Margin Call Rules

If the maintenance margin rate falls below the level prescribed by bitFlyer, Margin Call Rules apply. However, if the market has changed abruptly, the Sell Out Rules is applied instead, and a loss in excess of the margin amount may occur. In this case, the customer will need to add funds promptly to resolve the lack of funds. Margin Call Rules are as follows:

  1. All outstanding new orders will be revoked (cancelled). (“New orders” shall mean the orders which increase the customer's risk.)
  2. Please deposit additional margin funds until 17:00 of the third bank business day, so that the maintenance margin rate is at a level greater than that set by bitFlyer. If the maintenance margin rate is still below the level prescribed by bitFlyer at 17:00 on the third bank business day after it fell below the prescribed level, the following Sell Out Rules will apply.

Sell Out Rules

If the market changes suddenly, even if Sell Out Rules are applied, there may be a loss in excess of the amount of margin. In this case, the customer will need to add funds promptly to resolve the lack of funds.

The Sell Out Rules are as follows:

  1. All outstanding new orders will be revoked (cancelled).
  2. If as a result of (1), the maintenance margin rate is still below the level prescribed by bitFlyer, we will sell all of your positions on Lightning Futures (Sell Out order) to make a settlement.
