CBOE to Launch 23x5 U.S. Equities Trading on EDGX in December

The Chicago Board Options Exchange (CBOE) announced plans to launch 23x5 U.S. equities trading on its EDGX Equities Exchange in December, which will enhance access to nearly round-the-clock trading. This development is expected to influence market dynamics through increased liquidity and expanded trading hours, potentially altering the rate differential for equities. Stocks and ETFs, particularly those with high trading volumes or volatility, are likely to be most affected as traders seek to capitalize on extended trading opportunities. Market participants will be closely watching the implementation details and any updates regarding eligibility requirements for extended-hours options, as these could impact trading strategies and market behavior.

HIGH-impact news is typically a market-moving event with multi-pip or multi-percent intraday reactions. Examples include central bank rate decisions, major CPI/NFP releases, geopolitical shocks, mega-cap earnings beats/misses, and regulatory announcements. Traders typically position-reduce or hedge ahead of scheduled HIGH-impact events, and follow the wire in real time to react to unscheduled ones (war headlines, central-bank emergency statements, surprise corporate actions). The Trading News Terminal squawk box reads every HIGH-impact headline aloud the moment it hits the wire — so active traders don't have to stare at the feed.

Active traders typically follow a three-step workflow when a market-moving headline hits the wire: (1) read the headline on the terminal or hear it on the squawk box; (2) assess whether the news is already priced in (by checking intraday price action in the seconds before) or whether it's genuinely new information; (3) act — either entering a breakout position, fading an overreaction, or tightening stops on existing trades. Trading News Terminal's Pro plan delivers wire-grade headlines within seconds of the source, with automatic audio squawk on every HIGH-impact event, so the read-assess-act cycle never waits on a refresh button.
