Are you sure that there is a strategy that can bring money in trading or gambling on a permanent basis? I don't think there is such a strategy. Gambling and trading are high-risk activities in which the result depends not only on knowledge, skills and experience, but also on luck. Therefore, even if your strategy works today, tomorrow it can bring you such losses that you have never even thought about.
Trading strategy work most of the time whereas except sports betting or poker strategies donot work with luck gambling. I haven't seen anyone being able to get through with strategies as often as gambling. Whereas with trading as in day trading is not that easy for anyone. Day trading does provide a constant flow of daily income but you would need to be a pro in order to become a day trader.
