I don't think it is the computers or any viruses. I run with a dual core processor with 2 gb of ram, toshiba satellite. I run AVG and a few other anti-malware and and spybot software. I scan regular. I am having the exact same problems as lee.

I have tried running different browsers Google Chrome, Internet Explorer and Firefox. Firefox seems to do the best, but still has problems.

I have contacted optionsxpress many time about this matter and of course they don't have the problem. I have sent the screenshots of the end of day bad bars and have not received a response from them.

I am going to try to use the extend program to trade. This will take somewhat of a learning curve. I noticed that you can open the streaming charts in the extend program and it may not have the same problem and the streaming charts tab in the quotes. I hope not.

If this continues I may have to consider a different trading platform.

Wish Trades would show us one of those mighty fine SnP charts
