Identifying Impulses and corrections

Herein is a simple way of identifying motive/impulse moves. The motive moves are where the price is moving sharply in the direction of the trend. Price thereafter starts struggling on the opposite direction and then continues in the direction of the motive move.
Looking at the MACD indicator we expect the price to correct from the current point until it comes close to the trendline.
