Episode notes
Market-On-Close Moves Have Faded
- Market-on-close (MOC) end-of-day bursts used to be a predictable powder keg but have faded in recent months.
- Andrew Mack notes current MOC moves are rarer and often tied to month-end or new highs rather than daily mechanical rebalancing.
Train By Watching One Contract
- Watch a single contract's bid-ask spread and note when it jumps beyond its usual range to spot actionable anomalies.
- Record context (day, catalysts) and investigate repeatability before sizing trades.
Brainstorm Then Stress-Test Ideas
- Andrew emphasizes starting with creative brainstorming about patterns, then applying critical stress tests.
- He alternates creative and analytical modes to form and then refute hypotheses.
