Topic: Keltner Channels
Learning FSB indicator development, please bear with me. These are written to be V2 compatible which means they'll work in the latest Beta of FSB & I presume the Pro version (which I haven't tried yet).
Firstly Keltner v2 is the same as the builtin Keltner, except it takes larger period values for the MA and the ATR, plus the ATR multiplier is a floating point number to 1 decimal place.
Keltner Channel Crossover was a bit more ambitious. It includes the above, but measures whether the high or low lines of a "fast" channel have crossed those of a "slow" channel, or if they're currently above or below the slow channel. The same could be applied to other MA based price channels, eg Bollingers, Starc Bands etc.
I hope they're helpful, and if you see anything wrong please let me know. The chances of something being wrong, especially with the Crossover, are probably pretty high
