| 一,如何把“K线走完模式”的模型转换成“固定轮询模式”的模型
 以便把各个模型放在同一个框架内进行图表程序化交易
 
 举例:
 
 均线交叉模型(K线走完模型):
 
 runmode:0;
 
 ma5:=ma(c,5);
 
 ma20:=ma(c,20);
 
 entertime:=time>100000 and time<144500;
 
 if holding>0 and ma5<ma20 then sell(1,1,market);
 
 if holding<0 and ma5>ma20 then sellshort(1,1,market);
 
 if holding=0 and ma5>ma20 and entertime then buy(1,1,market);
 
 if holding=0 and ma5<ma20 and entertime then buyshort(1,1,market);
 
 if time>=150000 then begin
 
 sell(1,1,market);
 
 sellshort(1,1,market);
 
 end
 
 
 
 简单的改法,自然是把各个条件“过去化”,如:ma5 改为 ref(ma(c,5),1);但这种方法碰到大型的、复杂的模型时,容易出错
 
 可采用这种方法,把holding用全局变量cc替换,然后加入红色部分代码,红色部分代码要放在信号语句的前面:
 
 runmode:0;
 
 variable:cc=0;
 
 ma5:=ma(c,5);
 
 ma20:=ma(c,20);
 
 entertime:=time>100000 and time<144500;
 
 if holding>0 and cc<=0 then sell(1,1,limitr,o);
 
 if holding<0 and cc>=0 then sellshort(1,1,limitr,o);
 
 if holding=0 and cc>0 then buy(1,1,limitr,o);
 
 if holding=0 and cc<0 then buyshort(1,1,limitr,o);
 
 if cc>0 and ma5<ma20 then cc:=0;
 
 if cc<0 and ma5>ma20 then cc:=0;
 
 if cc=0 and ma5>ma20 and entertime then cc:=1;
 
 if cc=0 and ma5<ma20 and entertime then cc:=-1;
 
 if time>=150000 then begin
 
 cc:=0;
 
 end
 
 
 
 那么,如果是 K线走完模式和盘中模式并存,怎么做呢?也简单,就是在“开盘价下单语句”后面加入蓝色部分的“盘中下单语句”就行了
 
 如下:
 
 runmode:0;
 
 variable:zs=0,cc=0;
 
 ma5:=ma(c,5);
 
 ma20:=ma(c,20);
 
 entertime:=time>100000 and time<144500;
 
 if holding>0 and cc<=0 then sell(1,1,limitr,o);
 
 if holding<0 and cc>=0 then sellshort(1,1,limitr,o);
 
 if holding=0 and cc>0 then buy(1,1,limitr,o);
 
 if holding=0 and cc<0 then buyshort(1,1,limitr,o);
 
 if cc>0 and l<zs then begin
 
 sell(1,1,limitr,min(o,zs-0.6));
 
 cc:=0;
 
 end
 
 if cc<0 and h>zs then begin
 
 sellshort(1,1,limitr,max(o,zs+0.6));
 
 cc:=0;
 
 end
 
 if cc>0 and ma5<ma20 then cc:=0;
 
 if cc<0 and ma5>ma20 then cc:=0;
 
 if cc=0 and ma5>ma20 and entertime then begin
 
 cc:=1;
 
 zs:=c-10;
 
 end
 
 if cc=0 and ma5<ma20 and entertime then begin
 
 cc:=-1;
 
 zs:=c+10;
 
 end
 
 if time>=150000 then begin
 
 cc:=0;
 
