I wanted to give you an example of, when a person has superficial knowledge and little experience, but rushing in a bunch of terms, he think, what can give the impression of a knowledgeable person.
He phrases the question this way:
"такс, simplifying the task. Average size of a profitable trade 846$, the probability of a profitable trade – 54%. What is the maximum loss allowed, so that the law of large numbers in the long run would allow the total result to be at least zero? "
That , what is mentioned in the question , как "вероятность прибыльного трейда", actually there % profitable trades in the past.
Who will tell me, what is this question amateurishlym?
