This edition reads TradingFlow’s Daily Market Recap for October 12, 2026, captured on October 13. The quoted figures agreed across two runs. This is a completed-session report, not a trade recommendation.

Keep two clocks separate: premium, sentiment, and prints describe the session tape; GEX and IV are the recap’s T+1 / prior-close snapshots. This historical recap is not a live intraday gamma map.

$14.2B, 64% calls, 22% bullish versus 24% bearish. MU led at $1.5B Mixed; SPX net GEX printed +61.43B, Positive.

What the recap printed

October 12 session KPI strip

Test app, session 2026-10-12, KPI. Captured October 13, 2026.

Reading	Recap value
Single-name premium	$14.2B
Call / Put	64% / 36%
Bullish / Bearish	22% / 24%
Overall tone	leaned bearish
First 30-minute window	09:30 · $2.4B

Sentiment bars: Neutral $7.8B, Bullish $3.1B, Bearish $3.4B. Call share is option type, not bullish sentiment. Neutral premium supplies no direction; rounded buckets need not sum exactly to the rounded KPI total.

October 12 premium by sentiment

Test app, session 2026-10-12, Step 1. Captured October 13, 2026.

Leaders: where premium concentrated

October 12 top names by premium

Test app, session 2026-10-12, Step 2. Captured October 13, 2026.

Symbol	Premium	Call	Put	Net bias
MU	$1.5B	$900M	$642M	Mixed
META	$1.2B	$887M	$304M	Bullish
SNDK	$870M	$410M	$459M	Bearish
NVDA	$857M	$559M	$298M	Bearish
AMD	$635M	$431M	$203M	Bearish
TSLA	$555M	$348M	$207M	Bearish

MU was Mixed and META was Bullish, while SNDK, NVDA, AMD, and TSLA were Bearish. The two biggest premium names did not mirror the market-wide bearish lean.

The bottom line and glance show MU $1.5B; the leaders table and headline cards show MU $1.5B. Preserve these field readings rather than reconciling them into a new number.

October 12 bottom line and glance

Test app, session 2026-10-12, Bottom line / glance. Captured October 13, 2026.

Exposure and volatility context

The glance lists INTC +0M shares-equiv. as largest Net DEX and META 189% as largest Net DEI magnitude. Step 4 prints META 189%, with Negative Net DEX. DEI is an unsigned activity-relative magnitude; DEX provides a separate signed classification. Neither proves opening intent or actual dealer inventory.

The +0M shares-equiv. DEX reading is rounded to zero. It does not support a directional inference. META’s Bullish flow tag also differs from its Negative DEX classification; they measure different things.

Step 5’s highest IV rank among active names is AMZN 55 / 100, with 39.9% 30-day implied volatility. This is snapshot volatility context, not realized session volatility.

Index GEX: SPX Positive

October 12 index GEX backdrop

Test app, session 2026-10-12, Step 6 · T+1. Captured October 13, 2026.

Index	Net GEX ($B)	Regime
SPX	+61.43	Positive
QQQ	−3.93	Negative
SPY	+3.48	Positive
IWM	−1.98	Negative
NDX	−0.93	Negative
DIA	+0.12	Positive

SPX, SPY, and DIA were Positive; QQQ, IWM, and NDX were Negative. Positive SPX structure therefore coexisted with negative technology-index readings.

GEX describes modeled chain structure under TradingFlow’s dealer-sign convention. The regime does not establish observed dealer inventory, a support level, a pin target, or the next session’s direction.

Headline name: MU at $989

MU headline cards for October 12

Test app, session 2026-10-12, Step 8. Captured October 13, 2026.

Cards: last $989, premium $1.5B, 58% calls, 19% bullish, 63% average IV on traded contracts. The headline name is selected by premium, not by the largest price move.

Time	Type	Strike	Expiry	Premium	Sentiment
15:33	PUT	1,000	2027-01-15	$8M	BULLISH
15:32	CALL	780	2026-10-16	$4M	NEUTRAL
15:37	CALL	780	2026-10-16	$4M	NEUTRAL
10:18	PUT	980	2027-12-17	$4M	NEUTRAL
10:18	CALL	1,150	2027-12-17	$4M	NEUTRAL
15:19	CALL	850	2026-12-18	$3M	NEUTRAL

MU biggest prints for October 12

Test app, session 2026-10-12, Step 8 · prints. Captured October 13, 2026.

The largest listed ticket was 15:33 1,000 PUT, expiry 2027-01-15, premium $8M, tagged BULLISH. The largest displayed ticket was a put tagged Bullish. The option type alone does not tell us its directional classification.

Ticket tags do not prove who bought or sold, whether a position opened, or whether adjacent prints form a single strategy.

Movers: BMBL +49.6%

October 12 intraday movers

Test app, session 2026-10-12, Step 7. Captured October 13, 2026.

Bottom line: BMBL +49.6%. Step 7 in both runs: BMBL 49.6%, Up. Keep both displayed fields. The bottom line names the largest gain; Step 7’s key can select a gain or loss across runs.

The intraday_pct reading is a first-to-last underlying-price proxy in the option tape. It is not an independently verified daily stock return, and movers do not prove flow causality.

