Dear Mangup,
Linkon7 was saying that divergence signal can be used better as a EXIT signal than for entry.
A divergence denotes decrease in momentum. Momentum comming down does not mean thats momentum in the trend is over, It can pick up again any point of time. By leaving accelarator of the vehicle one can slow down the speed( momentum) but cant stop the vehicle immediately from motion unless a brake is used. It travels in the direction to some distance till the momentum is completely exhausted.The same way a divergence in RSi or any other indicator with price does not mean that the trend is over, it only indicates the momentum in the direction has come down but still the price can continue in the trend for some time and that is when we see double and triple divergences.
And we never know if those momentum triggers are really exhausted.
Because i never know why ones slowed down the accelarator. may be you dont have enough fuel to go ahead or may be you wan you see a charming lady passing by. If its the second cause, you will speed up the next moment.
I can only confirm if you took a u turn. And may be thats the reason we see in every article that "Divergence has to be confirmed".
Like linkon7 sir said when divergence coupled with any other factor like low volumes will increase the odds. but trading divergence as only factor is not at all a good idea. In trending markets you can see most of the moves comming after good divergence signals. Divergences cant beat the trend. A valid divergence may only halt the movement for sometime. This applies for any time frame.
