Why can the price still plunge straight through even when there are huge buy orders sitting on the order book?
When I first started trading small-cap coins, I’d see millions of dollars’ worth of buy orders stacked below the price and feel incredibly reassured: with a buy wall that thick, the big players must be defending the price. If it fell, someone would catch it.
It took me a while to realize that what the order book shows is intent, not a promise.
I once went long on a low-float coin traded through perpetual futures. The orders from the best bid down through the next nine levels were so massive they dwarfed its usual trading volume.
I thought the bottom was locked in. But as soon as the price got close, the buy orders started disappearing, one level at a time. When the real selling hit, the so-called buy wall vanished in seconds.
It turned out those orders could have been dynamic quotes from market makers, or simply a way to create the illusion of support and lure retail traders into entering early.
Even if the buy orders actually get filled, that doesn’t mean anyone is bullish for the long term. A market maker may be holding short positions at the same time, buying spot only to keep inventory neutral. A large trader might also use some of their funds to prop up the order book while gradually unloading tokens at higher prices.
To tell whether support is real, don’t just look at the size of the orders. Check whether trades keep going through when the price reaches them, whether the cancellation rate is high, whether aggressive selling is repeatedly absorbed, and whether the price quickly recovers after the trades are filled.
Remember: money displayed on the order book can be pulled at any time. Real support has to withstand selling pressure. A buy wall can create a sense of security, but the price reaction after trades go through is what really counts.
