I will be using short sentences so that it is easy to grasp and understand.
For a detailed overview, please visit the sources attached after the explanation.
DMS stands for System
It measures the direction of trend in the market
+DMS (Green Line) measures positive trend (uptrend)
-DMS (Red Line) measures negative trend (downtrend)
ADX stands for
It measures the strength of the trend in the market, regardless of direction and confirms price movement (Black line)
It is measured from 0 to 100
It can also confirm if the market conditions are ranging or trending.
It is a lagging indicator i.e. it is used to confirm the direction of price movement and cannot be used as a trigger.
ADX/DMS indicator consists of 3 lines
Green line which is +DMS, Red line which is -DMS and Black line which is the line
is derived from smoothened averages (14 period) of difference between +DMS and -DMS.
Directional movement is calculated by
Comparing the difference between 2 consecutive lows… with the difference between their respective highs.
+DMS and -DMS are derived from smoothened average of these differences.
ADX hacks that you can use to understand signals and charts better -
When is below 20 it is a ranging market
When moves above 30 it indicates a strong trend. The duration of the trend is based on duration of the range before it.
sloping means trending market conditions.
with a flat slope means ranging market conditions.
When +DMS crosses -DMS, with over 30 and going up, it is a buy signal confirmation.
When -DMS crosses +DMS, and is above 30 and going up, it is a sell signal confirmation.
