In April 2020 WTI crude oil futures price gone negative.
I trade crude oil CFDs using eToro and IqOption. On these platforms oil prices were different. On eToro the lowest price was around 7.3 while on IqOption it was around 8.4.
There's yet another picture on TradingView symbols:
USDWTIwere at 0
OIL_CRUDEwas at 9.8
Who can I trust? How CFD brokers get their prices? Can oil CFD go negative?
