About Margin

Before being able to trade on Lightning FX, it is necessary to make a margin deposit.

Lightning FX regularly checks the status of margin deposits. If the retention rate of your deposit drops below a fixed level (maintenance margin), it will trigger a "margin call" or "sell out".

For more information on the retention rate of earnest money set forth by bitFlyer, please refer to the Fees & Taxes page (https://bitflyer.jp/commission)

For rules on margin calls and sell out, please refer to FX trading rules.

When placing a new order*, what is the necessary deposited amount for the order? The method below will show you how to calculate this. (The calculation below is based on a maintenance margin of 10%). * A new order is one that increases a customer's risk.

Example: An order/open position has been made for 2 BTC. 1 bitcoin is worth 135,000 JPY and the account used allows 10x leverage (a margin rate of 10%).
135,000 JPY * 2 BTC * 10% = 27,000 JPY

The required margin for the order is 27,000 JPY.

Additionally, the maintenance margin can be determined using the method below.

  • Profit and loss (valuation), required margin, etc. are combined across Lightning FX/Futures markets.

    Please note that positions on different markets do not offset each other in calculation of required margin.
