CandlesticksPREVIOUS HIGHS AND LOWS INDICATOR MODIFICATION

1
Hey guys hope everyone is doing well in Q4.
I got this simple mt4 indicator for previous highs and lows. which sends terminal alerts and phone notifications. The problem is iteration since it will repeat the same notification as many times when prices cross these levels. e.g PDH, PWH or PMH.
If possible, can someone please add user interval for terminal alerts/phone notifications settings.
Example:
USERINTERVAL_TIME = TRUE /FALSE
USERINTERVAL = 60MIN
This way one can set the interval of which the same level alerts to avoid lots of notification on the same level of up to 10 times on the same candle before it closes.

Add Bid price and Date Time on phone notifications.
Add Session Highs and Lows (Asia, London, New York)

It's really a good indicator for those traders who trade liquidity and time-based approach. Attached is the Mq4 file.
I will appreciate the help thanks.
