I just failed to execute a trade and feel pretty stupid... Clearly, it's a liquidity pool with average volume, and I impulsively set a high slippage. As a result, the transaction was eaten up in a few seconds in the mempool, and the next jump price immediately drifted away. Looking back, there were a few trades earlier in the queue that blocked the way. Honestly, it's not "being targeted," but rather my order placement was too casual: if I want to be quick, I should split into smaller orders or just not chase that one, leaving some room to maneuver. By the way, over the past couple of days, everyone has been speculating whether the project will migrate during the chain upgrade/maintenance, but I'm actually more worried about thinner depth and more chaotic matching during such periods... That's it for now, I'll continue analyzing trades tomorrow.
