主题：跟踪止损可以么

IF c-ENTERPRICE>=30*pointvalue then markprice:=enterprice+30*pointvalue;//记录盈利30点

//止盈
 

IF HOLDING＞0 AND c-ENTERPRICE<=-30*pointvalue or (c<markprice and markprice=enterprice+30*pointvalue) THEN

begin

SELL(1,0,LIMITR,close); //30点止损+30点保护

markprice:=0;//30点止盈保护清0

end

IF HOLDING<0 THEN BUY(1,0,LIMITR,LOW); //这样真的好吗，最低点开仓？
