After the market starts to move up, the sentence I trust the least is: “It’s basically the same no matter where the main trading pairs are opened.”

The faster the rally and the more consecutive liquidations wipe out short positions, the clearer the real differences between different venues become. Normally it looks like everyone has quotes; but in those few minutes when you chase orders, add margin, set stop-losses, or flip positions, things like order book depth, funding rates, trading slippage, fee tiers, and matching stability all turn into costs at the same time.

When many people replay trades, they only ask whether their direction was correct. I think that’s not enough. In contract trading, a more mature question is: with the same judgment, if you execute it in different places, has the risk-reward ratio already changed?

So the value of a Perp aggregator is not to yell long or short for you—it’s to lay out the execution environment before you place an order. First choose the asset, then compare the depth, fees, and costs across different venues, and finally decide where this trade should go. That’s exactly what Perpex/PerpEX is doing.
