Thank you for the responses' but I didn't understand edgycorner answer.
I can't do 2 orders on the same money at the same time, and of course I can be on it 24\7 and do the right one when the time comes (transforming myself into a bot haha), but I want one order to cover both ends.
The reason I want it is because I think the asset will go to 50$ so I don't want to buy at a 100$, but it things change I don't want to lose the train completely and want to "stop" at 130$.That's it. It's not that complicated of a use case and it's weird there isn't order to that
