Well, IMHO You can apply the very same AFL command to the Close (or Avg, or whatever you want) instead of MA. Anyway I feel the issue behind is how to define the periods on which compute the slope. I means, if you do some trials you will find completely different results depending on the value of “periods” you set. But this is Your decision, I suppose based mainly on your trading time-frame, and may be the TS you have in mind.
