Volatility clusters: quiet begets quiet, and then the tape expands — a VIX spike, a shift into negative gamma, a catalyst. Ranges widen, moves extend, and the reversion tactics that print on calm days become traps. Trading an expanding tape is a different game with different rules.
What changes
Momentum over reversion. In an expanding, negative-gamma tape, hedging amplifies moves — so you trade continuation (ignitions, pullback entries), not fades. Size down. Wider ranges mean a stop that's the “same” in structure is a bigger dollar move — cut size so the larger swings stay survivable. Wider stops or none. Tight mean-reversion stops get run by ordinary expansion noise; give trades room or stand aside.
The counterintuitive sizing
Beginners size up when volatility rises — “bigger moves, bigger profits.” That's backwards. Bigger moves also mean bigger losses and faster reversals, so the correct response to expansion is smaller position size, letting the wider range do the work on fewer contracts. Survival first; the expanded range provides plenty of profit on modest size.
When the tape opens up, the market rewards momentum and small size. Trading bigger into higher volatility is how expansion days end accounts.
How to trade it
Confirm the regime is genuinely negative-gamma / expanding (via the filter and rising range), respect trend, take momentum entries at levels, and keep size small. Bank winners — expansion moves can reverse as fast as they run. And know that expansion often follows a compression, so a quiet coil is a heads-up. NoVo's regime read flags the shift, and its conviction sizing pulls size back exactly when the tape gets dangerous rather than pushing it.
