In a trend there are always two type of "participants" First of all, there are innovators and then motivators :) Numbers will not help you (it's not about probability at all :) ), they reflect patterns in human psychology. If you take the whole number of market participants (speculators) involved in a trend, you will probably see significant growth as trend emerges. Those numbers show approximate percentage of participation.
Update on how they use to trap and we should wait for complete close.
So, idea behind this chart is that we should wait and see the behavior, why they are offering low price to enter again, and allowing a pullback entry at cheaper prices and the reason I have mentioned Innovators start selling the price from top, and motivators try to trap you to join the trend once again,
But the result is often different as in this case and I am still looking for much powerful decline in the pair.
