giles, GTS, thank you! But I don't see the IP 206.106.137.3 of www.interactivebrokers.com at the end of your traceroute. How can you reach this site then? Are you sure you see fresh contents and not only pages from the cache of your browser?

Could somebody who can reach the ib .com site send us please a tracert to check whether sprintlink is the cause of this issue.

kiwi, tintin, can you pls post a traceroute? (enough for some hops far from your mashine)

thx. I talked to my ISP they said they couldn't do anything because this was the only site that had problems. meanwhile, I tried www.interactivebrokers.de and www.interactivebrokers.co.uk this ones are fast as usual. ping, tracert also ok with them. The problem is that the forum and...

Thank you guys!

I bought some MRBK before market close on previous friday, before it has been merged into PNC after close. Because of the completed merger there exists no MRBK symbol any longer, previous MRBK owners should now hold PNC instead. The problem is that I still hold MRBK shares on my IB...

I don't like point 4 either. Owning the system means you can do with it whatever you want. Why would you share profits with the developer of a profitable system, if you have full insight to the system and also all the rights on it?

many thx for the response. I would like to have aggregated totalview data for some liquid stocks (aggregated volume for each price level) for backtesting and research purposes (market microstructures PhD topic). As I saw nasdaq makes these historical data available only for redistributors...

Anyone pls? :confused:

Where are these data available for a non-pro or researcher? thx, torel

Calibrate your trading system for a 5% max. drawdown and automate it by setting up an ATS. Let it run with $5K. Then, you only have to stay away from manual order entry. Practice this for a half a year test period. If the system is consistent with backtest results in this test&practice period...

Trouble maybe because of the SingleBook integration on nasdaq? Should be completed soon...

Do you know any provider where I can download TotalView data for nasdaq stocks for backtesting purposes? thx, torel

Here some more evidence of significiant differencies between real and backfill high/low/close prices for GOOG and SNDK (very liquid nasdaq stocks). The four columns show for each bar 1. the timestamp of bar 2. diff high 3. diff low 4. diff close Differences for a bit less liquid...

I'm curious what traders with Ph.D. degree say about how useful are strong scientific abilities in successful trading. I'm an ongoing doctor student (informatics) and I intend to establish skills during the course that can be beneficial in development of trading strategies. (I do not want to...
