The Average Directional Index
, or ADX, was developed by J. Welles Wilder to determine trend forces , whether the trend in forex trading will grow on or will gradually lose its positions. This indicator lets analyze the market tendencies and make trading decisions in the market of forex trading.
In fact,
ADX relates to the class of oscillators, which changes positions in a range from 0 up to 100. Though the indicator's fluctuations are in a range from 0 and up to 100, it seldom goes over a point of 60. If the value is lower than 20 demonstrates a weak trend, if the value is over 40 shows a strong trend. Position above 40 indicates both strong descending, and a strong ascending trend.
Sometimes
ADX helps to determine potential changes in the market of forex trading. Once the indicator grows over 20 points from below upwards, maybe, it's the sign of the trend's change and its further development. When the indicator shows value less than 40, falling from higher level, it means that the trend has lost its positions.

ADX
descends from two other indicators which were also developed by Wilder. The first one is called Positive Directional Indicator, or just "+DI", the second one is -Negative Directional Indicator, or "-DI". On the chosen time interval +DI - shows force of upwards movements, and -DI on the contrary shows force of downwards movements for the certain period. ADX indicates the trend's force and coalesces +DI and -DI smoothing data with changing average.
The use: Usually buy and sell signals act on crossings +DI/-DI as following: a sale signal occurs, when -DI crosses +DI from top, and the buy signal occurs, when +DI crosses -DI from below.
It's crucial
for the trader in forex trading to notice a trend at an early stage of development to gain maximum benefit from his deals. And ADX helps him in that. For that purpose it's quite important to watch currency pairs in the market of forex trading where ADX crosses 20 from below upwards. Correspondingly decreasing ADX less than 40 points indicates that the ongoing trend is weakened and the trading range starts. So ADX demonstrates presence or absence of a trend, and for determining a direction of an input and input points you should better use other kinds of indicators.
In the falling market,
-DI grows, and +DI goes down, and the market moving upwards +DI rises, and-DI goes down. If the trend is strong and quick, the corresponding movement DI will be as strong and quick. If +DI and-DI are set against each other, in the market there was a balance and there is a movement sideways. The market tendency of forex trading changes at crossing of DI lines; if +DI has fallen below -DI, it means sellers became more active and the market starts moving downwards, if +DI crosses -DI upwards, in the market there is a bull situation with the majority of buyers. So crossing of lines DI is a sign to sell or buy.