 end
 
 
 二、移动止损的编写方法:
 还是以之前的模型为例,希望加入移动止损,即:开仓后的最高点回落10个点要盘中止损离场
 加入一个全局变量 hl,记录开多后的最高点,开空后的最低点:
 runmode:0;
 variable:zs=0,cc=0,hl=0;
 ma5:=ma(c,5);
 ma20:=ma(c,20);
 entertime:=time>100000 and time<144500;
 if holding>0 and cc<=0 then sell(1,1,limitr,o);
 if holding<0 and cc>=0 then sellshort(1,1,limitr,o);
 if holding=0 and cc>0 then buy(1,1,limitr,o);
 if holding=0 and cc<0 then buyshort(1,1,limitr,o);
 if cc>0 and l<zs then begin
 sell(1,1,limitr,min(o,zs-0.6));
 cc:=0;
 end
 if cc<0 and h>zs then begin
 sellshort(1,1,limitr,max(o,zs+0.6));
 cc:=0;
 end
 if cc>0 and ma5<ma20 then cc:=0;
 if cc<0 and ma5>ma20 then cc:=0;
 if cc=0 and ma5>ma20 and entertime then begin
 cc:=1;
 zs:=c-10;
 hl:=h;
 end
 if cc=0 and ma5<ma20 and entertime then begin
 cc:=-1;
 zs:=c+10;
 hl:=l;
 end
 if cc>0 and h>hl then begin//创新高后,上移hl
 hl:=h;
 zs:=hl-10;
 end
 if cc<0 and l<hl then begin//创新低后,下移hl
 hl:=l;
 zs:=hl+10;
 end
 if time>=150000 then begin
 cc:=0;
 end
 
 三、逐K线模式的模型,用免FEI版下单交易的方法
 runmode:0;
 variable:cc=0;
 ma5:=ma(c,5);
 ma20:=ma(c,20);
 entertime:=time>100000 and time<144500;
 exitlong:cc<>1,tfilter;
 exitshort:cc<>-1,tfilter;
 enterlong:ref(cc,1)<>1 and cc=1,tfilter;
 entershort:ref(cc,1)<>-1 and cc=-1,tfilter;
 if cc>0 and ma5<ma20 then cc:=0;
 if cc<0 and ma5>ma20 then cc:=0;
 if cc=0 and ma5>ma20 and entertime then cc:=1;
 if cc=0 and ma5<ma20 and entertime then cc:=-1;
 if time>=150000 then cc:=0;
 
 原理是,用全局变量cc记录仓位,然后根据仓位的变化情况来确定下单信号
 
 
 四、日内满仓反手的写法
 因为满仓的情况下,要等平仓单成交、保证金释放后,开仓下单才能成功。
 用系统自带的orderqueue在平仓单没有第一时间成交的情况下有一定的局限性,可用如下的方法:
 runmode:0;
 input:cw(3,1,10,1);
 variable:cc=0;
 ma5:=ma(c,5);
 ma20:=ma(c,20);
 entertime:=time>100000 and time<144500;
 if holding>0 and cc<=0 then sell(1,cw,limitr,o);
 if holding<0 and cc>=0 then sellshort(1,cw,limitr,o);
 //此方法撤单和追单时间要控制在出信号的K线时间以内
 if holding=0 and cc>0 and cw+tholding2>=cw then buy(1,cw,limitr,o);//平空成交后,"cw+tholding2>=cw "才会成立并开多
 if holding=0 and cc<0 and cw-tholding2>=cw then buyshort(1,cw,limitr,o);//平多成交后,"cw-tholding2>=cw "才会成立并开空
 if cc>0 and ma5<ma20 then cc:=0;
 if cc<0 and ma5>ma20 then cc:=0;
 if cc=0 and ma5>ma20 and entertime then cc:=1;
 if cc=0 and ma5<ma20 and entertime then cc:=-1;
 if time>=150000 then begin
 cc:=0;
 end
 
 五、自行计算最大回撤的方法,放到逐K线模式的模型最后面即可:
 
 zichan:asset,noaxis;
 if barpos=1 then begin
 MaxAsset:=zichan;
 Maxhc:=0; end
 if zichan>MaxAsset then MaxAsset:=zichan;
 if MaxAsset-zichan>Maxhc then Maxhc:=MaxAsset-zichan;
 最大回撤:Maxhc,linethick0;
 交易次数:totaltrade,linethick0;
 正确率:percentwin,l
