如果数据库有数据则不再 请求jqdata是吗
发现有一个机器的vnpy有订阅了IF2001.CFEEX
但没有开启订模块的窗口,是不是要vnpy 启用就会自动录下
此前添加的要录制的合约,即使没有开启录制窗口
sp 之类的价差合约没法订阅
在策略中能直接交易这些 合约吗,会有tick推送吗
回测那有个数据下载框,但只能选择k线周期的,
有下载tick数据入口吗
当价格变化太快时,一根k线的价格变化分别满足两个不同价格的平仓条件时
,回测引擎是不是把其中一个平当成了开, 日志显示一个开仓,平仓有两个

在回测计算盈亏时,我们设置的滑点和手续费
,一个单由开仓到平仓
是只减掉一边的滑点和手续费
还是开平两边都减掉了滑点和手续费
统计开仓后的最高低最低价
(
intra_trade_hight
intra_trade_low
)
源码的写法是不是有误
统计范围包括了成交前那一根k线了
