Yes, a trader should always control risks. You can use a small leverage, and also set stop losses in your trades. I don’t see any point in stretching out a loss if your trading strategy has already shown that the trade conditions did not work. And it’s better to close a small minus in time than to wait for the price to reverse someday. But will your deposit survive until this reversal??I think it’s about how much portion of your capital to risk for gaining profit? If it is so, you have to be miser about using leverage in your trading.
