Need help to get this Tradingview strategy from V2 to V5

I'm attempting to convert my script from v2 to v5 strategy and add Buy Sell Alerts for webhook trading on MT5 via Pineconnector. This script is working fine in v2, and I am able to see Buy/Sell Signals at screen, but also want alerts to pop up if any Buy/Sell signal appears to trigger Pineconnector.

Following is my script:

Am SUPER new to pinescript but need to be able to add in the strategy alerts available in V5 I started understanding the V4 differences to add in .int to input variables and.ta to technical indicators but got WAY too many other errors I don't understand. Thanks in advance to the smarter than I folks here!
