Formula sequence

Is there a way to control the sequence in which formulas in various cells in a spreadsheet are performed, without using macros?

I am analysing data imported live with various conditional formulas and issuing instructions based on the results, but to avoid conflicts the formulas have to be calculated sequentially and in a specific order
.
I would be most grateful for any suggestions.

Although not very clean, you could have a cell which represents your calculation step - let's name it 'Stepper'.

Then in the formulae you need to calculate first, you would utilize:
=if(Stepper>=1,<your formula here>,"")

The second set of formulae would be:
=if(Stepper>=2,<your formula here>,"")

And so on.

You would then manually increment the Stepper cell to ensure calculations are done in sequence.
