Bitcoin Spot Premium

Plots the difference between the Bitcoin Spot price and the average of 7 Futures prices.
The idea being that Spot leads the market, and when Spot is priced significantly higher than Futures, price should increase. And vice-versa.

Possible uses:

• Sharp changes could indicate a reversal is coming
  
• A consistently large premium can be used as additional validation of trend continuation
  
• Divergences may help identify trend exhaustion
  

If you find a strategy that works well with this indicator, I'd love to know. Enjoy!
