MT4 Perpetual Price Indicator

I want an indicator that sends notifications in perpetuity whenever the determined price levels are touched/crossed from either direction

Opening the terminal should be unnecessary to continue receiving notifications as prices are crossed/re-crossed from either direction

On the tick when the price of a symbol on a chart is touched/crossed, the indicator should send a notification to the terminal  ( e.g. “USDJPY 110.123”)

The notifications should have a 60 second timeout and no maximums

Up to four such prices should be allowed to be set per chart

Thank you!
