Code Conversion from PineScript to MQL5 - Expert Advisor

Hello dear developpers :)

I wrote a strategy in PineScript that I am using to trade manually. As a lot of people, I would like to let it trade on my account automatically and so i need to convert it to MQL5. 

I added comments /documentation to my code, but as I know my code very well, my comments might not be clear enough for you, so feel free to ask me if you encounter any difficulties. 

At the moment, I didn't use MQL5 enough to know the capabilities of this platform, so if some options or possibilities are not easily convertible to MQL5 I expect from you to warn me before accepting and developping this Expert Advisor.

What is expected in terms of materials : 

1. An Expert Advisor behaving similar to the one on TradingView (Panel with customisation of Indicators Inputs, customisation of Money Management Inputs, Customisation of Trade Date and Time Session, Customisation on Lot Size and Commission, Customisation on Trade Order Type, Customisation on conditions to enter a trade and of Course ENTRY and EXIT SIGNALS)
2. The source code of this Expert Advisor with detailed comments, as this script might evolve over time, I will learn the basics of MQL5 to be able to customise it in the future and I will need those comments. 
3. As I'm using this strategy to plot some indicators on my charts, if this option is not available for MQL EA, i would like to get this bunch of indicators included as a side development to be able to put them on my charts. It allows me to do a survey of the positions taken by the BOT (these are relatively simple Indicators)
4. VERY IMPORTANT : A serious work, as I don't want to loose time looking for potential errors in code (I already did this on my actual system !). So if you need more time, we can see it together ;) 

What is expected in terms of personnality : 

1. A Proactive developper with enough experience to offer me some improvements options.
2. A Proactive developper able to warn me if some options are not easily convertible to MQL5 and experienced enough to find alternatives solutions.
3. The possibility to backtest the EA (if not offered by MQL5 - I need to familiarize with it), to be able to customise the inputs depending on the Pairs / Stocks traded

What are the Indicator used in the Strategy Sytem : 

1. Williams R%
2. MACD
3. Moving Averages
4. ADX
5. Squeeze Momentum
6. ATR System
7. Stochastic RSI
8. SSL Channel
9. CCI

What is not in the actual System but will need to be included in the EA : 

1. Every Native Function in the Strategy System of TradingView (Lot Size Calculation, avoid martingale, Type Order (Market, SL, Limit), Slippage
2. At this state, the BOT is working with 1 TakeProfit target, I would like to add the option to have 2 TakeProfit targets, and move the StopLoss accordingly (when TP1 hit close half the position and SL = BE or TrailingStop)
3. Everything that could be native in Tradingview and not in MQL5 (as I don't know MQL5 for now)

As I'm from France, my english is not the best, even if what is important is to understand each other, if you speak French that will be a plus !
The rest will be discussed in Private Message before accepting any offers.
