Same thing would apply to anything overbought. You would need the 15M RSI & 15M Stochastic (with the settings default....don't change anything) crossing down the 80 red line and 70 line on RSI. When this sort of thing occurs on High-time frames & especially the Weekly & Daily converging at the same down, you can ride for example currency pairs for days and days. It will work better on these big timeframes.
