I always find myself taking profits too early. For example, I bought 100 shares of SPY at 131.05 last week, sold it that day at 131.30, event though I had the intent of holding throughout the week. Sometimes I even find myself doing this with short-term trades too, even though I don't classify myself as a scalper. Going long 1 ES and immediately putting a sell order 1 tick above once filled. Anyone else here do the same?
