一.封装类Kline
1.实现
(如果需要用多个同一类型的指标，建议接口传入数组参数)
(如果同一类型的指标只用到一次，可以写在接口里面)

#include <wz\Kline.mqh>
Kline kl(Symbol(),0);
//+------------------------------------------------------------------+
//| |
//+------------------------------------------------------------------+
void OnStart()
{
//1.获取ask
//1.1直接获取
double ask=SymbolInfoDouble(Symbol(),SYMBOL_ASK);
//1.2 类获取
ask=kl.getAsk();
//2. 获取开盘价
//2.1直接获取
double open[];
ArraySetAsSeries(open,true);
CopyOpen(Symbol(),0,0,10,open);
//2.2类获取
kl.getOpen(10,Symbol(),0);
double open0=kl.open[0];
//3.类获取时间
kl.getTime(5);
datetime time0=kl.time[0];
//4.获取均线指标
int ma_h=iMA(Symbol(),0,12,0,MODE_SMA,PRICE_CLOSE);
double ma[];
ArraySetAsSeries(ma,true);
CopyBuffer(ma_h,0,0,10,ma);
double ma0=ma[1];
//4.1用类获取均线(如果需要用多个同一类型的指标，建议接口传入数组参数)
//12日均线
double ma12[];
kl.MA(ma12,10,Symbol(),0,12,0,MODE_SMA,PRICE_CLOSE);
double ma12_1=ma12[1];
//20日均线
double ma20[];
kl.MA(ma20,10,Symbol(),0,20,0,MODE_SMA,PRICE_CLOSE);
double ma20_1=ma20[1];
//5.获取ADX指标 (如果同一类型的指标只用到一次，可以写在接口里面)
kl.ADX(10,Symbol(),0,14);
double adx0_1=kl.adx0[1];
double adx1_1=kl.adx1[1];
double adx2_1=kl.adx2[1];
//6.自定义指标如何获取
int cus_h=iCustom(Symbol(),0,"BB",20,0,2);
double cus0[];
double cus1[];
double cus2[];
ArraySetAsSeries(cus0,true);
ArraySetAsSeries(cus1,true);
ArraySetAsSeries(cus2,true);
CopyBuffer(cus_h,0,0,10,cus0);
CopyBuffer(cus_h,1,0,10,cus1);
CopyBuffer(cus_h,2,0,10,cus2);
double cus0_1=cus0[1];
double cus1_1=cus1[1];
double cus2_1=cus2[1];
int a=1;
}
