Simple pinescript for tradingview with alert

Simple pinescript alert that can be backtested. I need entry points mapped out at candle start at 2 different times and a high and low line from a specific time each day, these lines will be visible and go until market close. The script will simply create an alert for a buy order if second green candle forms above the zone and if the second red candle forms below the zone. Will need to be able to backtest this and will need to be able to adjust tp and sl.
