Contracts refers to the standardized trading products designed by crypto asset contract trading platform BFX. Both buyers and sellers should follow the specifications and rules set for each contract and pay a certain percentage in USDT as margins.

Underlying Asset

Underlying asset refers to the benchmark asset of each product. For example, the underlying asset for Bitcoin contracts would be Bitcoin Price Index.

Margin Trading

Maintenance margin is the minimum amount of equity that must be maintained in a margin account in order to maintain one’s position. This creates a gearing effect for the contract.

Open a position/Open positions

Taking a position is the action where investors buy (taking a long position) or sell (taking a short position) a certain amount of contracts. Just like in spot trading buyers or sellers must have a counterparty in the opposite position.

For example, if user A want to buy 10 Bitcoin contracts and user B wishes to sell 10 of his contracts, then they will be matched with A taking a long position and B taking a short one.

Close a position/ Close positions

Liquidation means when users trade against their original position, in order to stop losses from unfavorable price movements.

Mandatory Liquidation Trigger Price

Mandatory Liquidation Trigger Price is the price which will be forced to place order by the system at the blow up price when your position margin is insufficient. When the remaining amount of the loss is less than 20% of the margin, the Mandatory Liquidation will be triggered, and will entrust the settlement with the blow up price.

Strike Price

BFX prices are automatically matched by our trading computer with priorities given to the optimization of prices, time, and to liquidations.

Long Position, Short Position

When a user believes the value of a certain asset will increase, the action of buying those contracts is called taking a long position.

When a user believes the value of a certain asset will decrease, the action of selling those contracts is called taking a short position.

For example: User A buys 10 BTC Contracts, suppose user B sells 10 BTC Contracts at the same time, the trade was executed at $8,000 with A taking long position with 10 contracts and B taking short position with 10 contracts. In the event of Bitcoin prices rose to $8,500 A liquidated 5 of his/her contracts and B bought 5 contracts. After this trade A is now taking long position with only 5 contracts, and B IS taking short position with only 5 contracts.

Hedging in futures trading is where a party with interested tied to a certain asset uses the futures contract market to limit his/her exposure to risks.

39、Let’s tale Bitcoin contracts as an example:

Using futures contracts to hedge for Bitcoins refers to parties like Bitcoin miners, BTC Payment providers and long term holders utilizes the futures contract market to limit his/her exposure to risks. It can be further dividend into long hedge and short hedge.

  1. The seller's selling period hedge:the miners who produce Bitcoin should do a sell hedging transaction on Bitcoin virtual contract trading market to prevent prices from falling and affecting the mining revenue when in the high price. After that, even if the Bitcoin price plummets, it will not have too much impact on profits;
  2. The operator's hedging: operators who will buy Bitcoin in the future can do a sell hedging transaction if they are afraid that they will get lower price Bitcoin as they believe the current price is higher; operators who will pay Bitcoin in the future can do a buy hedging transaction if they are afraid that they will pay more as they believe the current price is lower, but they do not want to buy Bitcoin with a lot of money now.;
  3. The holder's hedging: If someone temporarily holds a large amount of Bitcoin for some reason, he/she fears that the price will fall or the assets will shrink for the reason of Bitcoin industry in the future, he/she can throw it up and do a sell hedging.

Spread trading

Hedging is a low-risk investment behavior. The participation of spread traders is conducive to the improvement of market pricing mechanism. The formation of a market price mechanism is essential. Spread tradings are divided into calendar spread, intercommodity spread, cross-time spread, and cross-market spread. A brief explanation is as follows:

  1. Intercommodity spread refers to the use of price differences between two different but interrelated contracts for arbitrage.

    Buys (sells) a contract for a certain delivery month and sells (buys) another contract with related products in the same delivery month. For example, there is a price difference between Bitcoin and Litecoin, and investors can use the ratio change relationship between the two coins to make intercommodity spread.

  2. Cross-time spread refers to arbitrage with the price difference of Bitcoin contract and cash commodity

    Cross-time spread refers to arbitrage with the price difference of the underlying contract price and spot price

    In theory, the contract price is the future price of a target product, and the spot price is the current price of a target product. According to the same price theory in economics, the gap between the two is the “basis difference” (basis difference = spot price - contract price), which should be equal to the holding cost of the product. In Bitcoin trading, bitcoin's holding cost are mainly reflected in transaction fees.

  3. Cross-market spread is to arbitrate with different contract prices in different exchanges of a underlying specific product.

    The arbitrage cost mainly refers to transaction fees. It should be noted, however, that if the delivery underlying assets of the two contract markets are not completely homogenous, there may be a difference.
