Philosophy
This study attempts to redefine divergence by allowing flexibility in the established mantras associated with the subject. The traditional interpretation is that if price is going in one direction and the momentum indicator in the opposite direction, divergence is occurring and suggests that the trend is ending. The reality is of this basic theory is that all but the strongest trends will diverge and often give false exit signals to trend following trades and false reversal signals against the trend.
The increased flexibility derives from the ability to not only look for divergence on the indicator itself, but replace this with a moving average of the indicator in or order to smooth out and reduce the number of turning points. The traditional mantra looks at absolute highs and lows of price to define divergence but this study enables the trader to select what price should be used to qualify. This means if for example the relationship of the close instead of high and lows is used, it reveals the ability to quantify divergence in sideways markets in order to produce and early warning to a break out and new trend. This is referenced as divergence as a continuation. This use of different momentum indicators and variables of them to create divergence enables the trader to define how aggressive or conservative they wish there signals to be.
Interpretation
Each momentum indicator used for divergence has different characteristics and therefore different trading opportunities. Whilst the Adx is a good indicator of trend it has one inherent flaw. This involves sharp reversals from the previous trend. The Adx will not pick this change and the indicator will fall in value even though the new trend is strong. This means that the secondary trend will not produce any worthwhile signals. Its second important characteristic is the relative slowness in directional volatility in relationship to many other momentum indicators. This means that divergence can take far longer to be evident. The default settings interpret divergence by isolating a change in direction of the Adx or the moving average of the Adx and at that moment recording the value of the study itself and the default value of the bar. Divergence is qualified when they move in opposite directions on a certain number of consecutive occasions. A positive divergence is revealed by a red line recording a value of one and a blue line a negative signal. This highlights how the raw code is primarily of use as an exit tool to existing trend following trades. However, the building of code within the formula tool box enables traders to increase the accuracy of divergence qualification by focusing on the absolute value of the Studies or |bar values and creating more exact threshold parameters.
AdxDiv Parameters
|
Name |
Default |
Definition |
|
N |
1 |
the number of divergence patterns that are needed to produce a signal. Most only need 1 and will not produce signals if increased. |
|
ADXDiv Period |
5 |
Qualifies a propriety area within which signals do not have to be symmetrical. |
|
MA Period |
1 |
This second period refers to the variable of the moving average. Setting it to a number beyond 1 means that the average is being used as the divergence tool and not the original indicator. |
|
ADX Period |
21 |
The Adx variable to be used in the divergence calculation providing the Period of the Ma is set at 1. |
|
Lookback |
25 |
Qualifies the lookback period for when divergence can occur within. Increasing the number will normally increase the number of divergence signals and for slow moving indicators should be raised from the default. |
|
MA Type |
MA Types: •Simple •Smoothed •Exponential •Weighted •Centered •Median •Trix •Exponential Hull |
Qualifies the type of moving average to be used. |
|
AdxDivDn Price |
High |
Qualifies the relationship within the change in direction of the indicator and the subsequent bar value to be recorded at that point. |
|
AdxDivUp Price |
Low |
Qualifies the relationship within the change in direction of the indicator and the subsequent bar value to be recorded at that point. |
