1. I buy Bitcoin using the PC Coinbase platform.
2. It goes up and I want to get out of the trade to make a profit.
3. The trade is still open.
4. I open the trade and the only option is "Cancel."
5. I click "Cancel" and the order is canceled.
6. I don't make or lose any money.
How Do I Get Out Of The Trade Without Canceling It?
Thank you for taking the time to read my post and replying.

First of all, learn the theory of trading before trading on exchanges, and if possible, ask for help if you know anyone who has used crypto exchanges before. If you do not know about trading and want to trade alone you are about to lose your balance absolutely. You either open a trade at the level you want or open a trade at the market price for purchase.
If you press cancel you will have canceled your transaction. Set a buy level for Bitcoin and buy it, then set the level you want to profit from and sell it from there. Sometimes things don't go the way you want and you may lose. Remember canceling means throwing away profit or loss. When applying the advice you get here in practice, do not forget to get help from your friends who have traded in the stock market before.
