源码解析：

输出INPUT:周期
 输出INPUT:LENGTH(20,5,40,5)
输出INPUT:TRAILINGSTOP(3,1,6,1)
输出VARIABLE:STOPLINE=0
 TOPBAND赋值:昨日周期日内最高价的最高值+MINDIFF
 BOTBAND赋值:昨日20日内最低价的最低值-MINDIFF
 ATR赋值:昨日真实波幅的LENGTH日简单移动平均
 赋值:TRIMPRICE(TRAILINGSTOP*ATR)
逻辑判断 HOLDING=0 THEN BEGIN 逻辑判断 BARPOS>周期 AND 最高价>=TOPBAND THEN  BUY(1,100%,LIMITR,收盘价)
STOPLINE赋值:最高价-TRAILINGSTOPNUM
   逻辑判断 ENTERBARS>=2 AND 最低价<=STOPLINE THEN BEGIN  SELL(1,HOLDING,LIMITR,收盘价)
STOPLINE赋值:0
  END ENDPARTLINE(HOLDING>0 AND ENTERBARS>=2,STOPLINE,画黄色,1)
输出盈亏:ASSET,NOAXIS,画洋红色
 输出      收益:(ASSET-500000)/500000,线宽为0
输出次数:TOTALTRADE,线宽为0
输出胜率:PERCENTWIN,线宽为0
输出连亏:MAXSEQLOSS,线宽为0
输出连赢:MAXSEQWIN,线宽为0
