Where I think it helps a little:
- On risk-off mornings, when equities gap down and gold is bid, I'm much more careful with fading USD strength. The smile says that kind of bid can persist.
- After strong US data, the same logic says long-dollar moves can extend. I'm slower to short USDJPY into it.
- Entry timing. The smile says nothing about the next 15 minutes.
- Choosing between pairs. EURUSD and AUDUSD can react very differently to the same risk mood.
- Quiet days. Most days are nowhere on the smile, just noise.
Does anyone actually trade intraday off macro frameworks like this, or do you also keep them in the background?
