Opening more than one order


Hi Everyone. Im trying to develop a expert to use on crash500 market, The aim is for it to open a sell order once the RSI is on 90 and then open a second and a 3rd order about 4 candle sticks after the first order was placed. Basically the first order to open when RSI is on 90 then open a second order when RSI reaches 92 and a third order once RSI reaches 94. I managed to get it to open on RSI90 but now im not sure how to create for the other two orders to open. Is there anyone who can please tell me where I went wrong or who can assist.I would also like to add a trailing stop so that when the order is in profit it should close after about 3 minutes or 3 1minute candles on crash500.  Please advise on what I can do. Also how do I get it so that the input will show once I load the expert in order for me to change the lot size and the SL and TP
