Well IMO you can rule out CMC
This is how they price CASH WTI
https://www.cmcmarkets.com/en-gb/instruments/crude-oil-west-texas-cash
According to them cash wti is now mid $14 mark
That link I posted does not in any way describe what you are now buying/selling
you are trading a cash product that is now fixed to december contract and they are making
holders par 220% interest to hold their long positions
the product used to be what we know is cash or spot...just like their brent crude product still is
and traded down from high $60 to single figures in the recent fall
I bought long positions from $9 down to $7 and also bough short positions in future months contracts
some months out at double those kind of prices again with the same account. ..as sort of an arbitrage...
Anyway CMC decided to change how they define cash just for WTI but not for brent mind you
So without prior notice...they fixed spot to december contract and then charged everyone 220% for the
privillage of holding it, and they are fine with doing this...just ask them
There is now a FB page and talk of several class actions in many countries over this
Up until this I was rather happy with CMC, though I learnt not to use stops, especially when I was asleep
