How Trading Works

Taste Markets uses perpetual contracts - positions with no expiry date that you can hold as long as your margin allows.

Opening a Position

Your entry price is determined by the current oracle price at execution time.

Fees

Fee TypeRate
Open / Close0.35%
Liquidation1%
Borrow feeVariable

Fees are deducted from your collateral.

Borrow Rate

Holding a leveraged position incurs a borrow rate that accrues over time. The rate depends on pool utilization:

  • Below 80% utilization: Lower rate (~0.008% per hour)
  • Above 80% utilization: Higher rate (~0.012% per hour)

This incentivizes liquidity providers and keeps pool utilization healthy.

Liquidation

If the market moves against your position far enough that your remaining collateral approaches zero, your position is liquidated:

  • The position is automatically closed
  • A 1% liquidation fee is charged
  • Remaining collateral (if any) is returned to you

Higher leverage means a tighter liquidation price. You can view your liquidation price for each position in the Positions panel.

Increasing a Position

You can add collateral to an existing position to increase its size or reduce liquidation risk, without closing and re-opening.

Closing a Position

Close a position at any time to realize your PnL. The exit price is based on the current oracle price, minus the close fee.

PnL Calculation

  • Long: PnL = Position Size × (Exit Price − Entry Price) / Entry Price
  • Short: PnL = Position Size × (Entry Price − Exit Price) / Entry Price

Fees and accumulated borrow costs are subtracted from your final PnL.
