"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post
"Everything is working great with the API. I love it." - Comment from Calvin
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"If someone needs the best quality data and backfill beyond what their broker provides at a rate that is the best in the industry, I highly recommend IQFeed." - Comment from Josh via Public Forum

"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton

Hello Ladidalimey, here are some instructions once you have the iqf.m file from Matlab.

1. Copy the attached iqf.m file into the following directory (where $MATLAB is the user’s MATLAB installation directory):
2. Restart Matlab
3. At the Matlab prompt type the following:
rehash toolboxcache
If this fails or you run into other issues.  Please contact Matlab support at
