The signal in one sentence
The signal is SPY’s intraday range (high minus low) and where the price finished inside that range, using SPY high 748.94, low 744.48, open 746.24, and close 745.64.
Why this signal matters
A wider daily range can reflect higher disagreement about price, while a narrower range can reflect tighter agreement; neither is “good” or “bad” on its own. Separately, a finish near the upper or lower end of the range can hint at whether buying or selling pressure was more persistent across the session.
How to read it (simple checklist)
- Step 1: Measure the range. Range = 748.94 − 744.48 = 4.46.
- Step 2: Compare finish vs. open. Close − Open = 745.64 − 746.24 = −0.60.
- Step 3: Locate the close within the range. Close position = (745.64 − 744.48) / (748.94 − 744.48) = 1.16 / 4.46 ≈ 0.26 (about 26% up from the low).
- Step 4: Note whether the finish is closer to the low or high. Distance to low = 745.64 − 744.48 = 1.16; distance to high = 748.94 − 745.64 = 3.30.
If/Then scenarios (exactly 3)
- If the range is relatively large and the close sits near the lower portion of that range (here ≈ 0.26), then price moved a lot but finished with more selling pressure into the end of the session.
- If the range is relatively large and the close sits near the upper portion of the range, then volatility was high but buyers kept control later in the session. Data not provided for that alternative finish.
- If the range is relatively small and the close is near the middle of the range, then the session can be read as more balanced, with neither side sustaining a strong advantage. Data not provided for a “small range” benchmark.
Common misreads
- Confusing range with direction: A range of 4.46 says nothing by itself about whether the day “should” be bullish or bearish; direction comes from where the close sits and how it relates to the open.
- Ignoring the open: The close of 745.64 being 0.60 below the open of 746.24 adds context that a simple “up from the low” reading can miss.
- Overweighting one session: One day’s close position (≈ 26%) can be noisy without a larger sample. Data not provided for a multi-session comparison.
Bottom line (2 sentences)
Using SPY’s high 748.94 and low 744.48, the intraday range is 4.46, and the close 745.64 sits about 26% up from the low. Combined with a close that is 0.60 below the open, this configuration reflects movement with a finish that leaned more toward the lower end of the day’s path.
