If price pierced upper or lower Bollinger Bands, RSI is overbought/oversold and moves back to 50 you’ll get a signal.
Of course some false too, but as always MM and tight stop loss is the key. Recommended time-frame is M5. Added some objects that you are able to prepare for a signal.
RSI object gets orange when overbought/oversold and changes to green or red when returns towards 50. Bollinger Band object gets red or green when Bands were pierced.
If there is a higher high/lower low after a sell/buy signal and there is no new signal, RSI should show a divergence and you know what that means.
