How I used NYSE TICK today w/ extremes ~ -1.000: In correction steep DT after news hit the wires 17:36 CET that US is weighing to limit US investors' portfolio flows into China, a move that would have repercussions for billions of dollars in investments pegged to the major indices; also they're apparently pondering delisting of Chinese companies from US stock exchanges (Bloomberg). DJI dives 200 pts in 3 mins; Alibaba plunges 6%, JD.com 5.3%, Baidu 3% (CNBC). Please check the M1 chart for how TICK dived to -1.000 at 17:36 CET, but corrected right next M1, while $SPX was still falling as perfect example for finding the right long entry point.
