is because they could have easily been drawn at different angles with the upper line going on top of the 105.61 bar and then across the top of the 109.17 bar. This would greatly change the angle. In addition, the lower line cuts through the noise at the bottom instead of being on the outside of the 89.70 bar. This would greatly change the size of the range and could show a much greater potential for price to fall. Furthermore, why isn't the lower line touching the 99.52 bar or the 99.13 bar? Conclusion to be found here is that the trendlines can be drawn however one feels they need to make the noise fit the way that they want it to.
The conclusion is that you don't realize this is a weekly trend channel, which is why the lines occur where they do. The trendlines and resulting channel are drawn exactly as they should be.
What is of import though is what is happening now and that can be determined by better methods using indicators along with price action and then adhering to strict and prudent money management principles.
It's all in hindsight so it doesn't matter anyway.
Which is the chief difficulty with your approach: it's all in hindsight. Show somebody how all this works out in advance, not by looking in the rearview mirror. Problem is, you can't. You can only boast about what was. Or might have been.
