You can not if you use only one account.
It's possible if you use multiple accounts on one exchange, like you use a first account with trading positions used x2 leverage; a second account for trading positions with x5 leverages; and a third account with trading positions used x10 leverages.
By using different accounts and different leverages, you can manage your entry and exit as well as risk better. I mean you can calculate your entry, exit and liquidation price better, but this method contains risk of exchange policy. Using multiple accounts are likely not accepted by their ToS.
One thing I dislike about trading crypto on exchanges is this, you can’t get to maximize your wins after seeing a very good trade to maximize and go all fully, like full margin or so. Forex trading does not work that way but one thing that distinct them from each other is that one of them pose more risk while the other makes you decide the risk you’re willing to take from onset. You can’t increase your risk to reward ratio while trading forex after seeing an opportunity that warrants so, but in trading crypto from exchanges, what you decide from beginning as your risk to reward ratio is what you’ll get unless you exit the trade and enter back using more leverage which is also a risk on its own. It would be better if they look more into this and make one to add more positions on same pair when already in a trade. Or do they do that to limit the risk one can take in a trade?
