Bollinger Squeeze
When bands pinch tight around the 20-Day Middle Line, a Squeeze often precedes expansion. Trade the break, not the coil.
A Bollinger Squeeze is a multi-week pinch. The upper and lower bands pull tight around the 20-day middle line because realized volatility has dried up. Quiet bands are not a forecast of more quiet. They are a coil that often resolves with an expansion.
The useful read is patience. Price pressing the middle band during a squeeze is not a short signal, and an old upper-band tag is not a reason to fade the next break. Wait for a decisive expansion and then follow the direction of that break.
On the chart, compare band width now with the width a few weeks earlier. If the envelope is the tightest it has been and price is coiling near the middle, you are looking at the squeeze, not at a completed trend.
How To Read It
- Find the narrowest band width in the visible window.
- See whether price is leaning on the middle line rather than already walking an outer band.
- Plan to judge the break only after the bands start to open.
Common Mistake
Treating a quiet squeeze as a promise of sideways chop, or fading the middle-band press before the expansion chooses a side.
The Question You Practice
The bands have pinched to a multi-week low width. Price just pressed the Middle Band. What is the most useful next read?
Key Takeaways
- Trade the break, not the coil.
- Band width, not a single candle color, defines the squeeze.
- The middle band is the 20-day average, not a sell trigger.
Student Note — Why 8 Trading Days?
8 trading days (about 1.5 calendar weeks) is a uniform study window used across every drill and example so you can compare outcomes apples-to-apples — not a fixed market rule. Daily Bollinger Band, 14-Day RSI, and Moving Average swing setups normally play out over roughly 5 to 15 trading days rather than in a single day, whereas 30+ days often turns into a new macro or earnings story.
Questions
Should I ignore the chart because the bands are quiet?
No. Quiet bands are the condition that often comes before a range expansion. Ignoring breakouts is the miss.
Does a touch of the middle band mean I should short?
No. During a squeeze the middle band is just the average inside the coil. Direction is not decided until price expands.

Data Notes
Every candle is real Yahoo Finance daily history across a 36-setup verified pool (9 lesson types × 4 real-world US stocks). Bollinger Bands use a 20-Day SMA ± 2 population standard deviations. RSI Value uses a 14-Day Lookback (Wilder RSI). Moving Averages use the 20-Day and 50-Day Simple Moving Averages (each setup includes ≥60 warmup bars so the 50-Day SMA is real from bar 0). Each reveal measures the next 8 trading days (~1.5 weeks) as a consistent swing-study window (daily indicator setups typically play out over 5–15 trading days rather than 1 day, though there is no fixed rule).
