Just vibe-coded the real-time BTC/gold ratio in python, in case anyone else is interested:
# Bitcoin-to-Gold price ratio (BTC-USD / GC=F) from 2022-01-01 to today.
# Requires: pandas, yfinance, matplotlib
import datetime as dt
import pandas as pd
import yfinance as yf
import matplotlib.pyplot as plt
start = dt.datetime(2022, 1, 1)
end = dt.datetime.now()
tickers = {"Bitcoin": "BTC-USD", "Gold": "GC=F"} # GC=F = COMEX gold futures
raw = yf.download(
list(tickers.values()),
start=start,
end=end,
interval="1d",
progress=False,
auto_adjust=False,
)["Close"].rename(columns={v: k for k, v in tickers.items()})
# forward-fill gold so weekends & holidays have a price
prices = raw.ffill()
ratio = prices["Bitcoin"] / prices["Gold"]
ax = ratio.plot(figsize=(10, 6), title="BTC / Gold Price Ratio")
ax.set_xlabel("Date")
ax.set_ylabel("BTC price รท Gold price")
plt.tight_layout()
plt.show()
