market price movement is a simple one:
the basic movement is two legs.....this happens on all time frames and inside time frames.
after two legs is completed that becomes [or should be taken as,] one leg, and so after a correction,to the before mentioned two legs movement, the second leg will start, which will be as long in price or time,as the first two legs.
so each 2 leg move becomes bigger and bigger with the counter trend move becoming longer
this continues and that is why trends last and last until it just blows itself out
to see it on historical charts charts, is the easiest task.
To see it happening on live charts,usually takes considerably longer, and is genius.
To trade it is master class trading.
