Just got educated by myself again... Thought I was just going to place a small order, but I didn't watch the slippage, nor did I check the depth carefully. When the market moved, I chased after it, and the transaction price was way off from my expectations. To put it simply, it’s not the market tricking me, it’s that I was too hasty with my order: seeing green/red made me itchy, and I didn’t wait for the order book to fill in a bit more.

In the past, I used to love rushing in all at once, thinking "it’s only a few seconds anyway"; now I’d rather be a half beat slower, split the order first, set limit prices and wait a bit, if it doesn’t work, then cancel. Don’t compete with bots for that little liquidity. Recently, funding rates have been extreme again, and in the group, people are arguing whether to reverse or keep squeezing the bubble. I might as well treat myself as a rookie: don’t bet on the direction, just figure out the slippage and depth as costs first. That’s it for now.
