Glossary of Terms

Definitions of key terms used across Yellow.pro.

Key terms used throughout Yellow.pro and this documentation.

Account Balance (Yellow Wallet)

For Google Sign-in users, the main balance where deposits first arrive and from which withdrawals are made. Funds must be transferred to the Trading Account before trading. Also accessible on Yellow.com. External wallet users do not use Account Balance. See Understanding Your Balances.

ADL (Auto-Deleveraging)

The mechanism that settles liquidations on Yellow.pro: a liquidated position is matched against opposing traders, whose positions are partially closed. Priority is highest for the most profitable, highest-leverage positions on the opposite side. See Cross-Margin Risk & ADL.

Available Balance

Funds you can use right now — for new orders or withdrawals. Equals total balance minus funds locked In Orders or committed as position margin.

Bankruptcy Price

The mark price at which your account equity reaches zero. It sits just beyond your liquidation price, and is the price your position is force-settled at during liquidation. See Liquidation & Mark Price.

Base / Quote Currency

In a pair like ETH-USDT, the base currency is the asset being bought or sold (ETH) and the quote currency is what you pay or receive (USDT).

Cross Margin

The margin mode used on Yellow.pro perpetuals, where your entire available balance is shared collateral for all open positions. See Margin & Leverage.

Funding Fee

A payment exchanged between long and short perpetual traders (usually every 8 hours) to keep the contract price near the market price. Not collected by Yellow.pro. See Funding Fees Explained.

Leverage

A multiplier that lets you open a position larger than your margin (e.g. 10x). Amplifies both gains and losses. See Margin & Leverage.

Limit Order

An order to buy or sell at a specified price or better. Fills only at that price or better, and may not fill at all. See Order Types.

Liquidation

The automatic closure of a position when your account can no longer meet maintenance margin (margin ratio reaches 100%). See Liquidation & Mark Price.

Liquidation Price

The estimated mark price at which your account would be liquidated — where your equity falls to the maintenance margin level. In cross margin it moves with your PnL, positions, and balance. See Liquidation & Mark Price.

Maintenance Margin

The minimum margin required to keep a position open. If your effective margin falls below it, liquidation is triggered. On current markets the maintenance margin rate is a flat 0.5% of position notional.

Maker / Taker

A maker order adds liquidity by resting in the order book; a taker order removes liquidity by filling immediately. Maker fees are lower. See Trading Fees.

Margin Ratio

A real-time indicator of how close your account is to liquidation. At 100%, liquidation is triggered. See Margin & Leverage.

Market Order

An order that executes immediately at the best available price. Subject to slippage. See Order Types.

Mark Price

A fair-value price derived from external reference data, used to calculate unrealized PnL and liquidation — instead of the last traded price — to reduce manipulation. See Liquidation & Mark Price.

Network Fee

A blockchain transaction fee (currently Ethereum) for processing deposits and withdrawals on-chain. Set by the network, not Yellow.pro. See Withdrawal Network Fees Explained.

Perpetual Account

A separate balance used only for perpetual futures positions. Funds must be transferred here before opening perpetual positions, and cannot be withdrawn directly. See Understanding Your Balances.

Perpetual Contract

A derivative that tracks an asset's price with no expiry date. You never own the underlying asset. See What is Perpetual Trading?.

PnL (Realized / Unrealized)

Profit and Loss. Unrealized PnL is the current gain/loss on an open position (changes with the mark price); Realized PnL is locked in when you close. See Understanding PnL.

Position (Long / Short)

Going long profits when the price rises; going short profits when it falls. See Long, Short & Hedge Mode.

In Orders

The balance state for funds locked by active open orders (and, on Spot, by a withdrawal that's still processing). They return to Available when the order is filled or cancelled. On Perpetuals, funds can be In Orders too, but there is no withdrawal step.

Spot Trading

The direct exchange of one asset for another at the current market price — you own the asset you buy. See What is Spot Trading?.

Stop Limit / Stop Market

Conditional orders that activate at a trigger price, then submit a limit order (stop limit) or a market order (stop market). See Order Types.

Tick Size / Step Size

Tick size is the smallest allowed price increment; step size is the smallest allowed quantity increment for a market. Orders that don't align are rejected.

Trading Account (Spot Account)

The balance where Spot trading takes place. For external wallet users, deposits arrive here directly. See Understanding Your Balances.

Time in Force (TIF)

How long an order stays active before it's cancelled. GTC (Good 'Til Cancelled) rests until filled or cancelled — the default for limit orders; IOC (Immediate Or Cancel) fills what it can immediately and cancels the rest; FOK (Fill Or Kill) must fill completely and immediately or not at all. Market orders are always IOC. See Order Types.

Two-Way Mode (Hedge Mode)

A position mode that lets you hold a long and a short on the same pair simultaneously — currently the default on Yellow.pro. One-Way Mode will be added later. See Long, Short & Hedge Mode.

VIP Tier

Your fee level, set automatically by 30-day trading volume or your $YELLOW balance. Higher tiers pay lower maker/taker fees. See VIP Tiers & Fee Discounts.

$YELLOW

Yellow.pro's native token. Holding a 24-hour average in your Trading Account qualifies you for higher VIP tiers and lower fees. See $YELLOW Token & Fee Discounts.
