IEX Increases Crumbling Quote Protection in Displayed Trading

IEX Exchange updated ‘The Signal’, its predictive model that targets adverse price changes in April this year and has now expanded Version 6 into displayed trading. The Signal, also known as the crumbling quote indicator, was introduced to predict which way the market will move in order to protect customers from trading at a price that will imminently become stale. In April the new version of The Signal was introduced for D-Peg, P-Peg, and C-Peg, IEX’s non-displayed Signal-enabled pegged order types. Since November 10, 2023 version six of The Signal has applied to all D-Limit orders as a default – both displayed and non-displayed.
