Theres generally 2 ways to earn from price movements.
First way is trading along the major trend. By entering and aligning your position with the big tide, you can sit tight and earn huge profits easily. This is the recommended way. Catch is you need patience in sitting tight for the full move to play out.
Second way is when prices move too deviated from its mean, price usually snapback to its norm. Or market sideways and prices whipsaw. This kind is countertrend/hit-and-run. Discouraged. You can earn quick profits. Lesser. And more likely to lose.
