I'm currently trading with a demo account, learning some basics and just out of curiosity. I have a question regarding a rapid price move and hope somebody can help me figure out the reason.
I was long on US Tech 100 Cash bought at 7400.9. At 4:10 PM EST the price raised within fractions of a second to 7442.2 only to drop back to 7384.1 at 4:30 PM.
What are the reasons for such rapid price moves in post-close hours? Furthermore I'm curious why the above mentioned prices were only visible in the trading account and were not showing up on the public chart at https://www.ig.com/en-ch/indices/markets-indices/us-tech-100 ?
Thanks for clarification
