Trend Calculation - Returns symbol

Hi All
I have attached example

What I'm looking to achieve is in Cell C5 I want to see a Green arrow pointing up if the trend for the last 12 months is showing improvement, Yellow sideways for Static performance and Red down arrow is performance is getting worse

Is there a way to achieve this by only using a formula, as I don't wish to use VBA or Macro's

If needed I can added additional data to the sheet

Thanks In advanceTrend Test.JPG

It would help if you attached a sample Excel workbook, as it is difficult to read that picture.

Sorry couldnt work out how to do that - See attached

Could you please advise what the calculation should be to go in each cell

In the attached I've included a graph which shows the trend over the 12 month period I:e Feb 2017 back to March 2016
The graph represents what I'm trying to achieve however Instead of having a graph I want to just use the arrow in cell C5 to show the trend Up, Down , Sideways

Hope this helps
