The market's all over the place right now, company stocks are dropping one day and shooting up the next. Prices on different exchanges are shifting constantly and if you're paying attention you can actually make moves on those gaps. Buy low on one exchange, flip it where it's trading higher, pocket the difference. Where can I track which companies have better pricing on which exchanges right now versus where they're trading worse? Need something that shows the spreads in real time so I can catch opportunities before they close.
