Metatrader 4 Indicator Alert

I need a bespoke indicator for Metatrader 4 to provide buy and sell alerts depending on 2 further indicators. The alert should: 1. Print a red down arrow above price for a sell signal 2. Print a blue up arrow below price for a buy signal 3. Show past signals for backtesting 4. Have a pop up alert with sound when a new signal is generated 5. Only provide a signal at the close of a bar on the 5 minute chart
