Urgent help. Convert Indicator to EA (Auto Trader)

 
I am a programmer but newbie in mql4 programming.
I am trying to create a EA (auto trader) regarding an indicator.
I attached the indicator. This indicator gives good trend signals.
Now wanna make a auto trader regarding the trend signals.

Algorithm:
==================================================
If DOWN SIGNAL then open SELL order and close previous BUY order
If UP SIGNAL then open BUY order and close previous SELL order

continue ....
==================================================

I wanna just manual trading to auto trading regarding this indicator.

Can anybody help me?? I tried but not get the result
I think it would be a good auto trader. Please help me.
