are there any indicators/scripts like this?

hi...i am looking for a indicator/script/ea which is simply just a horizontal line and when the price reaches that line a trade is placed? maybe 3 horizontal lines on chart one for open, one for stop and one for set profit. if the line are moved then the order should be updated etc?

thanks.

That is totally possible with Metatrader, but you'd need a few programming skills to sort it out for yourself, it's not much work to do one so I would expect you'd be able to find one on the net.

To change a stop loss from a horizontal line you would need something like this

StopLoss=ObjectGet("line", OBJPROP_VALUE)

OrderModify(OrderTicket(),OrderOpenPrice(),StopLoss,OrderTakeProfit(),0,Blue);
