There is a saying that goes very well, you can win 10,000 times, but as long as you lose once, it's GG. You cannot casually open a single, you must be cautious every time.

Greed, hesitation, irrationality, explosive mentality, truly original sin. Last night could have taken profits, but didn't; this morning the market changed direction without judgment, holding onto positions all the way, lacking rational analysis. Clearly a significant rise in volume, yet it didn't break previous levels. Those who should have cut losses are still full of hope. Truly foolish.
