If you operate according to your own system rules, and the fund management of opening and closing positions conforms to the system rules, there is no subjective change or operational error, then this kind of transaction is not intraday trading.

On the contrary, many transactions that violate the rules of the system, even intraday trading, are things that avoid giving play to their advantages in the long run, and profits and losses depend entirely on luck.

If there is no trading system, it is difficult to define whether it is intraday trading.
