Somehow this is becoming a reality, stocks and crypto goes down and same in oil prices. Then all of a sudden BTC gets a slight increase and same goes to oil price, but not literally with stocks. This is just my opinion, but as far as I can see, these are really related with each other.
In the past, I have noticed a correlation between the stock market performance and the BTC exchange rates. But I don't think that there is any relation between oil prices and the Bitcoin exchange rate. I have checked the charts by overlaying these two, and I couldn't notice any such relation. But BTC exchange rates goes up whenever there is a spike in the stock market.
