主题：老师好，请教一个问题

开仓:buy(holding=0 and 开仓条件，1，market);//开仓部分自行完善处理下

VARIABLE:mark:=0;//限制加仓一次

input:M(14,1,300,30);
TR1 : MAX(MAX((HIGH-LOW),ABS(REF(CLOSE,1)-HIGH)),ABS(REF(CLOSE,1)-LOW));
ATR : MA(TR1,m);//系统自带的atr指标的代码

ma5:ma(c,5);
ma10:ma(c,10);
buycond:cross(ma5,ma10) and holding=0;//开仓条件
sellcond:cross(ma10,ma5);

if buycond then buy(holding=0,1,market);//开仓

ct:atr/ref(atr,BARSLAST(buycond));//上次开仓条件成立时的art值和当前atr比值

jccond:ct>1.5 and ct<2.5 and holding>0 and mark=0;//加仓条件

zscond:ct<0.75 and holding>0;//止损条件

zycond:ct>4 and holding>0;//止盈条件

if zscond then
begin
sell(holding>0,holding,market);//止损
mark:=0;
end

if jccond then
begin
buy(holding>0,1,market);//加仓
mark:=1;
end

if zycond then
begin
sell(holding>0,holding,market);//止盈
mark:=0;
end

if sellcond then

begin

sell(holding>0,holding,market);//止盈
mark:=0;

end
