Change Indicator buy/sell signal to EA robot

Hello pal,

I am a newbie of making an EA but I need to convert those signal from the indicator to an EA Robot. In the indicator, arrow signals are not generated with index buffer but generated with object create, that is the difficulty that I cannot face on...BTW, hopes pal can convert it to a EA, thank you very much!!

 1, Yellow arrow -> Buy Signal

 2, Face Down Blue Arrow->Short Signal

 3, Face Up DodgerBlue Arrow-> Cover Signal

 4, White Arrow->Sell Signal 

Signal Generate code : IntradaySystem V3.0 (ln2733-ln2777) 

 In the indicator, i set two target and the target2 would be the take profit level. Unless the order does not meet the stop loss level or the take profit level, then it will Close the order at the opposite signal.

e.g: a,Order Buy->Short Signal  occurs->Close Buy order->Open Short Order

      b,Order Short->Buy Signal occurs->Close Short order->Open  Buy Order

      c, Order Buy->Buy Signal occurs->Ignore last signal, vice versa(Order Short).

      d, Order Buy->Sell Signal occurs and didn't meet stop loss/take profit level->Close Buy Order

           e, Order Short->Cover Signal occurs and didn't meet stop loss/take profit level->Close Short Order

P.S.: 1,Only one trading order in the same period. 

       2. You may need the Waddah_Attar_Explosion Indicator for testing.  

Hope you may give me a favour, it may be easy for you~ Thanks.
