IQFeed connection not working with Matlab Aug 24, 2013 12:15 PM
(Total replies: 5)
Trying to get the S&P500 stock components with below logic: history(q,char(stocks(n)),{'01/01/2011','08/23/2013'},'Daily'); where stocks is a cell array with all 500 components. put this in a loop, with 4 sec delay, and the history command will stop returning the total amount of days for a specific symbol. For example: Symbol: EXPD, Nr.of days collected:665 Symbol: EXPE, Nr.of days collected:665 Symbol: F, Nr.of days collected:1 Symbol: CVS, Nr.of days collected:665 Symbol: CVX, Nr.of days collected:1 Symbol: CBE, Nr.of days collected:665 Symbol: CBG, Nr.of days collected:14 each time the program will reach these particular symbols, the history will stop returning the proper amount of days requested. The workaround is to close-down Matlab (IQF connection may remain open) and open it again. Are there any troubleshooting means, any diagnostic commands that could help - for example assess if the connection to IQFeed is still operational ? I assume I'm not the only one trying to download the components of an index from within matlab - are there any working samples available anywhere? Thx |
