There are many indicators which can help us to determine the overbought and oversold area. The most common indicators to determine the overbought and oversold area is stochastic oscillator, but you can
also use Relative Strength Index, Momentum, Willams percentage, etc. But i found these indicator often give a wrong signal. to identify overbought or oversold price I use indicators RSI with the setting 20.50.80. or
it could be using the indicator StohasticOs. It is pretty easy to identify price with this indicator
