How to read these numbers

This edition reads TradingFlow's Daily Market Recap for October 28, 2026, captured on October 30 (New York time). Two runs a minute apart printed the same figures. It is a completed-session report, not a trade recommendation.

Two clocks apply. Premium, sentiment, and prints describe the session tape; GEX and IV are the recap's T+1 / prior-close snapshots, not a live intraday gamma map. Neutral premium supplies no direction, and call share is option type, not bullish sentiment. Net DEI is an unsigned magnitude relative to typical activity; Net DEX is a separate signed classification, and a +0M reading rounds to zero. GEX is modeled chain structure under TradingFlow's dealer-sign convention, not observed dealer inventory, a support level, or the next session's direction. Ticket tags do not prove who bought or sold or whether a position opened, and intraday_pct is a first-to-last underlying-price proxy from the option tape, not a verified daily return.

Reproduce the findings

1. Open the October 28 recap; confirm Oct 28, 2026 in the session KPI.
2. Open the October 27 recap beside it and compare the KPI strip, leaders, and all six index GEX rows.
3. Compare the headline name's cards and largest tickets on both days: MU on October 28, TSLA on October 27.
4. Read Steps 4–6 separately: exposure magnitude, volatility rank, and index structure.

这个交易日证明了什么

如何阅读这些数字

本期读取 TradingFlow 2026 年 10 月 28 日 Daily Market Recap，于 10 月 30 日（纽约时间）采集。相隔约一分钟的两次运行数字一致。这是已完成交易日的报告，不是交易建议。

请分开两个时钟：权利金、情绪与成交记录描述当日成交；GEX 与 IV 是报告的 T+1 / 前收盘快照，不是实时盘中 gamma 地图。中性权利金不提供方向，call 占比是期权类型，不是看多情绪。Net DEI 是相对常态活跃度的无符号幅度；Net DEX 是独立的带符号分类，+0M 读数四舍五入为零。GEX 是 TradingFlow 做市商符号约定下的模型期权链结构，不是已观测的做市商库存、支撑位或下一交易日方向。成交标签不证明谁买谁卖或是否开仓；intraday_pct 是期权成交中标的价格从首笔到末笔的代理变化，不是核验过的日收益率。

复现这些读数

1. 打开 10 月 28 日报告，确认交易日 KPI 为 Oct 28, 2026。
2. 同时打开 10 月 27 日报告，对照 KPI、活跃榜与全部六行指数 GEX。
3. 对照两天焦点标的的卡片与最大成交：10 月 28 日为 MU，10 月 27 日为 TSLA。
4. 分开阅读步骤 4–6：敞口幅度、波动率排名与指数结构。
