Has the schema markup been broken for three months with no one noticing? A true story from an SEO veteran

Despite having over 16 years of SEO experience, it’s difficult to spot invisible errors. Here’s a story that was shared on LinkedIn by Nick LeRoy.

He also added the red candlestick chart, which nobody likes to see.
