Most people judge exchanges when nothing's happening. Big mistake.

Real test? When everyone's panic trading at once.

Just checked $BTC perp book on @okx during the European session chaos. Deep liquidity both sides. Actual size sitting there, not ghost orders.

Nobody cares about execution quality until you get absolutely rekt by slippage on a volatile move.

That's when you learn which platforms actually have real market depth vs which ones are just UI with no substance.
