Knowing if a trend is still valid or is beginning to fail

in the above image you can see, that when all moving averages do not cross or overlap one another, this indicates a strong trend/price sentiment in this direction, even after a major pullback, you'll notice the moving averages still dont cross or overlap.

also on the chart image ive touched upon the very popular 1, 2, 3 trading pattern and highlighted that there's a not so obvious 4 reset wave before the 1, 2, 3 pattern starts again, the trick is check to see if the phase 4 wave causes any of the moving averages to cross/overlap before setting up your 1, 2, 3 move! because if they have crossed or one of them is overlapping the other, this signals the trend is weakening and the market may be looking at beginning a range or and new trend in the opposite direction.
