What is the beginner read after a lower-band rejection?
Treat it as a possible mean-reversion bounce toward the middle band if price reclaims and RSI is no longer falling apart.

Lower Band Mean Reversion
A Lower Band tag with a rejection wick can mean-revert toward the Middle Band. Confirm with a reclaim and rising RSI.
The lower band is the bottom of the volatility envelope, about two standard deviations under the 20-day average. A tag down there can be a mean-reversion setup when the candle rejects — a wick through the band and a close back inside — and RSI is washed out but not required to print a fantasy reading like 10.
The higher-probability beginner frame is a possible bounce toward the middle band if price reclaims, not a claim that the company is going to zero and not a rule that the signal is invalid unless RSI is extreme.
Confirm the reclaim. A lower-band tag that keeps closing lower is a trend, not a bounce. The drill asks you to tell those apart before the 8-day path is revealed.
How To Read It
- Mark the lower band and the rejection wick.
- Check whether RSI is soft, often in the 30s, without demanding a perfect number.
- Look for price to reclaim back inside the band before you call it a bounce.
Common Mistake
Shorting every lower-band tag as if the stock must go to zero, or discarding the signal because RSI is not under 10.

Key Takeaways
- Location plus rejection matters more than the tag alone.
- The middle band is the typical mean-reversion magnet, not a guaranteed target.
- Daily bands are a valid study frame. You do not have to wait for a weekly chart.
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
Does the lower band mean the downtrend is over?
Not by itself. It marks a stretched location. The bounce case needs a reclaim. Continued closes under the band argue the trend is still in charge.
How low must RSI be?
There is no magic print such as 10. A soft RSI in the 30s alongside a rejection wick is enough to study the setup.

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).
