Keltner Ch Strategy from TradingView

Tradingview.com has a indicator that they refer to as the Kelter ch strategy. Under the right conditions it seems to have some value.

I would like to get these indicator inserted into Tradovate. I know nothing of JavaScript. The link below is to a image of the Tradingview chart with the indicator. This is an indicator that uses the Keltner channel. It is not the Keltner channel which is already in Tradovate.
