Yes that is the disadvantage but check for how many traders that won't use stoploss and see how many times they will keep regretting of losing the balance or fund and try to recredit the account. If you don't use stoploss, you are likely to be losing your capital. Except there are other proven better ways to trade and be profitable than using stoploss.
That is true though, but I only use stop lose when I leverage, I can consider using stop lose for 3x leverage or above, but for 2x and 1x I do not use leverage.
Also if I open position for swing trading, that is definitely 1x or 2x and k do not consider to use stop loss. But traders will have different opinions about using stop loss or not but in most cases, I do not use it.
