What is Lightning Futures?


In Lightning Futures, you can margin buy and sell Bitcoin by depositing margin and making a settlement, using the unit BFT.

A position in a Lightning Futures market can be closed with a counter-trade settlement prior to the maturity date. If the position is not closed by the maturity date, the position will be automatically settled at the SQ (settlement price). The SQ (settlement price) is using the Itayose* method at the time determined on the Bitcoin spot market maturity date.

One of the best parts about Lightning Futures (Bitcoin futures) is the opportunity to leverage your Bitcoin trades up to 15x.

Increase your trading efficiency and achieve better results by trading with more than your original deposit amount.

In addition, you can take a short position, allowing you to make a profit even when the Bitcoin prices drop.

Trading is open on weekends and holidays as well.

"Itayose" is a method for setting a price that matches quantitatively by repeatedly performing buy and sell orders according to a prescribed order of priority, and executing a trade with that price as the single consensus price. It is the method used for setting the SQ (settlement price) on a Lightning Futures (Bitcoin futures) trade sheet. Please see the table below for the maturity schedule for Itayose, margin settlements, etc.

Maturity schedule
  • Stop Futures trades that reached maturity date
  • Start Futures trades with new maturity dates
  • BTC spot market itayose
  • SQ (special quotation) determination by single-price auction on the BTC spot market
  • Settlement of open positions based on the SQ (special quotation) determined by the BTC spot market

The schedule is subject to change.

Order of priority is as follows.

  • Sell order
    1. (1) Market order
    2. (2) lowest price limit order
    Buy order
    1. (1) Market order
    2. (2) highest price limit order

If you have placed multiple limit orders at the same price, the orders will be executed in the order they were placed. All market orders placed before the single-price auction is determined (including orders placed prior to scheduled maintenance) will be considered to have been placed at the same time.

About Margin

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

Lightning Futures 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 details about how we handle margin, please refer to out Lightning Futures (Bitcoin futures) Terms of Use.

For rules on margin calls and sell out, please refer to Lightning Futures 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 600,000 JPY and the account used allows 10x leverage (a margin rate of 10%).
600,000 JPY * 2 BTC * 10% = 120,000 JPY

The required margin for the order is 120,000 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.
