Script to allow a sequence of trades.

Hi, Im looking for a quote to make a script that will take trades over a number of trades.

So I would look to enter long price specify lot size and sl at same time set short price lot size and sl as a sequence of 6 to 8 trades that of course will only become active once trades has hit sl.  Example trade 1 hits sl trade 2 opposite is triggered if that hits sl trade 3 is triggered and so on... I also want the ability to enter a price point where if hit PRICE SL moves to Break even minus spread number. Basically it is box trading with other parameters etc.

Thanks

Ian
