The Nikkei 225 Mini will be traded using a trading method called futures trading. Futures trading is based on the promise to buy and sell in-kind (for example, commodities, stocks, currencies, etc.) at a pre-determined price at the present on a pre-determined date in the future. Assuming that the present is March, we will make a promise to buy at the Nikkei Stock Average of 14,000 yen in May, two months later, and we will carry out trading transactions based on that. The Nikkei 225 Mini deals with the Nikkei Stock Average, not stocks or currencies. When trading futures on the Nikkei 225 Mini, we use the Nikkei Stock Average, a number that does not exist as a stock. Depending on how you look at it, it can be called a virtual stock trading. The unit used for trading is 1,000 times the average stock index for the Nikkei 225 and 100 times for the Nikkei 225 Mini. The future predetermined days for the Nikkei 225 Mini are the second Friday of March, June, September and December, and these four months are called contract months. If you keep your position even after the contract month, it will be settled at the value of SQ (Special Clearing Index) the day before the second Sunday. At that point, it will be forcibly settled regardless of whether it is a loss or a profit. Of course, you don’t have to hold the position until the last day, and you can make a settlement transaction at any time before that. The Nikkei 225 Mini futures contract is carried out under such a promise.
