How do I write a script to buy the best performing mutual fund or ETF of a universe that I create?  I have tried to use the click and drag feature of Fidelity's WealthLab but it appears I cannot.  Or if someone can direct me to a similar strategy that I can look at to figure out how to write it.  My goal is to buy the top 3 funds/ETF's of the universe I intend to create and hold for 1 month and resort/trade etc.
