MA's are a simple and an easy way to find the trend on anytime frame.
A lot of people use the 200 MA to define trend but I've always preferred EMA's.

2 .Below the cloud the assumption is
3 . Change in color is confirmation of a trend change
Note that all MA's lag so use with confluence of other technical indicators.
