This is true, traders always have prediction and that is binary traders which is rely on guessing the strategy. So, why they don't speculate since speculation is very useful to some traders aside from their analysis or tools that they used. Traders speculations were base on their decision and they have the right to speculate their own since trading is more based in prediction thing, so I think there's nothing wrong in speculating the market and follow your heart beat on you are going to predict.
