Convert pinescript (Tradingview) alert/strategy script to MT4 EA

Hi, I have an indicator/strategy from tradingview (pinescript) that I would like to convert into the form of a MT4 EA.

With the EA, I would like to be able to customize the following inputs:

-lot size (% vs fixed lots)

-trailing stop setting

-time frame

I would also like the EA to have a feature where it sends an email or mt4 notification when it opens/closes a trade. The EA must also allow the user to close trades manually (i.e. not place the same trade after closing it)

Thanks!
