8. Matching

How to match
The Dcoin platform system will match on the principle of price first and time first. "Buy/Go Long" is the direction of the buy order, and "Sell/Short" is the direction of the sell order.
The buy order has the highest price, the earliest time is the first in the buy order sequence, and the sell order has the lowest price, and the earliest time is the first in the sell order sequence. When the first price in the buy order sequence is greater than or equal to the first price in the sell order sequence, the deal can be matched.

What happens after the match is successful
If a buy/sell order with the same direction as the held position is successfully matched (increased position), the system will increase the position of the corresponding contract in the corresponding direction, each position is independent, calculating the average price of the position and the estimated liquidation price.

If a buy/sell order that is opposite to the held position is matched successfully (lighten up), the system will reduce the position of the corresponding contract in the corresponding direction, each position is independent, calculating the average price of the position and the estimated liquidation price.
