Today's order was indeed a mistake; I bought in 15 seconds early, which led to paying a relatively high fee. So when the profit was equal to the fee later, I panicked. Weak as I am, I stepped in and took early profits. Then, driven by greed, I thought about making up for the first wave of losses, so I re-entered at a rather unfavorable position. There are still many areas for improvement. Keep it up!
