BTCUSD vs S&P500 (Daily)

This script plots an RSI of the difference between the BTCUSD (FTX) and S&P 500 (FRED) prices, useful to see how the BTCUSD price correlates to the stock market.

This works in the daily timeframe only (because the S&P 500 can only be sampled on this timeframe). You can try lower timeframes but they will be gapped / interpolated.
