How do calculate Angel ?

The rest is up to you (the what price and time to use and the how to use them and what angle you wish)
But the easiest way is to use a linear regression channel and you will not have to do any of the stuff (like calculating angle, which is imposible using financial time series) and you shall always have a perfectly fitted channel made of parallel lines
Time3 point should be parallel to the Time point. What ic calculate Time4 and Price4 Point.
Some problems :
1. how would you calculate the "angle"
2. angle in financial time series is meaningless (you can not use price changes and time changes to calculate "angle" - they are completely incompatible)
