High and low limit sell

Hello everyone,

My friend and I recently started using binance, and we ran into a problem. We want to have a limit sell for high and low values, but this doesn't seem possible. To clarify: when I buy a certain currency, I use the long position tool to show myself when to sell it. What I would like to do is sell the currency if it reaches the top of the green part or the bottom of the red part. The problem is that a limit sell or stop limit take the currency out of your wallet so if you set a sell a the bottom, you still need to keep an eye on it for the top and vice versa. I would like to set a high and a low value where it automatically gets sold, so I can do some other stuff instead of constantly watching 1 specific currency to see if it reaches a limit. I hope you can help, either way thanks for your attention!
