Bollinger Band CloudThis script shows a cloud of Bollinger bands of various period lengths surrounding price action.
The bands can be set to 1.25, 2.25 or 3.25 standard deviations.
Functionally, where bands start to converge, especially using 1.25sd, indicates fairly reliable support/resistance. If price action breaks through, price may start trending.
There is also an option to flag price action that breaks through 3.2sd for periods lengths greater than 14. When this happens, watch for a possible stall or reversal.
This concept is merely standing on the shoulders of @acatwithcharts and @dadshark, and I highly recommend using this alongside their indicators. Do yourself a big favor and get to know their work on Advanced Volatility Theory.
