Latest adjustments to EA time sessions

A few months ago, a developer has been working on an EA for me. This is almost finished, but a few minor adjustments still need to be made and a few things that are not yet running properly need to be checked. For clarity I will attach the specification file. The strategy is explained and the functions that must be present are described. I have an mql 5 and an ext file available. Further work can be done to complete the EA completely. Some things that need to be checked are: large breakout candle and how we handle them and the overnight zone needs a small change. Furthermore, a few minor adjustments to improve the stability of the EA. I have set the amount of money to 30 dollar, that's really much for this task, but I want in return a week of testing with a demo version to see if everything works fine. 

I am looking for someone who masters building and optimazing EA's. When the EA is ready within a week, there will be an additional payment.
