[Python源码] 十大经典日内策略之空中花园（附源码分享）
今天为大家介绍十大经典日内策略系列的第三个——空中花园。空中花园的策略思路非常简单粗暴，同样的确定今天的交易通道。但是通道的确定依据的仅为今天第一根bar信息：上轨=第一根bar的最高价；下轨=第一根bar的最低价。8 h7 x' X) g5 S+ ^6 z) s. o入场条件：和所有突破通道的策略一样，价格突破上轨做多，价格突破下轨做空。但是为了保证赢面，限制了今天开盘的状态，只在今天是高开或者低开的时候，才进行轨道变化，否则沿用的仍为上一次的通道。
出场条件：同样，反手出场。同时，收盘前，主动出场。
下为源代码：function kzhy(freq)%
targetList = traderGetTargetList();
%获取目标资产信息
HandleList = traderGetHandleList();
%获取账户句柄
global upline;
global dnline;
if isempty(upline)||isempty(dnline)
upline=zeros(length(targetList),1);%记录今天通道的上轨
dnline=zeros(length(targetList),1);%记录今天通道的下轨
end
for k=1:length(targetList);
%--------------------仓位、K线、当前bar的提取-----------------------------%
%获取当前仓位
=traderGetAccountPosition(HandleList(1),targetList(k).Market,targetList(k).Code);
%策略中每次取数据的长度
lags=40;
dlags=31;
barnum=traderGetCurrentBar(targetList(k).Market,targetList(k).Code);
%数据长度限制
if(barnum<lags)
continue;
end
%获取K线数据
= traderGetKData(targetList(k).Market,targetList(k).Code,'min',freq, 0-lags, 0,false,'FWard');
