Rotational system with one fix short position

Hi. I've already done a search here in the forum and in google but anything was useful. Mi idea is to choose some shares to go long in a sector (oil for example) covering this part shorting a ETF from the same sector (like USO).
So my thoughts are focused in a rotational system setting the USO score to -9999999 but I don't know if it's possible and how to do it.
Any idea or similar previous question already solved?
Thanks in advance
