Part VII. Average Directional Move Index – ADX

 Average Directional Move Index – ADX - Forex School

Commander in Pips:
 There are a lot of different indicators were invented during the most recent 20 years, and of course we can’t discuss all of them. So, I think, that we should finish discussion of particular indicators with this one – Average Directional Move Index, better known as ADX. This indicator also consists of a single line, and the major purpose of this indicator is the estimation of different phases of a trend. So it’s used for work with trend. The specific of ADX is that it does not show direction of trend, but only its strength. ADX is always positive and changes in 0-100 range. At the same time, this indicator rarely move above 50-60 level.

Pipruit: This is something new…

Commander in Pips: Yes. So, it was also created by W. Wilder and has some similar procedure in its math. But I know that you’ve tired from math already, so we will skip that during the current discussion. Anyway, you will want to study it later – you will easily find ADX formula in the net. It’s a bit complicated – almost as complex as the RSI one.

Pipruit: Thanks Commander, I owe you one.​

Commander in Pips: You’re welcome. So, let’s shift directly to application of ADX:

Chart #1 | GBP/USD Weekly and ADX (10)
GBP/USD Weekly and ADX - Forex School
ADX has only single tuning parameter – the number of periods, prices of which will be used for ADX calculation. The greater this period the more lazy and smooth the ADX line and the more rarely it will show significant moves. Here on the chart we have a 10-period ADX.

In general there are 4 signals that created by ADX Indicator:

1. When ADX stands in 20-25 range, then there is no significant trend on the market. Usually it happens when market volatility is shallow and market shows sideways move or stays in the range. On our chart you can see, that in beginning of 2008 and at the end of 2009 the market stands in range, so there was not a significant trend in this period.

2. When ADX rises above 25 and shows some acceleration towards the 40-50 area, then it points to a trend acceleration and its growing power.

3. As a derivative from the previous point, the jump of ADX by more than 3 points in two side-by-side trading sessions is an early warning that a trend has appeared. This property is very useful and popular amongst traders that use ranging strategies. For instance, if ADX has jumped for 3 points – then the possibility exists that market is turning to trend action and it’s time to exit. This is like a filter to understand whether the market in ranging price action or trending;

4. When ADX starts to decrease down from the 40-50 area it points that the power of trend is becoming weaker, and it starts to exhaust. This is an early caution, that possibly it’s time for gradual exit if you still hold your position with the trend.

All these scenarios you can see on Chart #1. Pay attention, as we’ve said that ADX does not show direction of the trend, it does not give you “Buy” or “Sell” signals. It’s just tells you how strong is the trend, whatever direction it is.

ADX signals are better to use as a confirmation of some possible breakouts. If, for instance, market has shown downward break and ADX jumps at least for 3 points, and after couple of days moves above 25 – then it confirms that possibly a new bear trend has appeared. Then, you may use the nearest retracement to Fib resistance for entering a trade.

Because of the fact that ADX does not tell you whether buy or sell, it’s obvious that you should use it with other indicators. And, finally, according to last 4th point – it could give you early notification, when it starts to decrease below 40, that possibly, it is time to close your position.

Pipruit: Hm, interesting indicator. Possibly I will use it.​

Commander in Pips: Yes, it could be useful. Of course you will have to experiment with them first, to study how to use it, and to find appropriate tuning parameters.

The standard ADX with the MT4 platform includes the DI+ and DI-, this can be useful as when the DI+ crosses above the DI- it indicates a bullish trend and vice versa

The ADX in my mt4 chart has about 3 lines. Get confused most time.
Do any one has the type Sive is using here that has only one line?
I sincerely appreciate for the help.
