I discovered a shorting opportunity and was strongly tempted to increase my leverage, even felt quite impulsive about it. But I can't. I must adhere to trading discipline internally. It has proven that following trading discipline is the right call—the price rallied back up. If I hadn't stuck to it, I could be pulling my hair out now, risking significant losses or even liquidation. By maintaining trading discipline, I secured the benefit of keeping my mindset in an invincible position.
