The reason for not doing that is simple laziness, why bother to learn how to trade when you can try to pay someone else to do it for you but once we use common sense we will realize that it is almost impossible for the OP to find anyone remotely good, revealing your strategy to anyone especially if it is profitable is a mistake and anyone that can make money in the market is not going to bother with this offer that seems to me like it will end up with someone getting scammed.
