Just realized how stupid I was: I clearly wanted to “test a small order,” but once I saw the order book looked pretty thin, I got antsy and went in all at once—just full send—while the slippage was set in a very casual way. That fill felt like someone shoved me from behind… To put it plainly, it was because the depth wasn’t enough + my order placement rhythm was way too rushed, giving others the chance to eat my spread. From now on, I really need to be a bit obsessive-compulsive: split the orders first, wait for a slice of liquidity to come back, and then hit the trade—otherwise these “it looks pretty much the same” moments are the most坑. Also, it reminded me of that recent chain game setup with inflation + studio bots: the coin price spirals down, and the depth disappears just like that. Anyway, I’ll slow down first and come in steadily.
