插件示例

插件可以在一段时间内执行代码，完成一些简单的操作，例如冰山委托、挂单、撤单、计算等。插件用return返回结果，返回表格、图表对象时直接显示为表格、图表。下面是两个例子，更多范例可以在策略广场中查找，例如逐笔小量买入/卖出。

返回深度快照

以表格显示当前盘口前15档：

            javascript
            
            
// 返回深度快照
function main() {
    var tbl = {
        type: 'table',
        title: '深度快照 @ ' + _D(),
        cols: ['#', 'Amount', 'Ask', 'Bid', 'Amount'],
        rows: []
    }
    var d = exchange.GetDepth()
    var n = Math.min(d.Asks.length, d.Bids.length, 15)
    for (var i = 0; i < n; i++) {
        tbl.rows.push([i, d.Asks[i].Amount, d.Asks[i].Price + '#ff0000', d.Bids[i].Price + '#0000ff', d.Bids[i].Amount])
    }
    return tbl
}

画跨期差价

期货交易所对象上，取季度合约与当周合约的5分钟K线，画出收盘价差：

            javascript
            
            
// 画跨期差价
var chart = {
    __isStock: true,
    title: {text: '差价分析图'},
    xAxis: {type: 'datetime'},
    yAxis: {
        title: {text: '差价'},
        opposite: false
    },
    series: [
        {name: "diff", data: []}
    ]
}

function main() {
    exchange.SetContractType('quarter')
    var recordsA = exchange.GetRecords(PERIOD_M5)
    exchange.SetContractType('this_week')
    var recordsB = exchange.GetRecords(PERIOD_M5)

    var n = Math.min(recordsA.length, recordsB.length)
    for (var i = 0; i < n; i++) {
        var a = recordsA[recordsA.length - n + i]
        var b = recordsB[recordsB.length - n + i]
        chart.series[0].data.push([a.Time, a.Close - b.Close])
    }
    return chart
}
