Adding a HL and LH alert to an existing indicator

I have an existing MTF ZigZag Fibo indicator that I want to add an alert to. I think it would be an easy project

Currently, it will with certain settings, draw the HH/HL/LH/LL text for me.

What I need.

I want to set an alert to pop up based on the setting below if the latest HL is higher than the previous LL/HL and/or if the latest LH is lower than the previous HH/LH.

Just to make it clear, only alert if a high was lower than a previous high or a low was higher than a previous low. Nothing else.

It is defined as a HL alert when the candle following the HL/LL candle closes above the high if the candle with the flag and vice versa. So you must wait for the HH/HL/LH/LL flag to form, then then the next candle that close above or below the high or low of that candle.

A separate alert that will control only the settings for HL and LH alerts similar to this example

The alert setting right at the bottom must remain as is and still work
