AirFX: A service where you can make highly-leveraged trades with with the same feeling as spot trading.
EPS: EPS is a structure that causes a forced account settlement if there is a possibility of a loss on your margin relative to other positions. This can occur if you hold a position with unrealized gains. This reduces risk and allows you to make transactions without incurring losses on your margin.
Swap Handling Fees: This is a fee that is incurred if there is a difference between the value of actual commodities and AirFx’s value. The highest value for Swap Handling Fees is ±0.375%. This is calculated not from your margin but based on the position you currently hold. Calculating this from your margin would be the same as a Credit Transaction.
Please refer to “AirFX Swap Handling Fee Calculation Method” for more information.
*The valuation of gains or losses is calculated from the orders listed on the board. Therefore, you will always momentarily start at a negative value when beginning to hold a position.
*If your spread becomes too large, a forced sell off will occur from the position that you currently hold. As a result, you cannot make orders that would cause your margin maintenance ratio to go below 70%.
*Swap fees are calculated from the position you currently hold. However, this could cause an immediate loss, so your margin maintenance ratio will fluctuate.
