What is Lightning FX?

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.com/en-jp/commission)

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