Coder needed for Corrections of functions and Bugs in two existing EA’s for MT5 developed by Outside Developer

I have a EA for MT5 platform programmed by an outside developer very recently. I found out several miscalculations done in the code to achieve my proposed logic. EA is currently functioning with at 60-70 % accuracy. So I want a party to rectify these errors. This EA mainly includes CCI, RVI and Stochastic Ocilator.

This EA is a continuous development project with addition of indicators and logics. Will take several months complete whole project. There will be 1 or 2 modifications per month till that time. So I am looking for a party who can work with me for several months.

Each time I will create new project and  there will be payment for each part completed. I am planning to add Standard deviation Indicator Soon after completion of error correction Project (this one). Which Will be followed by Adaptive Moving Average Project. So on.

All the Bidders must reply with mostly available time and time zone they are living ( GMT Time Zone). So I can select a party based on my working time. I used to work outside during daytime and forex is on balanced time.

Thanks.
