What is Trend Symphony?
Trend Symphony is an MT4 indicator that draws short, middle, and large moving averages and shows candidate-turning arrows from their colour changes and crosses. Rising lines are green while falling or flat lines are yellow, so the displayed line positions and colours show direction and momentum.
How to use Trend Symphony
Read the order, colour changes, and arrow positions of the short, middle, and large moving averages. Compare it with whether all three line directions agree. An arrow appears when the short and middle lines cross while the three directions agree.
