Do we have available a moving average indicator that would change colour when the average changes direction.......

and , further to that, is it possible to create an indicator that would be able to use, say three or four moving averages and then create an alert when two or three of them are going the same way.....?

I am new to writing code for Metatrader so I have to ask a few questions before I can develop some ideas.......

Thanks for your help
