This in itself already results in a price plunge.
Now there are OTHER people who are not using the signal service. But they see a sudden drop in price and they wonder what happens -- so some might decide to quickly sell in order to catch the wave. Then a while later, the more cautious ones decide that it is indeed safe to follow the trend to go short. So they sell as well. By this time, this group of people may already be too late -- BUT note that for those subscribed to the signal service, they might have already reached their planned profit target.
Thus I say, this is a self-fulfilling prophecy. And this will only come to pass when there are enough people participating. And of course, we are talking about "enough" of their combined financial muscle.

yes yes at that point exactly when trend gets strong and more more participants enter. but the question is the system we use , at which point of the trend it gives signal.
tha main thing was , is the efficency of a system declines when the users of that system increse?
well i dont know yet ! do you have any other suggestions or idea or whatever?
