今晚的美股又跳水惹

假如我們預計要掛個價格出去但發現價格不如預期的往反方向走，該怎麼辦呢？

當然是趕快抽單或是做逆勢單囉

首先 先設定好要掛的單子(order)與送出單子(trade)

contract = api.Contracts.Futures.TXF['TXF202110']
order = api.Order(
    action='Sell',
    price=17760,
    quantity=1,
    price_type='LMT',
    order_type='ROD', 
    octype=sj.constant.FuturesOCType.Auto,
    account=api.futopt_account
)
trade = api.place_order(contract, order)

回傳

OrderState.FOrder {
    'operation': {
        'op_type': 'New', 
        'op_code': '00', 
        'op_msg': ''
    }, 
    'order': {
        'id': '02c347f7', 
        'seqno': '956201', 
        'ordno': 'kY00H', 
        'action': 'Sell', 
        'price': 17760.0, 
        'quantity': 1, 
        'order_cond': None, 
        'order_type': 'ROD', 
        'price_type': 'LMT', 
        'market_type': 'Night', 
        'oc_type': 'New', 
        'subaccount': ''
    }, 
    'status': {
        'id': '02c347f7', 
        'exchange_ts': 1625729890, 
        'modified_price': 0.0, 
        'cancel_quantity': 0
    }, 
    'contract': {
        'security_type': 'FUT', 
        'code': 'TXF', 
        'exchange': 'TIM', 
        'delivery_month': '202107', 
        'strike_price': 0.0, 
        'option_right': 'Future'
    }
}

今天我們要取消送出的單

api.update_status(api.futopt_account)
api.cancel_order(trade)

OrderState.FOrder {
    "operation":{
        "op_type":"Cancel",
        "op_code":"00",
        "op_msg":""
    },
    "order":{
        "id":"02c347f7",
        "seqno":"956201",
        "ordno":"kY00H",
        "action":"Sell",
        "price":17760.0,
        "quantity":1,
        "order_cond":None,
        "order_type":"ROD",
        "price_type":"CXL",
        "market_type":"Night",
        "oc_type":"New",
        "subaccount":""
    },
    "status":{
        "id":"02c347f7",
        "exchange_ts":1625730789,
        "modified_price":0.0,
        "cancel_quantity":1
    },
    "contract":{
        "security_type":"FUT",
        "code":"TXF",
        "exchange":"TIM",
        "delivery_month":"202107",
        "strike_price":0.0,
        "option_right":"Future"
    }
}

這樣就可以取消送出的單，假如已經成交的單子就沒辦法了，要趕快設停損

當然也有很多右側交易者摩拳擦掌，要抄底...

看起來最近還要震盪一陣子
