Now that Predictions powered by Polymarket is part of the Betr app, a common question comes up fast: is there a cap on how much you can trade?
The short answer is no. The order book isn't built with size caps in mind. It simply pairs up buyers and sellers, whatever amount they're looking to trade.
The catch is that size isn't guaranteed to move cleanly. A large enough order can shift the price as it fills, and if there's nobody on the other side willing to trade at your level, part or all of your order may not go through at all.
That's why it pays to check the order book before placing a bigger trade. Looking at how much liquidity sits at each price point, and how many buyers and sellers are active, gives you a clearer sense of how much size the market can actually absorb.
