This 3315 level can still be held and waited for a reversal signal before exiting, but the main focus is on practicing with small positions, with profit-making as a secondary goal. Plus, since I have to wake up early tomorrow for work and mining, it's okay to take profits and run. Currently, both trades have a 100% win rate, with a total profit and loss ratio of 0:40 points, and the overall stop-loss and take-profit ratio for opening positions is 1:4.
