How to read these MSFT call signals
Each MSFT call signal is a timestamped algorithmic detection of unusual MSFT options activity. Read the call or put direction together with its strike, expiration, detection time, and subsequent movement in the underlying. The archive preserves those observations for research; it does not tell visitors whether or when to trade.
For educational purposes only. Signals are observations of market activity — not financial advice or a recommendation to buy or sell any security. Options trading involves substantial risk, including the loss of principal. Do your own research.

How these MSFT signals are generated
- What a signal is
- A timestamped observation, not an instruction. A quantitative model watches MSFT options activity in real time and records a signal when volume and flow change in a statistically significant way. An AI layer then summarizes and contextualizes the detection; it does not generate it.
- Data sources
- Live MSFT options volume and flow, evaluated against one-minute open/high/low/close bars for the underlying. Those same bars are what every historical figure on this page is measured from.
- Timestamps
- Signal times are US Eastern (America/New_York) — the market's own clock — and are not converted to the visitor's local time zone. Underlying bars run from the 9:30 AM ET open to the 4:00 PM ET close.
- Update cadence
- Signals are published as they are detected, during the live window of 9:30 AM to 3:00 PM ET, Monday through Friday, excluding exchange holidays. This archive picks up new detections within about a minute; the aggregate statistics recompute daily.
- How outcomes are measured
- Entry is the one-minute bar at detection; exit is the bar at the observation's recorded close. Every figure is therefore intraday and same-session, never held overnight. All of it tracks the underlying's price movement, not option premiums and not profit and loss — actual option returns depend on quotes, fills, spread, and fees that this archive does not model.
- Known limits
- Signals with no matching intraday bar data are omitted from the statistics, and implausible moves are discarded as bad-data candles. Statistically significant activity describes what happened in the order book; it is not evidence that whoever traded it was informed or correct.

Questions About MSFT Call Signals
Astronomer has detected 18 MSFT call signals since February 2026.
Across 18 completed MSFT call signals since February 2026, the underlying moved in the signal's direction 88.9% of the time. Horizon is intraday and never overnight: entry is the one-minute bar at detection and exit is the bar at the observation's recorded close, both in the same trading session. The denominator counts only signals with both an entry and a close in that session — signals still open, signals with no intraday price data, and implausible bad-data candles are excluded. This measures the underlying's direction only. It is not option profit and loss, and it does not account for premium paid, bid-ask spread, slippage, or fees. Past performance does not guarantee future results.
Across 18 MSFT call signals with intraday price data, the underlying moved an average of 0.21% in the signal's direction at its intraday peak. Peak means the most favorable point reached during the session, not the price at any exit — capturing it would require selling at the exact high. The single best observation in the archive is a modeled 67.8% from a call on March 4, 2026 — that is the maximum, not a typical result, and it is derived from the underlying's move using a fixed 110x leverage assumption rather than any option price that was actually quoted or filled. These figures are not measured option profit and loss. Actual option returns require option quotes or fills. Past performance does not guarantee future results.
