Modify Current EA

I will need to update my current Expert advisor. 

The expert advisor has some errors which require to remove all the errors and then require to add below functions/parameters 

1. Position size based on Risk Exposure. (Example attached in picture) (i.e require  automatic position sizing based on risk % and stop loss value)

2.  Stop loss & Trailing stop  (Must work as below)

If the position is -1 Trailing is off - At this point only Stop loss should work.

If position is 0 Trailing stop = Stop loss

If position is >0 or in profit then Trailing stop should work.

3 Take Profit

4: A box requested on the chart about the EA with below information

Total open positions

Total risk

Total Equity

Chart timeframe

additional details if programmer think necessary

 Its an easy job and I guess a programmer should be able to complete in couple of hours.

Let me know if you can do the job and I will send you the EA
