Recently, everyone has been talking about modularization and the DA layer, developers are excitedly hyped, while users (including me) are completely confused: what do these terms have to do with me opening or closing contracts? To put it simply, I focus on one main thread: when you place an order, the data must first "have a place to be stored" (data availability), then who goes first and who goes last must "be clearly ordered" (ordering), and finally, this result must "not be repeated" (finality). The more stable these three things are, the more confidently I will hold my positions longer; if they get chaotic, I start itching to make a move—actually, it's anxiety, afraid of missing out, and also afraid of getting stuck halfway. Anyway, my current approach is: if I don't understand something, it's okay, just lower my position limit first, tighten stop-losses, and don't let myself be disturbed by "finality" again and again into insomnia in the middle of the night.
