Yesterday I was analyzing whether the position at 86500 was suitable for a long order, but today I couldn't resist and opened a long positions at 88150. It seems like only a difference of over 1600 points, but the actual effect is completely different.

The market performance at that time made me overestimate my judgment a bit. I originally thought it wouldn't drop, so I opened a position early. Unexpectedly, it still came close to my set stop-loss line. It almost broke through.

After all this fussing around for a whole day, the long order has been hovering around the break-even point, with zero floating profit. It sounds simple, but it has resulted in a loss of nearly 2 points of volatility for nothing. The lesson from this operation is very clear: the key support level is where one should take action, and being too anxious has instead become a burden.
