Crude oil ETFs ordered lowest-to-highest expense ratio: https://etfdb.com/screener/#page=1&...nses&sort_by=expense_ratio&sort_direction=asc
You would need to look very carefully at what @FoggerMan said. It will take you time to understand it all but it is a very important concept. Same applies to VIX ETFs and other commodities.....
Question: So, if I want to buy one contract of May 20 WTI future, it will cost me $22,600 + commission? Is it for WTI, Blend WTI...? According to YChart, WTI on 4-20-20 was $36.98?
The May contract has expired. The front month contract is June, which is trading at ~$14 x 1,000 = ~$14,000 notional value. The current margin requirement by the CME is $6,400, meaning you would need to only put out $6,400. If the position goes against you you would need to deposit more funds. Unlike a stock, since the price can go negative, there is no limit on how much you may need to deposit so keep that in mind. Here is the CME's page for WTI: https://www.cmegroup.com/trading/energy/crude-oil/light-sweet-crude.html They also have a mini contract that is half the size: https://www.cmegroup.com/trading/energy/crude-oil/light-sweet-crude.html It sounds like you may not have much experience with futures though so I would definitely do some research before trading them (as you are doing now with this question).
Out of curiosity, are you trading oil futures and if so, how is the currebt volatility affecting you?
I don't trade oil or any energy products. There's no particular reason for that other than it's just not what I specialize in.
