WTIUSD is the market symbol for West Texas Intermediate (WTI) crude oil priced in US dollars per barrel. WTI is the main US benchmark for crude, a light, sweet grade delivered and stored at Cushing, Oklahoma.
Trading WTIUSD works through an Oil CFD, a position on WTI's price movement with no ownership of physical barrels. You go long if you expect the price to climb and short if you expect it to drop, with the quote shown in US dollars per barrel and movement measured in price points.
WTI prices shift with OPEC+ supply policy, weekly US inventory data, demand expectations, and the US dollar. A common mix-up is WTI versus Brent: WTI is the US benchmark and Brent the international one, so the two carry different prices and the gap between them is watched as the WTI-Brent spread.
Suppose WTIUSD is trading at 78.00 per barrel. Expecting a fall after a large inventory build, you open a short Oil CFD position at 78.00 with 10:1 leverage.
WTI drops to 75.50 per barrel and you buy back to close.
Your gain is 2.50 per barrel on the decline (78.00 minus 75.50), before costs.
