Needa a simple MT4 indicator

Hi programmer, I need an RSI indicator with able to give me notification when the RSI is gone into my monitoring area. I have 2 level to monitor, one is for normal overbought and normal oversold; another is for deep overbought and deep oversold.

When the RSI is gone into normal overbought or normal oversold level, give me a notification.

When the RSI is gone into deep overbought or deep oversold level, give me a notification every candle if it still remains at deep overbought or deep oversold level.
