A Climatic 'V' Position

A very powerful reversal happened this Friday's market, especially for the Dow and the S&P as shown from this 15-minute chart. Notice the  hard drop (catching the falling knife) that originates from the Globex (overnight session) till the first hour or so from the open. A powerful 'v' (position???) formation emerge that turn the tide to the bull side. Catching this kind of trade is the best opportunity even in the middle portion of the trade. You don't need to catch or buy the low (deep) and sell at the top, just trade the middle portion is the best trade to make a gain, as the famous Bernard Baruch profess, 'I made my money selling early'. Just ride the 4ema (the blue line) and you will not go anywhere except to the bank!
