The Cross-Margin Mode with Multiple Cryptocurrencies trading accounts is a new trading system launched by Coincall for its users. It supports trading various derivatives using multiple currency assets in a single account. Under this mode, users can trade perpetual contracts and options contracts simultaneously. All currency assets of the user will be converted into USD Stable Coins value for opening and holding margin.
Compared to the account types of other exchanges in the market, this will provide a great convenience for users' trading, eliminating the need to transfer funds between multiple accounts. All positions of the user share the same margin, and the profits and losses of each position can offset each other, effectively improving the user's capital utilization.
Coincall provides the Standard Margin （SM）account mode. Under the SM mode, the margin of each position is calculated independently, and the account margin is obtained by adding them up.
Options contracts belong to margin trading, and users need to understand the concepts of initial margin and maintenance margin before trading.
Initial margin (IM) is the minimum margin required for opening a position, including commission opening IM and holding IM.
Maintenance margin (MM) is the minimum margin required to maintain a position. If the account margin falls below the maintenance margin level, the position will be liquidated.
Explanation of the concept of account asset
Margin Balance - IM - Options/Futures Commission Order Freeze Fee - (Withdrawal Freeze + Withdrawal Freeze Fee)
|Margin Balance||Net Asset Value - Valuation of Sell Options - Valuation of Buy Options|
|Net Asset Value||
Deposits - Withdrawal - Withdrawal fee + Realized PnL of futures and options + Settlement PnL on options expiration - Options/futures trading fee - Option exercise fee - Options/futures liquidation fee - Futures position funding fee + Unrealized PnL on options + Unrealized PnL on futures
|Unrealized Profit and Loss（Unrealized PNL）||(mark price - average price of open positions) * position quantity * buy and sell direction; buy = +1, sell = -1|
|Realized Profit and Loss (Realized PNL)||
(Close price - average price of open positions) * closing quantity * buy and sell direction; buy = +1, sell = -1
|Option expiration settlement profit and loss||
Exercise settlement income and expenses - opening average price * pre-exercise position quantity * buy/sell direction; buy = +1, sell = -1
|Option exercise settlement income and expenses||For at-the-money and out-of-the-money options, not exercising at expiration, exercise PnL = 0.|
|For in-the-money options, the exercise profit and loss = (settlement price - exercise price) * pre-exercise position quantity * buy/sell direction * Call or Put; buy = +1, sell = -1; Call = +1, Put = -1|
The settlement price is the arithmetic average of the underlying index price 30 minutes before the expiration exercise
|Futures Position Funding Fee||futures position quantity * funding rate|
When the funding rate is positive, the long pay the short; when the funding rate is negative, the short pay the long; the exchange platform does not charge a commission
|Sell option valuation||Mark Price * position quantity, position quantity is negative|
|Buy option valuation||Mark Price * position quantity, position quantity is positive|
Under SM, sell option holding IM + sell option open order IM + buy option open order IM + futures holding position IM + futures open order IM
|Maintenance Margin||Under SM, sell option holding MM + futures holding MM|
|Initial Margin Rate||Total IM/Margin Balance|
|Maintain margin rates||
Total MM/ Margin Balance
