Yep, you made yourself a bit more clear. Just a bit.
So you want a price to be in some range and plant a buystop/buylimit or sellstop/selllimit depending on conditions.
You want to decide range by yourself and you want the order to be closed after some point of time you decide yourself. And you want that order placed when RSI is in 70+ or 30- area. Or do you want to open a market order?
