Usage Limits

If you encounter data limits while using the Bloomberg Terminal please note:

You can have no more than 3500 real time fields open at the same time. If you exceed this limit you will see "NA Limit" as error message and you need to delete some securities/fields in order for the error message to disappear and to see the values. 

We also have a daily limit. The daily API limit is 500,000 hits/per day. A "hit" is defined as one request for a single security/field pairing. Therefore, if you request static data for 5 fields and 10 securities, that will translate into a total of 500 hits so try to refresh just the portion of the spreadsheet that really needs to be refreshed and avoid refreshing it all or reopening it many times a day. 

There is also a monthly limit, however only about 0.4% of the user database ever go over this limit. The limit is based on unique securities and depends on the type of data being downloaded. 

Please see the document below for information on managing data usage limits.
