Dumb finance question thread of the day - I'm going to try & explain how IEX's D-Limit order works below. For those who know more than me, please tell me if I'm close to right or completely off-base. Thanks in advance:

In comes IEX's D-Limit order type. IEX sees the market for TSLA moving up & trips its "crumbling quote" signal, which automatically re-prices its 10 shares from $1,005 to $1,006 so HFT firm can't profit from them. Big Buyer completes its order & still pays $1,006.pic.twitter.com/gqJMIXV97q

Upside of D-Limit Order: - prevents HFT firm from profiting off latency arbitrage Downside of D-Limit Order: - doesn't really lower costs for Big Buyer which is goal in the first place
