Hi everyone,
Sorry if it is obvious, but I'm completely lost. Consider this:
`def main():
symbols = ["AAPL", "GOOG", "NVDA"] # ! works
# symbols = ["BTC-USD","ETH-USD"] # ! works
# symbols = ["BTC-USD","ETH-USD"] # ! works
# symbols = ["BTC-USD","ETH-USD", "XMR-USD", "ADA-USD"] # ! works
# symbols = ["SPY", "QQQ", "^FCHI"] # ! doesn't work
# symbols = ["AAPL", "GOOG", "FB"] # ! doesn't work
# symbols = ["AAPL", "GOOG", "SPY"] # ! doesn't work
As per the comment on each symbols = line: some will succeed, others will fail with
ValueError: Symbols have mismatching columns.What am I missing ?! Many thanks.
