I was near Albany, NY when the flash crash of August 24, 2015 hit. I was on my way out to a retreat with friends in the White Mountains of New Hampshire. The stock market was down 5.3% the first few days after the open that day. 

Buying stocks quickly that day worked for me as I had put 10 good til cancel limit orders in before I left for vacation the day before because the market had already become jittery. All ten trades hit as over 765 stocks in the Russell 3000 were down more than 10%. I got stocks like Google (GOOG), Lockheed Martin (LMT) and Intel (INTC).
