wedges in channel's! how to predict the trend channel's

in every channel's there are wedges forming while the trend is reaching a support or resistance line(blue line) P.S I draw that line 1 year ago.
with getting close to that level we can see that the market is going to loose energy that's the time we must open a position or close it(red number 3 in the chart was a good time to close long that's what I did)
