    Whats best for serous ATS: lightspeed vs rithmic vs DAS

    So this is the more casual setup ... I'll bet your "order entry server" is a middleman who routes it off to the exchange. Have another middleman who consolidates and passes you the market data. The data feed is the likely bottleneck (know where your data feed is connecting to ... does nxCore...

    If everyone is selling gold/silver why is it hard to buy now?

    Simple, the small guy is buying (apmex), but the big money is selling (futures) Gold has been disconnected from real supply and demand for a long time now, due to a lot of big money coming in. It is historically unusual and won't last forever. As a small guy, you just enjoy the ride.

    Free carbonite style backup?

    Even many of the paid services don't work vey well (flaky automatic backup and synchronization, or uses too many system resources, etc) . I use Safecopy, 3GB free or pay for 200GB, and I am very happy with it.

    Wash Sales in 2012 -- Trading 1 stock only

    Simply put, the broker is doing it wrong, just showing "potential" wash sales. Search for the Robert Green article about this. I don't know of any broker who does it right. With only 1 stock, maybe you can do it manually, or else you need software like tradelog to calculate your real tax liability.

    Win7 Clock Drift 1sec / 10 mins - normal? fix?

    I think NISTtime just corrects the clock once. You need NTP which runs as a service, predicts the drift to constantly and smoothly adjust the clock. You can disable Windows time in services - Start -> Run -> services.msc

    Win7 Clock Drift 1sec / 10 mins - normal? fix?

    Yes this is true, the clock will have worse drift when a Java app is running. But a real NTP service can still do a pretty good job of correcting it.

    Win7 Clock Drift 1sec / 10 mins - normal? fix?

    Windows clock correction isn't smooth enough. Disable Windows Time Service and install Meinberg NTP, which will "slew" the clock instead of time stepping.

    Backtesting of HFT strategy - Limit Orders

    You improve your odds, but this is mostly another HFT myth. For example, if you join the bid or the ask at light speed, it is guaranteed that you are not first in line. ** 90% of attempts at HFT lose! They just lose! **

    Backtesting of HFT strategy - Limit Orders

    yes trade-through works ok. If you want to get fancier, you can think about these 3 cases: You placed a limit order that joined the inside bid/ask You placed a limit order that is inside the inside bid/ask You placed a limit order that is outside the inside bid/ask Good luck.

    First you post a "live leak" that is actually from late 2010 Then you post an article from defense.pk which sources from eutimes.com which sources from whatdoesitmean.com, a site famous for making things up. Move to politics & religion, this is one for the sheeple.

    For Superfast Stock Traders, a Way to Jump Ahead in Line

    So looks like you might get queue jumped if you direct your order and don't allow it to be routed out ... certainly not default behavior. Who does that? Rebate traders? Also, it only happens in a locked market. Isn't the only way to do that, to have two non-routable orders on different...

    Amazon AWS vs VPS: MetaTrader 4

    Amazon AWS is very reliable, but in the past has had some downtime - nothing is perfect. In my experience with AWS you are pinging from Virginia, around 10-20ms to NY. A good VPS can get you better pings and be as reliable, or even more reliable, than AWS. On the other hand, a bad VPS...
