How To Do Business With Advance-Decline Line
In general, if the market is trading upward and the advance-decline line is sliding downwards (deviation). Then it indicates that a current trend is losing its strength and can be reversed soon. If the market is moving upwards and similarly there is an advance-decline line. Then the situation is stable and the current trend is strong.
The deviation that can be seen between the price and the indicator line is only a warning of possible changes to settle. A deviation factor for the ADL indicator can last longer. So the ADL indicator cannot be used as a time indicator.
