What is Expected Move (DeepGamma)?
Option prices contain a forecast: the move the market expects out to a given expiration. Expected Move turns it into a band around price. It isn't a direction call, it's an order of magnitude — the distance the market currently considers normal, beyond which a move becomes statistically unusual.
What DeepCharts does better
Rendered natively next to your order flow, Expected Move becomes a management tool rather than a statistic you look up elsewhere. Inside DeepGamma it sits alongside total options volume and net option delta: expected range, the activity underpinning it, and the directional bias of the flow, on one screen and one dataset.
Using it day to day
Use it to calibrate, not to enter. If the day's expected range is narrow, your targets should be too and breakouts deserve suspicion. If it's wide — FOMC day, CPI day — your usual stops are too tight and the morning range probably won't hold.
Example: on a quiet Tuesday, Expected Move gives a narrow band. The market opens, tests the top of it and stalls; aiming twice as far would have turned a good read into a round trip. On CPI Thursday the same band doubles: the trader keeping yesterday's stop gets taken out on first-minute noise.
⚠ The trap to avoid
The trap: taking it as a hard ceiling. An expected-range band is a probability, not a wall — it gets exceeded regularly, and those are precisely the sessions where the biggest moves happen. It's a sizing tool, not a reversal level.
Combine it with
Combine it with Gamma Bands (the session's regime) and the GEX Profile (the levels that structure the range). Together they tell you what size of move to aim for and where it's likely to stop — order flow tells you when to enter.
FAQ
How is Expected Move calculated?+
It derives from the implied volatility of options at the chosen expiration: the options market prices a magnitude, which is converted into a price band around the current level.
Can I trade the Expected Move boundaries?+
They're mainly for sizing targets and stops. Treating them as reversal levels assumes the range won't be exceeded, which happens regularly — especially on data days.
Is it useful for scalping?+
Yes, indirectly: a narrow expected range signals a range session where targets should be short, a wide one signals impulsive moves where holding longer pays.
