Why it matters
It explains why different assets can suddenly move together.
Operational use: this is how the market taxes urgency. When it appears, slow down or size down.
Common trap
Assuming it’s a fixed label rather than a shifting regime.
Example
During risk-off, USD and safe havens strengthen while risk assets sell.
Operational cue: if you can’t point to it on the chart, in the DOM, or in your broker logs, treat it as a story and trade smaller.
Notes
Risk-on/off is a shorthand for liquidity and positioning shifts.
Quick rule
- If you see this repeatedly, you are in a different regime than your model assumes.
- Regime change usually means position size change.
- When in doubt: trade smaller, or don’t trade.
