I'm just showing you the max profits possible when you trade the MACD.
Notice that the moving averages on the MACD turn from red to green and at the same time, they are crossing upward.
Notice the Histogram reach the zero line(white horizontal line). As the histogram turns from RED - Yellow - green so you can actually prepare to enter the position.
Good luck and remember the rule of Risk Management - Never put all your eggs in one basket and set a stop loss no more than 2% is ideal unless you're a gambler.
