Code Conversion from PineScript to MQL4 or MQL5 - Expert Advisor

I wrote a strategy in PineScript that I am using to trade manually. I would like a fully functional automated trading robot to let it trade on my account automatically and so I need to convert it to MQL5 or MQL4. 

I added lot of 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. 

For now, I didn't use MQL5/MQL4 enough to know the capabilities of this platform, so if some options or possibilities are not easily convertible to MQL5/MQL4 I expect from you to warn me before accepting and developing this Expert Advisor.

What is expected in terms of materials: 

1. The MT5 or MT4 EA must include the indicators with the same options panel as TradingView script : An Expert Advisor behaving like 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 MT5 EA must match the data 100% as TradingView (with the same data provider of course)
3. The MT5 EA must return 100% the same results as TradingView script (with the same data provider of course)
4. The source code of the Expert Advisor with detailed comments (well documented) : as this script might evolve over time, it will need to be easily understandable in the future.
5. As I'm using this strategy to plot some indicators on my charts, it will be required 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).
6. VERY IMPORTANT: The MT5 or MT4 EA must be errors free! A serious work, as I don't want to lose 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 developing skills: 

1. A Proactive developer with enough experience to offer me some improvements options.
2. A Proactive developer able to warn me if some options are not easily convertible to MQL5/MQL4 and experienced enough to find alternatives solutions.
3. The possibility to backtest the EA, to be able to customise the inputs depending on the Pairs / Stocks / Timeframes traded

What are the Indicators 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. The option do determine the lot size according to the account size.
3. 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 X % of the position and SL = TrailingStop based on Average True Range). We decide to precise this together with the developer.
4. Everything that could be native in Tradingview and not in MQL5/MQL4 (as I don't know MQL5/MQL4 for now)

IMPORTANT :

It is important for me to remain owner of the code, and that it is neither sold nor distributed elsewhere. All intellectual property and rights to the final product and any/all parts thereof will remain mine and cannot be used elsewhere.

This EA will be used on multiple pairs / CFD with various timeframe and settings so it need to be able to do so.

I'm also looking for a long term business relation, so if you do a good job, I will continue to work with you in the future. 

PS : the price will be discussed in Private Message
