Scalp trading and swing trading mainly differ in the time-frame. Scalpers enter and exit their positions quickly with a holding period of just a few seconds or a few minutes which allows them to perform hundreds of trades in a day. Swing traders, on the other hand, make fewer trades but hold them for a slightly longer time frame which may be from a few days to a few weeks.
Now as per the question of mixing these two strategies, I think it’s a bad decision. You can perform both the strategies on two different accounts but if you are thinking of implementing both of them on the same account, you are most likely to get confused. Both the strategies are based on different parameters and when you make your style flexible, you’ll end up going against your rules. You’ll take one trade for scalping but when you’ll realise that it is not in your favour you’ll try to keep it longer for swing trading.
