Staring at the steeply plunging curve on the screen, the heat of clicking "confirm increase the position" still lingers on my fingertips. I once thought the courage to buy the dip could bring the surprise of a rebound, but I nailed my greed at the highest point of the Candlestick Chart.

It turns out that every impulsive Heavy Position is a tuition fee paid to the market for understanding.
