はじめての日経225先物
この記事は約3分で読めます。
日経225先物というと、何か危なっかしい感じで、
初心者の方には少しハードルが高そうに思われるかもしれません。
確かにネット検索すると詳細に解説されていますが、
かえって頭が混乱しかねないと逆に思います。
そこで、細かいところはさておいて、
取引する上で最低限知っておかなければならない
ルールに絞って解説したいと思います。
つまり、これさえわかればすぐに日経先物売買スタートさせられる
という内容でご案内いたします。
まずミニとラージの2種類あり、個人投資家の多くはミニを活用しています。
言葉の通り、ラージはミニの10倍のサイズで、必要な資金も10倍となるため、元手資金・必要証拠金が潤沢にある人専用（プロ仕様）なのです。
なので、日経225ミニ先物を中心にご説明すると、
例えば、現時点の日経平均（先物価格）が2万2100円とします。
ミニでは、取引金額は価格を「100倍」するので、
実際、1枚買うと221万円の銘柄を購入したことになります。
そこで、日経平均が2万2200円と100円上昇したら・・
222万円と評価されますので、1万円の含み益となります。
つまり、ミニでは日経平均（先物価格）が
100円上がれば1万円儲かる。
100円下がれば1万円損する。
ちなみにラージはミニの10倍の評価なので、
100円上がれば10万円儲かる。
100円下がれば10万円損する。
この感覚さえわかれば、明日からでも売買できます。
あとは、もう少し付け足すだけです。
①手数料
手数料は、ミニでSBI証券ですと1枚につき35円（税込38.5円）
ラージは1枚につき250円（税込275円）
いずれにせよ、安っ！取扱金額からすると無いに等しい！
そう、日経先物の手数料額は気にするに値しないのです。
②取引時間
取引時間は日中、夜間と2場所あり、夜間ならサラリーマンの方でも参戦可能！
日中8：45-3：15
夜間16：30-5：30
③限月とSQ
限月とは購入した日経先物の締め切りの月のことです。
そう、日経先物には必ず限月（締切り月）が存在します。
そして、限月（締切り月）の第2週の金曜日の朝の寄り付きの
日経平均株価を特別清算指数SQ値として割り出し、
限月の第2金曜日(SQ日)が来ると、保有ポジションはSQ値で清算(強制決済)されます。
ですので、最初に購入する前に、いつまでに決済するのか決めた上で、
購入する必要があります。長期保有するつもりなら、限月を遠い月にします。
一般には売買ボリュームが厚い直近限月か翌限月で取引で参戦します。
④必要証拠金
必要証拠金を最初に差し入れされすれば、取引価額全額の資金を必要とせず、取引を行なうことができます。
必要証拠金は相場変動に応じて、
変動が大きくなると多くの証拠金が求められ、変動が小さいと証拠金は減ります。
直近ですと1枚当たり、ミニが8万7000円、ラージが87万円です。
なので、そもそもミニをやりたいなら、約10万円の元手資金は用意しないといけません。
元手5万円では日経先物の売買はスタートできません。
しかも、必要証拠金は常にキープしていないといけません。
評価損が発生すると追証とよばれる追加証拠金を
追加証拠金の発生日の翌営業日までに差し入れる必要があります。
上記の例で、10万円の元手資金でミニを1枚買ったとして、
日経平均（先物価格）が300円値下がりしたら、
3万円の含み損なので、証拠金は10万-3万＝7万円の評価となり、
ミニの必要証拠金8万7000円満たなくなるため、
追加証拠金を1万7000円翌営業日までに差し入れないといけなくなります。
間に合わないと強制決済されて売買終了となります。
なので日経平均（先物価格）の変動を1000円見込むなら、
この場合18万7000円、おおよそ20万円は用意しておかないといけないという事です。（2000円の変動を見込むなら30万円の用意がいる。）
なので、現実的には10万円の元手資金ではなく20万円は最低用意しないと、
ミニを落ち着いて売買できないという事です。
この様に、限月とSQ、必要証拠金さえ注意すれば、
あとは普通の株と同じような感覚で取引できます。

This was a fantastic piece, thank you for sharing it online. We are going camping at Doughton Park tomorrow. It seems that there are more cut-backs in that park every year recently. A large portion of the campground has been closed for a few years now, including the campfire circle and the educational programs that went on at that circle. The Brinegar Cabin is no longer staffed every day, and there are less rangers working that park all around. We will go there as long as any of the park is open to us because we love the area, the people, the scenery and everything else that place has to offer. Whether car camping in Doughton, or fly fishing and backpacking into Basin Cove, every minute spent there is wonderful and all who love it should do all we can to keep it thriving. Torrie Dare Pagas

My beautiful daughter died on October 30, 2016. She is the oldest of our seven children and such an amazing and special person. She was truly beautiful inside and out. We have learned so much about her since she died. I thought I knew everything in the world about my precious child but we have learned so much about her love and compassion for others since she died. Hundreds and hundreds of people have contacted us and posted about her and about the beautiful things she did for them over the years. She reached out to so many people when they were going through difficult times and needed a friend, she loved everyone unconditionally, she always stood up for those who needed protection or were being discriminated against. I could not be more proud of my beautiful daughter. She was loved by so many people. I only wish she had known the difference she made in the lives of so many others before she died. She was a social work major in college in her junior year and the school of social work said she truly had the heart of a social worker. She always has since she was a tiny toddler. Such a special child, always. Wendi Jack LeDoux
