need a piece of script

no problem. suicide EAs are avaiable from 200$ up...

it's simple, use the function Minute(), for the stoploss tellme an logic

If it's so simple then could you write the script

I would really appreciate ;)

Ok my ea is almost done

now can someone tell me how to make it run only once ?

int start()

{if(Seconds() > 45)
      {OrderSend(Symbol(),OP_BUY,0.1,Ask,1,Ask-10*Point,Ask+100*Point);
      OrderSend(Symbol(),OP_SELL,0.1,Bid,1,Bid+10*Point,Bid-100*Point);


}
return(0);
}

If you want it to open once per minute regardless of incoming ticks then u must design the EA with a loop design, since ticks won't necessarily come every minute. You can read more about this design here -> MQL4 Book -> About Complex Programs.

no it has to run only one time in total

I guess it's very simple but I'm lazy

eg. on next 44 secs I want it to open 1 order in total then the program end

That sort of attitude will not get u very far... Good luck.
