### 1. How does Cross Margin/Isolated Margin work ?

When Kine goes live an asset, base on the financial nature of the asset, Kine will decide whether it supports cross margin mode, all assets support isolated margin mode automatically. Positions of cross margin assets are placed in "Cross margin account" after opened. The leverage of those positions will be calculated together as well as liquidated together once the predefined leverage limit were hit. User can switch to isolated mode for each asset, in which case the leverage and liquidation will be accounted and executed for this asset only.

### 2. What does "Asset" or "Debt" mean ?

To achieve cross asset margining and meantime simplifying the calculation, Kine therefore introduced "Asset" and "Debt" concept.
Asset is the sum of long position usd value.
Debt is the absolute sum of short position usd value.
Equity = Asset - Debt
Leverage = Asset / Equity
eg: John has 10000 kUSD transferred to cross margin account and then bought 2 BTC at 50000 USD, 2 ETH at 2000 USD. Now his account balances are as following: kUSD = 10000 - (50000 * 2 + 2000 * 2) = - 94000 BTC = 2 ETH = 2 So, statistics below: asset = 2 * 50000 + 2 * 2000 = 104000 debt = | - 94000 | = 94000 equity = 104000 - 94000 = 10000 (as price has not moved) leverage = 104000/10000 = 10.4

### 4. Where does the price indices come from ?

Kine reads the realtime price feed from Coinbase, Kraken, Bitstamp and Bitfinex, for each asset, there is a weight combination of the four sources ultimately generates the index price.

### 5. How does liquidation work in Kine exchange ?

Leverage of each cross margin and isolated margin account is calculated in realtime, when it hits leverage limit , the kUSD balance as well as other asset(s) will be cleared.
eg: The market has moved against John's favor, now BTC at 45000 USD and ETH at 2475 USD . So, statistics below: asset = 2 * 45000 + 2 * 2475 = 94950 debt = | - 94000 | = 94000 equity = 94950 - 94000 = 950 leverage = 94950/950 = 99.95 Now as the liquidation leverage is set at 99x , John's cross margin account will be liquidated.

### 6. What is Auto Deleveraging(ADL) ?

When a trader's position triggered liquidation, it will be taken over by Kine liquidity pool. Meantime, if after the take over, Platform Net Position Ratio hit limit, then the over exposed position will need to be cleared by reducing equivalent amount of opposite position from all other traders. The process of reducing equivalent amount of opposite position is called Auto Deleveraging(ADL).

### 7. What is the ADL priority ranking rule ?

Essentially, higher position PNL percentage and leverage contributes to higher ADL priority. Below is the calculation:
Ranking = PNL Percentage * Leverage (if PNL percentage ≥ 0) PNL Percentage / Leverage (if PNL percentage < 0)

### 8. How to use condition order in Kine Exchange?

Condition order is equivalent function of the limit order function in traditional exchanges. User first sets the trigger price and buy/sell amount when placing an order. When the market price hits the preset trigger price, system will immediately execute the order at market price.

### 9. How does Stop Loss/Take Profit function works?

After opens a position, trader can set a take profit or stop loss on each of his/her positions. When market price hits the stop-profit price or the stop-loss price, system will immediately close the specified amount the of position at market price. For short positions, the take profit price needs to be lower than the position average open price, and the stop loss price needs to be higher than the average open price. For long positions, the take profit price needs to be higher than the average open price, and the stop loss price needs to be lower than the average open price.

### 10. Why supports USDC/USDT as margin currency?

Kine was originally designed to support kUSD as margin currency only , but for traders who do not Stake on the Kine Dapp, they have to buy kUSD before trading. With supporting on USDC/USDT margin, USDC or USDT holders can participate in trading directly. At the same time, we also provide margin currency switch option, which is convenient for existing users to adopt to the new multi currency margin framework.
