Non-Pro Members cannot request more than 1 chart per second on average over any 15-minute period.
Pro Members cannot request more than 2 charts per second on average over any 15-minute period.
There is a limited number of charts that we can provide during the day. While that number is very, very large, it is not infinite. We depend on our users to request a “reasonable” number of charts during a given period of time. For non-Pro members, we define “reasonable” as up to 1 chart per second on average over a 15-minute period (i.e. 60 charts per minute). Pro members can request up to 2 charts per second (120 charts per minute) on average.
People who open a large number of auto-refreshing charts can run afoul of these limits if they are not careful. If you have more than 15 charts refreshing at 15-second intervals, you are requesting more than 1 chart per second and are violating our policy. If you must have lots of charts auto-refreshing, we recommend reducing the refresh interval to 30 or 60 seconds.
If you exceed these limits, you will see a warning message in place of your charts. The warning message means that you have requested too many charts recently. You need to reduce the number of auto-refreshing charts that you are requesting. Once you do that, the warning message will disappear.
NOTE: If you ignore the warning message and continue to request an excessive number of charts from our website, your account may be disabled.
