Ethereum Perpetual Swaps Basis

This is a simplified version of my Aggregated Perpetual Swaps Basis script.
Click the image to see more details on that indicator.

This version works only for ethereum (the older script works for BTC and ETH) and a bunch of code has been trimmed down.
The purpose of this is to make the indicator a lot faster.

When I published the old one I noticed that it always took a long time to load which is incredibly frustrating to me.
I guess I propped too much stuff in one indicator.
So that's why I'm basically cutting it up into two, more code efficient pieces, but it does the same thing.
People who have access to the old indicator will also get access to this one.

Here's a list of contracts that I used to make the perps and spot indices.
These will be updated if needed (in case an exchange loses relevancy for example).

Perps:

• Binance USDT margin
  
• Binance coin margin
  
• Bybit USDT margin
  
• Bybit coin margin
  
• FTX perp
  

Spot:

• Coinbase USD
  
• Bitfinex USD
  
• FTX USD
  
• Binance USDT
