Just reviewed last night's failed trade, and I was still too impatient. The order book looked quite smooth, but in reality, the depth was dangerously thin. I also set the slippage too tight, and my order was swept away in an instant. As soon as the price moved, it was immediately pushed back, paying unnecessary fees, and my mood also took a hit. To put it simply, I didn't control the order placement rhythm: I should have split the orders into smaller parts, waited for one or two confirmations before acting, and preferred to be slower, at least I wouldn't scare myself. Recently, many people have been using ETF capital flows and US stock risk appetite to explain crypto price fluctuations, which makes me even more anxious... But for me, it boils down to one word: stability. First, set parameters that let me sleep peacefully.
