I made a post to your previous journal which I'm sure you'll notice.
As to this one, only one comment for now: don't try to force the trend channel thing. Sometimes it's obvious, and prices just fall into it. But if they don't, then the dynamic of the channel -- the limits and the median -- are of no use. So don't get distracted with it. It just adds more lines. What is more important in your 15m chart is the range that price is creating. If you set aside the prospect of a channel at the beginning of it and lower the bottom of the range to 1547-48, you'll see that you have a lot more to work with. Let the market tell you what to do and what to look at. Don't try to force price into some preconceived pattern.
