I have these two on my IG watch list and noticed a massive gap up with RUSL even though normal Russian market didn't experience it and JNUG a massive gap up with the current price around $20 from $2 but not showing on the charts. Is this legit or just an error? I don't think RUSL is an error as trading continued after the gap up on the chart.
