Let me share the profit curve of BTCDOM and ETH combination. This is a pinescript: https://pastebin.com/3bn0vfVd

Written by AI. The blue line is the curve of the combination, the red line is BTCDOM, and the orange line is the moving average of the combination curve.

I only know a little bit of js and don't really understand those things in tradingview. Here I'm throwing out an idea; those who are interested can use this as a reference to improve a strategy.

The combination is: BTCDOM : ETH = 2 : 1.
