Stochastic is an indicator, which can be called a classic solution for traders who trade on a variety of strategies. It can be used even with the basic settings and it will also help to determine the price trend of almost any asset. I have not tried how it works with indices, but it correlates very well with currencies and metals. Stochastic can be recommended to those who are just starting their way on Forex or in another direction of trading, because it is very easy to process and can be easily used for short positions and long-term, depending on the market situation.
