When asked does it get easier to buy the dip? The answer is yes if you know what to look for. Last week I said I would love a retest of the bull flag break out at $595 on $SPY. Did I think it would hit that fast? No. Market makers do this to scare you. To take your shares at a discount. 
You can see how it touched support and bounced. Next is to watch can we make a higher high than that candle at $599.69 and then go into the gap. Next is the line at $601.8 and higher fib targets. Hope this helps.
