Translate indicator from a simple Pine script to MT4 + EA

Hello, I have an indicator written using Pine Script editor for the TradingView website, from which I'd like to have 2 outputs:

1. a parallel version in MQL4 so i can use it on MT4 (or if not possible in MQL5 for MT5);

2. an EA which opens and closes positions (buy and sell) based on the indications given by the indicator aforementioned.

The Pine script is very easy, 16 lines of code in total.

In the EA I'd like to be able to customize the following values:

A. tick interval (30m, 1h, 4h, ..)

B. lot size

C. symbol/pair currency

D. stop loss

E. few others internal variables

Plus, in the EA I'd like to have the following features:

F. if, when attached to the graph, the conditions are already met then it doesn't have to open a position but wait until the next one

G. send email both when it opens and closes a position

H. ability to close the position manually, when this happens the EA has to understand the position has been closed manually and doesn't have to open again a new position (even if the conditions are still met) for a set amount of time (amount of time which I'd like to be able to customize) or until the conditions change. If I'll close manually tehn I don't have to re-attach the EA to the graph to make it work again.

I. check all opening/closing signals are actually executed

L. the stop loss can be set or not

 

I'll require the original code, which I would prefer with comments in it, so that I can understand, thanks.
