想用llt模型做金字塔的交易，这里是别的语言的，希望能改成金字塔的谢谢

LLT择时模型，低延迟趋势线，。利用最近20个LLT指标数值，大部分LLT呈现上涨（斜率为正），做多；大部分下跌（斜率为负），做空；反向出场。

策略代码：

function LLTg(freq)

targetList = traderGetTargetList();

HandleList = traderGetHandleList();

for i=1:length(targetList)

marketposition=traderGetAccountPosition(HandleList(1),targetList(i).Market,targetList(i).Code);

barnum=traderGetCurrentBar(targetList(i).Market,targetList(i).Code);

len=60;

dlen=60;

[time,open,high,low,close,volume,turnover,openinterest] = traderGetKData(targetList(i).Market,targetList(i).Code,'min',freq, 0-len, 0,false,'FWard');

[Dtime,Dopen,Dhigh,Dlow,Dclose,Dvolume,Dturnover,Dopeninterest] = traderGetKData(targetList(i).Market,targetList(i).Code,'day',1, 0-dlen, 0,false,'FWard');

if length(close)<len+1||length(Dclose)<dlen+1

continue;

end

a=2/(1+30);%d=30

%计算操作指标

lltv=LLT(close,a);

k=lltv(2:end)>lltv(1:end-1);

con1=sum(k(end-20:end))>=fix(0.9*21)&&k(end)==1;%斜率为正，上升阶段

con2=sum(k(end-20:end))>=fix(0.1*21)&&k(end)==0; %斜率为负，下降阶段

shareNum=1;

if marketposition==0

if con1

% traderBuy(HandleList(1),targetList(i).Market,targetList(i).Code,shareNum,0,'market','buy');%开多单

orderID = traderBuy(HandleList(1),targetList(i).Market,targetList(i).Code,shareNum,0,'market','1');

elseif con2

orderID = traderSellShort(HandleList(1),targetList(i).Market,targetList(i).Code,shareNum,0,'market','1');

end

if marketposition>0 &&con2

order= traderPositionTo(HandleList(1),targetList(i).Market,targetList(i).Code,0,0,'market','sell');%平多单

end

if marketposition<0 &&con1

traderBuyToCover(HandleList(1),targetList(i).Market,targetList(i).Code,shareNum,0,'market','buytocover');%平空单

end

function LLTv=LLT(price,a)

LLTv=zeros(length(price),1);

LLTv(1:2)=price(1:2);

for i=3:length(price)

LLTv(i)=(a-a^2/4)*price(i)+(a^2/2)*price(i-1)-(a-3*a^2/4)*price(i-2)+2*(1-a)*LLTv(i-1)-(1-a)^2*LLTv(i-2);

end
