We always keep ourselves into triangle position and open your position only right on the trend as you see.
Each jump on trend has a reverse to its own trend till it breaks out.
At this point in the end of triangle you should stay on your last buy position and wait for the break out to reach future expected price.
Remember you will never start your deal in the middle of no where and as a good trader you should always wait and start your deal right on a valid trend.
Future Expected Price are found by orbits crashes of each main wave movement.
As a good trader you must always be aware of the opposite direction of your perspective if in case it goes to opposite direction. You will close your buy position if S1 breaks and wait till price comes on a valid trend which is most probably another Buy on S2 if it does not break.
Email me if you need more explanation about orbits and rules of trends.
