Tilt is an emotional spiral — usually triggered by a loss, a missed move, or a run of red — in which you abandon your process and trade on raw emotion. It's the single fastest way to turn a bad day into a catastrophic one.

How the spiral starts

It begins with a loss that feels unfair. The urge to "win it back" takes over: you take a trade you'd normally skip, size it too big, skip the stop (revenge trading). That loses too, which intensifies the urgency — and now you're trading to soothe a feeling, not to follow an edge (loss aversion).

Why it's so dangerous

On tilt, every discipline that keeps you alive — sizing, stops, patience, sitting out — is exactly what emotion tells you to break (position sizing). A single tilt session can erase weeks of disciplined gains, because the losses come oversized and unplanned (risk of ruin).

Tilt doesn't feel like recklessness from the inside. It feels like urgency, like justice, like just one more trade to make it right. That's exactly why it's lethal.

Catching and stopping it

The fix is a pre-committed rule you set when calm: after N losses or a set dollar drawdown, you're done for the day — walk away, no debate (sitting out). A daily loss limit is a circuit breaker for your own psychology. A mechanical system has this built in: it can't tilt — it sizes and stops identically after a loss as before one, and never argues with the stop-for-the-day rule you set for yourself (emotional discipline).
