Suddenly a red dot popped up on my phone alert saying "Whale address added to position," so I clicked in and found the trading was pretty fragmented... To put it simply, before copying trades, you need to figure out whether they are building a position or hedging; otherwise, you might think it's a "signal," but it could just be them opening a reverse position on the other side to lock in risk. The simplest thing I do is first check: whether they have synchronized moving margin/stablecoins into the contract, whether spot and perpetual are in the same direction, and whether the positions are being gradually built up in batches. On-chain data is actually more straightforward than looking at candlestick charts; just pulling the address's fund flow makes it clear. Recently, modularization and DA layer discussions have been heated again, developers are excited, users are confused... But during these narrative phases, whale operations are more likely to "look like" something, but in reality, they are just arbitrage or risk control. Stay calm first, and don't be a plot enthusiast.
