0DTE（当日到期期权）

中文解释

0DTE 指当天到期的期权合约。它们的 Gamma、Charm 和流动性状态会在盘中快速变化，因此对冲流会对价格移动和时间衰减非常敏感。Nightwatch 会把 0DTE 结构作为已启用 Dealer GEX 视图的独立盘中背景处理。

English definition

0DTE options are contracts that expire on the same trading day. Their gamma, charm, and liquidity profile can change very quickly, which makes intraday hedging flows more sensitive to spot movement and time decay. Nightwatch treats 0DTE structure as a distinct intraday context for enabled Dealer GEX views.

在 Nightwatch 里怎么看

Dealer GEX Chart 面向 0DTE 与日内交易，盘中实时刷新当天的关键价位；Replay Lab 可以从最近 90 天里挑一个交易日，用当天真实的结构与期权价格，把 SPX 0DTE 从开盘到收盘重走一遍。仅作市场结构参考，不构成买卖建议。

Dealer GEX Chart is built for 0DTE and intraday trading, refreshing the session's key levels in real time; Replay Lab replays SPX 0DTE sessions from the last 90 days, open to close, with that day's actual structure and option prices. It is market-structure context, not financial advice.
