0DTE allows users to take very short-term positions and hedges on the market. The outcome of the trade is known the same day, and less capital is needed than equivalent strikes with further dated expiries. 0TE options tend to be highly liquid with higher trading volumes and very tight bid-ask spreads. With potential lower premiums, they can be less expensive to trade short-term volatility. But short-term options, particularly 0DTE options, can come with risks due to potential intraday volatility and limited time to expiration. -Cboe
