I am curious to know which magick to perform if some one wants to maintain, to keep his/her economical status, not rich, but not poor, but a simple acceptable medium one.
I think a simple protection ritual for your business/job would be a nice idea, I usually practice the ritual “protect your buisness” from the “Greater words of power”, it protects your business from bankruptcy, theft, bad employees, bad debtors, legal problems and cash flow difficulties. 
What rituals do you do to keep your financial status?
Try any demon that deals with wealth
currently none.
I would buy a copy of Jason Miller’s book Financial Magick, and perform the Invocation of Jupiter within it daily.
What do you plan on doing?
