Today I was once again too stupid myself... I wanted to copy a small rebound, but I impulsively placed a market order, and the slippage directly taught me a lesson on the spot. To be honest, it's not that the direction was wrong, but that I didn't have enough depth and forced it, like ice cream melting in a second when it hits heat. After reviewing: don't place orders when emotions are at their hottest, split the orders into several parts and wait, or simply reduce the position size. I'd rather miss out than force that "pleasure" of eating it. Recently, I heard that some regions are raising taxes and tightening compliance, then loosening again, causing deposit and withdrawal expectations to fluctuate, liquidity to be pulled out, and slippage to become even more exaggerated... Anyway, I’ll set my stop-loss to be fixed, don’t be too quick to act, taking it slow might help me last longer.
