yes, you are correct my friend. to find out overbougt / oversold, we can not use just one indicator. we need to confirm with other indicators. we can use MACD, RSI, and maybe we need to add fibonachi. possible to use it can help to make profits in trading.Dear you can use the these type of indicators to take a decision but please do not only realy on one indicator of you found that the same signal from 2 or more indicators then please only then take your decision. And try do some other analysis.
