商品期货多品种R-Breaker策略

R-Breaker是一种短线日内策略,因为策略没有用到指标,没有指标周期之类的参数。策略的触发条件完全是通过价格计算出来的支撑线、阻力线。避开了指标参数对于行情的拟合问题,并且模型原理非常简单,对于市场各种行情适应性较强。虽然说策略实盘不一定效果出众,但是也可以作为一个学习研究方向思考策略设计。

策略原理

  • 支撑线、阻力线算法 计算这些数据的时候用到三个数据分别是: 1、上一根日线BAR的最高价。 2、上一根日线BAR的收盘价。 3、上一根日线BAR的最低价。

    这些数据非常好获取。

    var r = exchange.GetRecords(PERIOD_D1) // 获取K线数据
    var preBar = r[r.length - 2]           // 上一根日线BAR
    var preHigh = preBar.High              // 上一根日线BAR最高价
    var preClose = preBar.Close            // 上一根日线BAR收盘价
    var preLow = preBar.Low                // 上一根日线BAR最低价
    

    然后计算阻力价、支撑价。

    var pivot = (preHigh + preLow + preClose) / 3            // 中线
    var resistancePrice1 = 2 * pivot - preLow                // 阻力价1
    var resistancePrice2 = pivot + (preHigh - preLow)        // 阻力价2
    var resistancePrice3 = preHigh + 2 * (pivot - preLow)    // 阻力价3
    var strutPrice1 = 2 * pivot - preHigh                    // 支撑价1
    var strutPrice2 = pivot - (preHigh - preLow)             // 支撑价2
    var strutPrice3 = preLow - 2 * (preHigh - pivot)         // 支撑价3

  • 触发交易

    • 突破 在空仓条件下,如果盘中价格超过突破买入价,则采取趋势策略,即在该点位开仓做多。 在空仓条件下,如果盘中价格跌破突破卖出价,则采取趋势策略,即在该点位开仓做空。
    • 反转 持多单,当日内最高价超过观察卖出价后,盘中价格出现回落,且进一步跌破反转卖出价构成的支撑线时,采取反转策略,即在该点位反手做空。 持空单,当日内最低价低于观察买入价后,盘中价格出现反弹,且进一步超过反转买入价构成的阻力线时,采取反转策略,即在该点位反手做多。
    • 收盘 下午收盘平仓。

设计为多品种策略

我们采用和之前文库中的一篇文章「商品期货多品种均线策略」中一样的程序架构。把均线模型替换成R-Breaker模型。但是增加一些其它扩展,给每个品种增加图表显示,显示支撑线、阻力线。给每个品种增加一个交互按钮,可以在盘中手动平仓。

策略源码

策略参数很少,策略本身逻辑的参数一个也没有。

合约列表中的合约代码参数以英文逗号间隔,例如:rb2101,MA101,j2101,i2101,p2101,AP101。这样策略就针对这些合约品种操作。
