I'm investigating a situation where the chance for gain or loss is the same, but the amount gained is greater than the amount that is lost. For example, the gain would be about 30% of the trade amount, and the loss would be 23% of the trade amount. While there is slightly more to it than that, that is the core of it -- random/even chance for hitting the gain or the loss the way the trade is structured, and approximately the percentages indicated. Please note either the gain or loss will be reached.
If one has amount A to invest, what considerations need to be taken into account to make a situation like this profitable, or is it not possible for it to be profitable (e.g. due to many successive losses)?
