It doesn't matter what frame you're working on. The main thing is that there would be a profitable trading system. Advantages of the scalp: you follow the market(in fact, you don't need a big analysis of the direction of price movement); more signals, therefore you can earn more. But you can't work without a stop. Cons of the scalp: emotional and mental stress, sitting at the monitor. But it's justified if you earn money. Advantages of medium-term trading: less emotional and mental stress; you don't have to sit at the monitor all the time. Minus: fewer signals, longer wait; requires more analysis of future price movement( although large capital still breaks the technique). Conclusion: you can earn both on the scalp and on the medium term; you can merge both on the scalp and on the medium term. The main thing is to follow the trading strategy. Everyone, taking into account their psychology and life circumstances, chooses the most suitable method of trading.
