Hello, this is the statement I am writing to get the closing prices of 80 stocks:

 

donnees<-blp(conn,mblist,"PX_LAST",startDate,endDate)

where mblist represents a list of 80 stocks

I set the endDate to yesterday

When I set startDate to beginning of september it returns me the right value but when I want to set it at january 2005 it returns me the following error:

"Error in blpGetHistoricalData(conn, securities, fields, start, end, barsize,  : 
 Call to BLPSubscribe did not return any data!"

As it is working for one smaller case I am wondering if it's not a size limitation problem. If that is the case what is the limit. It would slow down my code a lot if If I have to call it for each stock, do you another way to do it?thank you!

Anna
