Bollinger BandWidth
VolatilityOwn panel belowThe width of the Bollinger band pulled out as its own line.
What it looks like
Drawn by running the real calculation over one sample series. Open a symbol and it is recalculated on that symbol's bars.
How to read it
A reading near its floor means the band has squeezed very tight — a quiet stretch. Large moves often follow, which is why it is used to find squeezes.
Where it misleads
A squeeze says nothing about which way the move will go.

One tap to add
Open a symbol, tap the name in the indicator list and it is drawn straight away. You can stack several copies of the same indicator with different settings.
Recalculated per timeframe
Switch between minute, hourly, daily, weekly or monthly bars and it is recalculated on that timeframe. The maths runs over every bar loaded, so zooming never moves the line.
Use it as a search condition
Some indicators can also be used as an axis when searching for symbols — for example, keeping only symbols above a given reading, scanned every night.

Every indicator is an observation computed from past bars. It does not tell you future prices and it is not investment advice.
