Hi GP, Bullcharts Market Depth has been working fine all day for me, (I tried the ticker codes you mentioned) but I know what your talking about, and have experienced what you describe before. They are aware of the issues, and are working towards a fix. I believe some of the issues are related to Microsoft's Dot Net Framework...life's not easy being a programmer at times. I'm using version 5.0.6, What version are running ?
Most providers will supply IRESS free of charge, if you do enough trades per month (you pay for it either way).
