All trades are entered with stop orders. The entry prices are shown for each order of the day. On some days the open price is above the entry price for long entries or below the entry price for short entires. These days do not occur often. But if it happens simply change the entry order type from a stop entry order to a limit entry order. The order may or not fill.
After an entry has filled a stop loss order is immediately placed at the stop loss price shown for each order. The stop loss price is not adjusted during the day.
All open trades are exited with a market order at the end of the session. No trades are ever held overnight. By far most trades will exit normally at the end of the session.
The system can be profitably traded as described above. However, a discretionary trader can use additional indicators to exit open positions before the end of the day. This can be very useful for days with market reversals. Waiting to the end of the session can sometimes give back profits.
It is important to carefully apply your personal risk management in determining how many trades you take.
