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
  

Notas de prensa:

Updated weighting and components of the indices.

Removed the smoothing option because it's redundant, everything that makes the indi load faster is good.

Notas de prensa:

FTX shut down so I replaced that data with Binance BUSD markets.

I also changed the weighting so that more actively traded markets have a bigger impact on the basis calculation.

Notas de prensa:

Big update under the hood.
I adjusted all the indices and calculations so that it more accurately reflects the official index premiums that the exchanges use.
I also added an option to look at individual exchange premiums, but by default it'll show the global average premium.

I also inverted the colours because it made more sense that positive values are green I thought.
