Crude Oil Perpetual · CLUSDT

About Crude Oil (CL)

Crude oil (CL, WTI) is the most actively traded energy commodity and a barometer for global growth and geopolitics. The CL market on Aster is a 24/7 perpetual with no expiry to roll, priced from a third-party oracle feed rather than from a futures exchange directly.

Trading CL Perpetuals on Aster

On Aster, CL trades as the 24/7 USDT-margined CLUSDT perpetual: a contract with no expiry date, where your collateral and your profit or loss are both settled in USDT rather than in CL itself. Leverage runs up to 50x on the standard order-book market, and funding is exchanged between longs and shorts every eight hours to keep the contract price tracking its index. Because a perpetual never delivers the underlying, the CL market stays open around the clock, including the nights, weekends and holidays when the underlying market is shut. The instrument itself is issued by a third party and its price comes from a third-party oracle feed rather than from Aster. Orders can be placed openly or through Aster's encrypted hidden orders, which keeps size out of the public book until the moment it executes.

How the CLUSDT Perp Differs From Owning CL

Owning CL exposure the traditional way means a brokerage account, market hours and, for commodities, a dated futures contract that eventually expires. The CLUSDT perpetual replaces all of that with a USDT-margined position you open from a wallet. That difference has three practical consequences. Going short is as easy as going long, so a falling CL price is something you can trade rather than sit out. Position size can exceed collateral, up to 50x, which magnifies losses at exactly the same rate it magnifies gains. And funding is paid or received every eight hours for as long as the position stays open, a running cost that someone simply holding CL never encounters.

Fees and Leverage on the CLUSDT Market

Aster charges 0% maker and 0.04% taker on USDT-margined perpetuals, so adding liquidity to the CLUSDT book costs nothing and taking it costs 0.04% of notional. Two savings stack on top of that: paying fees in ASTER takes another 5% off at the point of trade, and signing up with referral code MMTz04 returns 5% of the fees you pay as a rebate Aster calculates daily and credits the next day. Leverage on CL is capped at 50x on the standard perp. Leverage does not change the fee rate, but it does change the notional those fees are charged against, so a 50x position pays fifty times the fee that the same collateral would pay unlevered. The full tier structure is in our full Aster fee schedule.

What to Know Before Trading CL

Three things decide whether a CL position survives. Funding is the first: the eight-hourly payment runs positive or negative depending on which side is crowded, and over days rather than minutes it compounds into a real drag on a held position. Liquidation is the second: at 50x, a move of roughly 2.0% against you consumes the margin backing the trade, before fees are counted. Liquidity is the third: depth on CLUSDT varies by hour, and a market order sized past the visible book fills at progressively worse prices, which is the situation limit orders and hidden orders exist to handle. Set the stop before you open the position rather than after, and treat the leverage slider as a risk control rather than a way to buy more.
