calCCIDatas method

dynamic calCCIDatas(dynamic high, dynamic low, dynamic close, dynamic p, dynamic a, dynamic b,)

计算CCI指标 @param close:Array 收盘点 @param high:Array 最高点 @param low:Array 最低点 @param p 回溯周期 (2 <= p <= 100) 默认传值 14， p之前的值是- @param a 上线 默认传值100 @param b 下线 默认传值-100

Implementation

  var size = high.length;
  var i = 0;
  var typ = [];
  for (i = 0; i < size; i++) {
    typ.add((high[i] + low[i] + close[i]) / 3);
  }
  var typ_avedev = AVEDEV(typ, p);
  var typ_ma = MA(typ, p);
  var cci = [];
  var ccisx = [];
  var ccixx = [];
  for (i = 0; i < size; i++) {
    if (i >= p - 1) {
      cci.add((typ[i] - typ_ma[i]) / (0.015 * typ_avedev[i]));
      ccisx.add(a);
      ccixx.add(b);
    } else {
      cci.add("-");

    }
  }
