Developer to build a simple EA

Hello developers, I need a very simple EA(MQL5). I will be opening multiple positions long and short on the same chart. I need this expert advisor to accomplish two tasks:                                                                1) Calculate the total of long positions and total of short positions And the difference between long and short And display them on Chart.Example: I have opened 2 long position of 0.1 and 0.5 and five short positions 0.1, 0.1, 0.1, 0.1 and 1.3. So this experts advisor should display on chart The following: LONG= 0.6 SHORT=1.7 DIFEERENCE=1.1(in green if long exceeds short and in red if short exceeds long)             2) equalize LONG and SHORT by opening long positions or short positions that equal to ‘DIFFERENCE’ when:  A) price hit certain level(input) or  B) certain level of equity has been reached (input)
