I want to buy Oil, what is the symbol, exchange and contract?

$20 is still ok, i will buy it .. how to buy ?

 

This just shows you shouldn't be trading anything. Look up what a fund/ETF is.

 

Open a futures account.

 

Oil is very deceiving. The June contract Looks like it was around the price it is today in mid march. The $11 oil will be forgotten tomorrow when the June contract is the front month.

 

Oil hit $11 per barrel. Would it strike down from $10....

 

you need to open a futures account and if you never traded futures before, i recommend talking to a broker first to understand some of the ins and outs of futures trading.
Here are two good starting points:

I have a future account

 

And four hours after your post Oil is at $10 and change.

May '20 CL: -$7.69 last

Sept '20 CL: -$0.96 last

 

LOL - there will be a million people looking to buy oil "cheap" at 10 usd. Maybe @Baron can place a banner educating people who has not traded oil before about contango, storage and the lack of free lunches.
