Describe bug

Hello, in the 1 or 5 minute history, for example of 'BTC-USD' often the volume is 0. There seems to be no negative volume at all. Could it be that it is failing volume and whenever it has to be negative a 0 is stored? I have tried both with 'repair' to True or False. Thanks.

Simple code that reproduces your problem

import yfinance as yf stock = yf.Ticker('BTC-USD') historical_prices = stock.history(start='2024-05-09', end='2024-05-10', interval='5m', repair=True)
