回测K线质量历史 没有100% 说明啥问题啊？

跨度到2000年 质量历史只有6%  是不是压根就不能用啊，怎样才能获取高质量的数据啊

按照上述方法下载新的数据 回测时 还是提示质量只有6% 从2000年开始的欧元5分钟数据

According to the above method, when downloading the new data back-testing, it still prompts that the quality is only 6%. Euro 5-minute data since 2000

It depends on the broker.
Because all the data, all the charts, names of the symbols, symbols specifications, time on the price of the chart - all of them are related to the broker.