What this session is evidence of

Question	TradingFlow reading	Clock
Size / tone	$14.2B · 22% Bullish / 24% Bearish	Session tape
Concentration	MU $1.5B Mixed	Session leaders
Relative exposure	META DEI 189% · DEX Negative	Session exposure
Volatility	AMZN IV rank 55 · IV 39.9%	T+1
Index structure	SPX +61.43B Positive	T+1
Largest print	MU 1,000 PUT 2027-01-15 $8M BULLISH	Session ticket

复盘显示了什么

10 月 12 日交易日 KPI

测试应用，交易日 2026-10-12，KPI。采集于 2026 年 10 月 13 日。

读数	复盘数值
个股权利金	$14.2B
Call / Put	64% / 36%
Bullish / Bearish	22% / 24%
整体情绪	leaned bearish
首个 30 分钟窗口	09:30 · $2.4B

情绪柱：Neutral $7.8B、Bullish $3.1B、Bearish $3.4B。Call 占比是期权类型，不是看多情绪。中性权利金不提供方向，取整后的桶值之和也未必恰好等于取整后的 KPI 总额。

10 月 12 日各情绪权利金

测试应用，交易日 2026-10-12，Step 1。采集于 2026 年 10 月 13 日。

活跃榜：权利金集中在哪

10 月 12 日权利金活跃榜

测试应用，交易日 2026-10-12，Step 2。采集于 2026 年 10 月 13 日。

标的	权利金	Call	Put	净情绪
MU	$1.5B	$900M	$642M	Mixed
META	$1.2B	$887M	$304M	Bullish
SNDK	$870M	$410M	$459M	Bearish
NVDA	$857M	$559M	$298M	Bearish
AMD	$635M	$431M	$203M	Bearish
TSLA	$555M	$348M	$207M	Bearish

MU 标记为 Mixed，META 为 Bullish，SNDK、NVDA、AMD 与 TSLA 为 Bearish。权利金最大的两个标的，并未复刻全市场偏空的情绪。

Bottom line 与速览显示 MU $1.5B，活跃榜与焦点卡片显示 MU $1.5B。保留这些字段的读数，不另造一个合并数字。

10 月 12 日总结与速览

测试应用，交易日 2026-10-12，Bottom line / glance。采集于 2026 年 10 月 13 日。

敞口与波动率背景

速览的最大 Net DEX 为 INTC +0M shares-equiv.，最大 Net DEI 幅度为 META 189%。步骤 4 显示 META 189%，对应 Net DEX 为 Negative。DEI 是相对于活跃度的无符号幅度，DEX 提供独立的带符号分类。两者都不证明开仓意图或实际做市商库存。

+0M shares-equiv. 的 DEX 读数取整为零，不能据此推断方向。META 的 Bullish 资金流标签也与 Negative DEX 分类不同，两者衡量不同维度。

步骤 5 的活跃标的最高 IV rank 是 AMZN 55 / 100，30 天隐含波动率为 39.9%。这是快照波动率背景，不是当日已实现波动率。

指数 GEX：SPX Positive

10 月 12 日指数 GEX 背景

测试应用，交易日 2026-10-12，Step 6 · T+1。采集于 2026 年 10 月 13 日。

指数	净 GEX（$B）	环境
SPX	+61.43	Positive
QQQ	−3.93	Negative
SPY	+3.48	Positive
IWM	−1.98	Negative
NDX	−0.93	Negative
DIA	+0.12	Positive

SPX、SPY 与 DIA 为 Positive，QQQ、IWM 与 NDX 为 Negative。因此 SPX 正结构与科技指数负读数同时存在。

GEX 描述 TradingFlow 做市商符号约定下的模型期权链结构。环境标签不证明已观测库存、支撑位、钉住目标或下一交易日方向。

焦点标的：MU 显示 $989

MU 10 月 12 日焦点卡片

测试应用，交易日 2026-10-12，Step 8。采集于 2026 年 10 月 13 日。

卡片显示：最新价 $989、权利金 $1.5B、58% calls、19% bullish、成交合约平均 IV 63%。焦点标的按权利金选取，不是按最大价格涨跌选取。

时间	类型	行权价	到期日	权利金	情绪
15:33	PUT	1,000	2027-01-15	$8M	BULLISH
15:32	CALL	780	2026-10-16	$4M	NEUTRAL
15:37	CALL	780	2026-10-16	$4M	NEUTRAL
10:18	PUT	980	2027-12-17	$4M	NEUTRAL
10:18	CALL	1,150	2027-12-17	$4M	NEUTRAL
15:19	CALL	850	2026-12-18	$3M	NEUTRAL

MU 10 月 12 日最大成交

测试应用，交易日 2026-10-12，Step 8 · prints。采集于 2026 年 10 月 13 日。

最大一笔显示成交为 15:33 1,000 PUT，到期日 2027-01-15，权利金 $8M，标签 BULLISH。最大一笔显示成交是 put，却被标记为 Bullish。仅凭期权类型无法判断它的方向分类。

成交标签不证明谁买谁卖、是否开仓，也不证明相邻成交属于同一策略。

涨跌榜：BMBL +49.6%

10 月 12 日盘中涨跌榜

测试应用，交易日 2026-10-12，Step 7。采集于 2026 年 10 月 13 日。

Bottom line：BMBL +49.6%。两次运行的步骤 7：BMBL 49.6%，Up。保留两个显示字段。Bottom line 指向最大涨幅，步骤 7 的关键字段在不同运行中可能选择上涨或下跌标的。

intraday_pct 是期权成交中标的价格从首笔到末笔的代理变化，不是独立核验的股票日收益率。涨跌不证明资金流因果关系。

这个交易日证明了什么

问题	TradingFlow 读数	时钟
规模 / 情绪	$14.2B · 22% Bullish / 24% Bearish	当日成交

复现这些读数

打开 10 月 12 日报告，确认交易日 KPI 为 Oct 12, 2026。
先记录 KPI 与步骤 1 情绪，再读取活跃榜。
对照 MU 活跃榜标签、焦点卡片与最大成交。
分开阅读步骤 4–6：敞口幅度、波动率排名，以及全部六行指数 GEX。
保留两个涨跌字段、交易日与快照时钟。不要把报告转换成买卖指令。
