7. Maintenance Margin Rules, Margin Call Rules, Sell Out Rules

Our Maintenance Margin Rules, Margin Call Rules, and Sell Out Rules are as follows:

Maintenance Margin Rules

• If the maintenance margin rate falls below 100%, the Maintenance Margin Rules will apply.
• All outstanding new orders will be revoked (cancelled) (“New orders” shall mean the orders which increase the customer's position.)
• When the maintenance margin rate is below 100%, transferring out your margin deposit from your margin accounts (Japanese yen and Bitcoin) to spot accounts, or placing new orders will be suspended.
• There may be delays in the Maintenance Margin Rules being applied. The Company will not be held liable for any losses incurred as a result of such delays.

Margin Call Rules

1. If the maintenance margin rate is below 100% at 6:00 PM (JST) every business day (including weekends and holidays), Margin Call Rule will apply and a margin call will occur.
2. All outstanding new orders will be revoked (cancelled).
3. If the margin call has not been resolved by 4:59 PM (JST) on the next business day (including weekends and holidays) after the margin call is triggered, Sell Out Rules will apply at 5:00 PM (JST). The methods of resolving the margin call are as follows.
   (1) Deposit Japanese yen or bitcoin into your margin account
   (2) Partial or complete settlement of your positions
   (3) Increase the leverage rate*

   *If the leverage rate is set lower than the maximum value, it can be raised to resolve the margin call. It will not be raised if you have selected the maximum leverage rate. As an example, if margin call rules are applied with leverage 1x and the maintenance margin rate is subsequently 55%, the maintenance margin rate will become 110% when leverage becomes 2x, and the margin call will be resolved. However, be aware that if the market price continues to fluctuate by 5% or more, the maintenance margin rate will again fall below 100%, and margin call rules may be applied at the next timing of determination of margin call.

• Please note that even if the maintenance margin rate exceeds 100% by methods other than listed above (market fluctuation, etc.), after the margin call is triggered, the margin call will not be resolved.
• If the market has changed abruptly, the Sell Out Rules is applied before the Margin Call Rules are applied.
• It may take time for the amount of the Margin Call to be reflected on the trade screen even after all or part of the Margin Call clears. If the amount is not reflected, wait for a moment and try again.
• There may be delays in the Margin Call rules being applied. The Company will not be held liable for any losses incurred as a result of such delays.

Sell Out Rules

• If the maintenance margin rate falls below 50%, or based on the Margin Call Rules, if the margin call has not been resolved by 4:59 PM (JST) of the next business day (including weekends and holidays) after the margin call is triggered, the Sell Out Rules will apply at 5:00 PM (JST).
• We will close all of your positions on Lightning FX/Futures (Sell Out order). Sell Out orders involve market orders on all positions for settlement purposes.
• Trade may not be resumed until settlement orders on all positions are finalized.
• There may be delays in the Sell Out Rules being applied. The Company will not be held liable for any losses incurred as a result of such delays.
