I used to look at the expected move before a Fed print and treat it like a prediction. "Market says SPY moves $10, so I'll aim for 510." That mindset quietly cost me money for a while, and here's the fix.

The expected move is just a price. Take the option expiring right after the event, find the at-the-money strike, add the call and the put. If SPY is at 500 and the straddle costs $10, the market is pricing a move of about $10 either direction. That's not a forecast of where price lands. It's the cost of a bet that pays either way -- set by the market maker on the other side so that, on average, they break even.

One more thing that reframed it for me: that $10 maps to roughly one standard deviation. So price stays inside it about 68% of the time and blows through it about one event in three. It's a boundary, not a bullseye.

Which changes the whole question. You're not asking "up or down?" You're asking "is $10 too cheap or too expensive for what's coming?" Your edge isn't being right on direction. It's disagreeing with the price.

What a disciplined trader does: before every event, write down two numbers -- the implied move (the straddle) and the realized move from the last several times this event happened. If the last six CPI prints moved SPY ~$6 and this month prices $11, that gap is information. And whatever you conclude, size for the tail, not the average. The three-sigma day is coming; make sure it's survivable.

This is educational commentary, not personalized financial advice -- just the mental model I check now.
