I need an EA or a Script to automate my manual work.

Hi All,

  I need an EA or a Script to automate my manual work. My "strategy", or what I'm doing now looks like this.

I decide to open a trade:    

1 lot - 10 pips tp   In the same time I put a pending order with the same details, after tp+spread, so I don't end up with 2 open trades at the same time. 

       - 10 pips sl    In the same time I actually choose a pending order instead of sl, a pending order with the same details but 3 lots, 1 lot will "close" the loosing trade, 2 lots remaining.

The EA to open the first trade when I activate it, to carry on with setting the pending orders one after tp and one as sl, and if the trade goes to tp every time to repeat indefinitely, if the trade goes to sl every time to stop after a number of times I setup.  In the same time, the EA needs to cancel one of the 2 pending orders if the other one has been activated.
