I'm mostly a crypto trader (during spare time)but sometimes looking at other markets I've indeed bought some crude oil units near the bottom, like other said this is potentially a temporary drop tighly connected with the covid restrictions and the very high price for stocking unsold barrels. As soon restriictionsare gradually removed we will probably see a rise in price, those are the fundamentals. May futures gone crazy with negative values during a sort of spiralingbearish bid auction, I suggest to stay away from them and stick only on derivatives. I do technical analysis usingEWtheoryand advanced volatility probability, I can share a couple of charts if you like
