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
What don't you understand, it's very simple to get it right maybe you need to read some gaurdlines on youtube depending on the exchange you want to buy or execute the trade. For instance its very simple to trade on Binance exchange, I don't know what exchange you want to place the order. So checkout for some videos on youtube for best knowledge.
