Modification of an existing expert advisor to take and manage trades effectively

I have an EA I would like it to be checked, modify and resolve some issues with it and repair it to work perfectly.  

What to be checked are:

1. When a trade is opened with the EA after few mins the EA will close trade. Please check and resolve it

2. Check the SL implementations  and ensure they work perfectly. Check the calculations and formulas used. The Risk percent(amount) should be the amount that could be lost if the trade hits stop loss.

3. Lot size calculation and ensure it is working properly.

4. Check the Break Even. The calculations, implementation and ensure it's working properly

5. Check the Trailing Stop Loss. The calculations, implementation and ensure it's working properly

6. The Risk: the percentage amount risked should the the amount that could be lost if the price hits the stoploss settings. please check for possible errors in the formulas used and ensure it's working properly.

7. The News, Check and make it possible to be scrolled (left to right and up to down) so that the news displayed could be read. Date format should be changed to day:month:year

General check to ensure everything is ok
