StockCharts are not posting or old posted charts on IHUB. Please have them fix it. It looks like it is an issue with the hosting website, not IHub. They may not allowed embedding of those charts, may be frequency capping them, or some other issue, I noticed the change in chart URL's last month but did not think much about it. The only way to get a chart image now is with "c.stockcharts" in the URL. http://c.stockcharts.com/c-sc/sc?s=TREP&p=W&yr=0&mn=4&dy=0&i=p8300256585c&a=634687985&r=1545533761425 http://stockcharts.com/c-sc/sc?s=TREP&p=W&yr=0&mn=4&dy=0&i=p8300256585c&a=634687985&r=1545533761425 This image uses the c.stockcharts http://c.stockcharts.com/c-sc/sc?s=TREP&p=W&yr=0&mn=4&dy=0&i=p8300256585c&a=634687985&r=1545533761425
