Price differences between exchanges exist but they’re usually tiny and disappear fast because of arbitrage traders. The bigger issue is understanding which exchange has better liquidity for the specific stock you’re trading, because low volume means wider spreads and worse execution prices. Real-time data feeds cost money too, most free apps show delayed quotes which are useless if you’re trying to catch price differences. You need something that aggregates live data and shows you where the best bid and ask prices actually are at that moment.

A lot of beginners assume they can just hop between exchanges chasing pennies, but transaction costs and currency conversion fees eat up those tiny margins fast. The real value is seeing the full picture of where a stock is trading and what kind of volume is backing those prices. Thin order books mean your trade moves the price against you before it even fills. You can use this stock picker app here https://stockpickr.app/ . It tracks prices across exchanges, shows liquidity depth, and helps you spot where you’re actually getting the best execution. Takes the guesswork out and keeps you from overpaying just because you only checked one exchange.
