Uncertainty in the forex market.
A trader who stalls out in a losing position does not put a stop with his exchange because of him accepting without a sorry excuse for an uncertainty the market will move toward the path he has anticipated, on the off chance that he had even the scarcest piece of uncertainty about the bearing of the market he would put a stop on his exchange to ensure his position, since he doesn't trust this when the market inevitably moves against him he neglects to understand his examination has been off base, and keeps holding the exchange with the desire that the market will eventually move back to support him and he will have been right from the start.
