A traders should not also focus only on scaling, they can open a position for scalping, but it can still go wrong, but there should be a defense in such a way even if the scalping do not favor them, they still know the market is most likely to go in the direction chosen, then turning it to day trade or swing. But if this is not done rightly, it would have been better for a trader to just close trade after losing some amount of money in few minutes but depending on the RSI.
You don't look like understanding what scalping is. It is usually between 1 to 15 minutes kind of trade and you know the market is very volatile. On a very good day, a scalper may not use stoploss or is not able to set it on after entering for the trade because of volatility. If a scalper get it wrong I think the best is to close the lose because if allow a losing market to roll on it may happen against the trend and that can roll out the balance of the trader.
