Hi,

I found a great custom indicator on TradingView, developed by Chris Moody. Here is a picture of the indicator on Bitstamp ETH/USD : 

https://www.tradingview.com/x/z8pYLlHG/

 

I think the color change makes a great trade signal (buy when it switches from red to green and sell when it switches from green to red).

I have the source code, which is in TradingView's language, now the big question is : is there an efficient way to implement this strategy without re-coding the whole custom indicator using Quantconnect's API ?

I know Python but I don't know TradingView's language. Any help is greatly welcome !

 

Here is the code of the indicator on TradingView :
