hey @LGrant
As @Vlad indicated - the in app pricing is delayed by a few minutes. Our platform fetches new pricing from the CBOE exchange every two minutes and the app has some caching in place which adds extra latency. If you were to restart the app you should see data within the last two minutes.
When a trade occurs the price you get is within the bid and ask price of the London Stock Exchange and not related to the pricing data you see in app.
Hope that makes sense!
