This simple script provides Bollinger Band and Keltner Channel indicators, and will highlight areas where the Bollinger Bands enter into the Keltner Channel.
This script is based on the Failed Volatility Breakout (FVBO) System used by professional trader ChrisD_Macro. The default plot styles for the indicators in this script are based on Chris's setup, but visual styles as well as BB and Kelt settings (length, standard deviation, etc...) can all be easily customized with the user interface in the indicator settings.
You can also choose whether you want the condition to be triggered by just one Bollinger Band entering the Keltner Channel, or if it has to be both bands entering the channel.
This script is very useful when manually back testing the FVBO strategy, as it clearly highlights the BB-Kelt squeezes instead of having to constantly scroll in and out looking for them.
It can also be useful live as it has the ability to trigger TradingView alerts using the condition "BB-Kelt Squeeze".
Hope it's helpful - JDC
Side Notes:
With Forex / Currencies this indicator I usually use this indicator on the 1 Day time frame.
Keep in mind that the script includes the Bollinger Bands and Keltner Channels, so if you already have your own version of these indicators on your chart, it will get really messy. (Just hide the other indicators while you get to know this one).
