The signal in one sentence
Use SPY’s session range (high minus low) and the close’s position within that range to gauge how strongly buying or selling dominated by the end of the session.
Why this signal matters
Price can move a lot without revealing much conviction if it finishes near the middle of its range; conversely, a finish near the top or bottom of the range can imply more persistent demand or supply into the end of the session. This is measurable using only the high, low, and close: SPY high 756.68, low 751.76, close 754.83.
How to read it (simple checklist)
- Step 1: Compute the range. Range = 756.68 − 751.76 = 4.92.
- Step 2: Compute where the close sits inside the range. Close position = (754.83 − 751.76) ÷ 4.92 = 0.624 (about 62% up from the low).
- Step 3: Sanity-check the extremes. Distance from high = 756.68 − 754.83 = 1.85; distance from low = 754.83 − 751.76 = 3.07.
- Step 4: Interpret. A close closer to the high than the low can suggest firmer demand into the end of the session; closer to the low can suggest firmer supply; near the middle can suggest balance.
If/Then scenarios (exactly 3)
- If the close position is near 1.00 (very close to the high), then it often reflects stronger late-session buying pressure.
- If the close position is near 0.50 (mid-range), then it often reflects a more two-sided session where neither side clearly dominated by the end.
- If the close position is near 0.00 (very close to the low), then it often reflects stronger late-session selling pressure.
Common misreads
- Ignoring the size of the range: A close near the high means more when the range is meaningfully wide (4.92 here) than when the range is tiny.
- Overfitting a single session: One close position (about 62% here) is a snapshot, not a standalone verdict on longer-term direction.
- Confusing “up from the low” with “strong trend”: A close position above 0.50 can happen in both trending and choppy environments.
Bottom line (2 sentences)
SPY’s range is 4.92, and its close sits about 62% of the way up from the low, closer to the high than the low. This simple placement metric helps you quantify end-of-session pressure without needing any narrative.
