buy the dip sell gap close (SPY)

pretty simple idea. if we gap down spx and we hold some new higher daily low early on, then break above premarket close by a significant margin, the index is a buy until gap is almost or all the way closed
volatility spike still expected by end of wed, thu morning
if we gap up and start to trade up, the higher targets can be used

交易结束：到达目标:

first target overachieved take profit
