Macro regimes — VIX, DXY, TNX, oil.

You don't wear shorts in winter and you don't wear a parka in summer. Same idea applies to trading: different macro regimes call for different operational modes. The framework reads four numbers — VIX (volatility), DXY (dollar), TNX (10-year yield), oil — and uses them to classify the day's regime. The same chart-reading discipline that wins in a low-vol grind regime loses in a stressed risk-off regime; the same setup that fires beautifully under disinflation breaks down when yields are spiking. The framework's regime engine doesn't predict; it classifies. Your job is to know which clothes to wear based on the classification.

The four numbers

• VIX (volatility) — implied volatility on the S&P 500. Below 15 = complacent; 15-22 = normal; 22-30 = stressed; 30+ = panic. Most retail strategies built between VIX 12-22 break above 30.
• DXY (dollar) — the dollar index versus a basket of major currencies. Rising DXY = global liquidity tightening (risk-off for equities historically). Falling DXY = liquidity easing (risk-on).
• TNX (10-year yield) — the 10-year Treasury yield. Sharp rises = duration repricing, growth-stock pressure. Sharp falls = recession-fear bid for safety. Stable = neutral.
• Oil (WTI / Brent) — energy prices. High oil = inflation pressure + consumer drag. Falling oil = deflation pressure + consumer relief. Energy sector responds inversely to most others.

The five regimes the framework classifies

• Risk-on grind. VIX < 18 · DXY flat-to-down · TNX stable · oil mid-range. The "easy" regime. Trend strategies dominate. Sector rotation is gentle. Most setups fire and follow through.
• Late-cycle euphoria. VIX 12-15 (very complacent) · TNX rising · oil rising. Looks like risk-on but isn't — every component is stretched. Trend continuation works until it doesn't, and the "doesn't" is sudden. The framework's pillar gates get stricter here; the watchlist's Grade-A hurdle effectively rises.
• Defensive regime. VIX 18-25 · DXY rising · TNX rising. Equity-unfriendly tape; defensive sectors outperform. Anchors sleeve (Lesson 13) earns its keep. Sports Cars sleeve gets trimmed; Emerging gets refused entirely.
• Stressed risk-off. VIX 25-35 · DXY rising · TNX falling (flight to quality). Panic territory. Sector correlations spike to 1; everything moves together. The 7% drawdown gate becomes the operative gate, not the per-trade R:R floor.
• Capitulation / inflection. VIX 35+ · oil/DXY/TNX moving violently in any direction. Most setups don't fire. The framework refuses most entries. The right read is "wait" — the regime hasn't settled.

What changes by regime

The framework adjusts several gates based on regime classification. The trader doesn't need to memorize the adjustments — the dashboard surfaces them — but understanding the logic helps:

• Risk-on grind: Trend strategies prioritized. Sector cap can run to 30%. Sports Cars sleeve up to 50%. R:R floor stays at 2:1.
• Late-cycle euphoria: R:R floor effectively raised to 2.5:1 via Grade-A hurdle increase. Mean-reversion mode partially licensed alongside trend. Trim discipline tighter on extended winners.
• Defensive: Anchors sleeve target rises to 25-30%. Sports Cars sleeve trims to 25-35%. New entries restricted to defensives + Grade A only.
• Stressed: 7% drawdown gate tightens to 5%. New entries refused except hedges. Existing positions get conservative trims if they cross the catalyst window.
• Capitulation: Effectively trade-halt mode. Manage existing only. Wait for regime to settle before any new entry.

Why "predict the regime" is the wrong frame

Every retail-strategy newsletter you'll ever read tries to predict the next regime shift. "Recession is coming." "The Fed will pivot." "The dollar is rolling over." The framework explicitly doesn't predict. It classifies what's happening now based on the four readable numbers and adjusts gates accordingly. When the regime shifts, the classification shifts; the gates shift. There's no anticipation step that has to be right.

This is the same reason Lesson 3 framed trading as referee work, not commentary. The commentator predicts; the referee enforces. The regime engine is a referee. Yesterday's regime classification doesn't bind today's; today's setups are sized for today's reading.

Trend mode vs mean-reversion mode

The framework's two operational modes correspond loosely to regime:

• Trend mode — risk-on grind + (sometimes) late-cycle euphoria. Setups: confluence breakouts, pullback continuations, chandelier-trail-the-winner. R:R floor 2:1. Frame: "trade what's working."
• Mean-reversion mode — defensive + part of stressed. Setups: oversold bounces at major confluence, range fades, defined-risk reversal trades. R:R floor 1.5:1 (looser because shorter holding periods). Frame: "trade the reversion to mean."

Most retail blow-ups happen when the trader runs trend strategies in a defensive regime or mean-reversion strategies in a strong trend. The framework's regime classification is what steers the trader into the right mode without requiring the prediction.

What the framework does

• Regime engine reads VIX/DXY/TNX/oil every audit cycle, classifies into one of the five buckets
• Regime chip on the global header surfaces the active regime in plain English
• Mode flag propagates into the candidate scanner — sets the R:R floor, the sleeve targets, the sector cap defaults
• Diplomatic decay indicator adjusts the regime classification when geopolitical risk rises (Lesson 21's territory — feeds the Sovereignty Cap)

The real lesson

Different regime, different trades. The disciplined trader doesn't fight the regime — they read it and adjust the operational mode. The four numbers (VIX, DXY, TNX, oil) are enough to classify reliably. The regime engine does the classification; the mode flag adjusts the gates. The trader's job is to trust the read — including when "wait" is the recommended action and the urge to find something to trade is loudest.
