Statistically about 1700-1800 ETF/ETN, you know how to run a script. so it's easy to screen the 1700-1800.
You will get less than 400 ETF/ETN, active and could run 跑赢大市.
Last, I would suggest your script "dynamically" update the ETF/ETN tickers so that you don't miss any new one, even one day delay.作者: sjwi 时间: 2015-2-13 10:28
