Create Indicator With Notification when break HL or LH

Hi Everyone,

I need and indicator with notifications. (Popup, Sound, Handphone, email)

Base on the valid image attached,

1) From uptrend, price goes down to create a HL than goes up again to create a new HH. Than price goes down again and break the previous HL price. the CS will need to close below the HL low and any Low between HL and CS that break the Price.

2) Price when back up to touch on HL CS close price

3) CS Close below HL CS close price

4) Notifications

Notification will be invalid if point 3, CS close above HL CS close price as photo attached

Thank you
