I think I see what you're saying. If I bring the trendline up the angle will be steeper though, because the line should touch the second bump on the way down. If the line becomes steeper, then our current position to me is that we are out of the downtrend.

The true break will be above 17.5c . There should be a horizontal resistance line at 17.5c on my chart and was going to add it, but thought to show the simplest form of the chart. I see the downtrend resistance line as very important.

It's good to be conservative and add extra lines. I do that sometimes too in order to not get overly excited. I personally like setting my trade up, and letting it do it's thing. In the meantime I check my analysis, but also look for other trades and spend time on my other hobbies. Sure if the pattern breaks it's a sell.
