Today, we look even further back. 83 years back to be precise to this date in hallowed antiquity, when in 1929 the selling had officially begun, with what would ultimately culminate as the Great Crash. Cue Art Cashin: "on this Thursday morning, the market opened nervous but relatively steady. Within the first half hour, prices began to fade and the tape began to run late. By noon the tape was nearly an hour and-a-half late in reporting transactions in a market that had opened only two hours before. To speed the reporting digits were deleted and so "Radio" which had opened at 68 3/4 now showed on the tape at 8 3/4. But prices were moving so fast that the price was not 58 3/4 but 48 3/4 on its way to 48 1/4 before it would bottom in the afternoon at 44 1/2. To avoid confusion the Exchange published flash prices of selected securities on the slower moving bond tape."
