90% of big traders just lose? They just lose? Nobody wins in this world, except emg.

Along the lines of 'ODB' (the C++ ORM system from CodeSynthesis), are there any utilities that can, say, preprocess a structure or class description and generate a GUI widget that allows for automatic generation of either a table or a form that allows for manipulation of a widget? The purpose...

Tattoo material.

I don't want to spend $700/month just to be able to see the NasdaqBX inside quote. At that point it makes just as much sense to just use my broker API, however awkward an API it may be.

I was reading this thread and didn't manage to find an answer: http://www.elitetrader.com/vb/showthread.php?threadid=184302 The author is correct in that the feeds he is using do not have full book quotes, and I find myself in the same predicament. Is there any way to get this data...

Do any of you have any preferred/favorite apps for synchronizing the clock? I'd be thrilled if I could get as close as possible to the exchange (NASDAQ) clock, but would settle for an accuracy of around even 200ms or worse. Note that I am not colocated. This is for retail trading purposes...

Everything you say is true, but shouldn't the intraday correlations between each other be higher in the absence of news -- at least until the market digests news of non-sense? I mean if the futures go up, all bad news considered, the true price of the stock of a miner should go up in all cases...

Growth, maybe. Copper supposedly depends on growth in the economy in general. If copper miners are to be valuable, someone has to forecast substantial demand. Precious metals seem like a different story because those metals have very different markets. But let's consider copper miners for...

Can you elaborate on this point further and provide an example? The reason I'm asking is because, let's say I see someone trade out EDGA. It doesn't help me to go hit NASDAQ just because I saw someone trade out EDGA. That alone is not reason to go running off to an exchange where the remove...

I never had the cost structure to facilitate this sort of trading, but I wanted to investigate this style of trading so I designed some models around speed to understand my counterparties and spent a lot of time obtaining that speed to prove my ideas. What I found was that I was slowly losing...

I suppose I'll pre-order my yacht. What are the stated theories among people who have a clue for such wide discrepancies? (I, unfortunately, am not a member of this group.) I know that some miners have had hedges in place against future production, but shouldn't intraday movements in miners...

I've been watching the copper and gold futures vs. FCX and SCCO, and occasionally I see these stock prices just completely ignore the metal prices. I was trying to explain why this was happening by flipping through stock indexes, related stocks, etc, but couldn't find a reason. There were no...

I had a short-term edge that pulled around 85% accuracy briefly while I ran it, but generally my edges drop to around the 55% mark as well (on the whole.) The biggest dragons I fight are the fees and the bid-ask spread. Even if I design something with 80% accuracy, the fees associated with...

I am convinced that the internalization game is so critical that no market making operation out there can sustain long term success without securing their own source of retail flow. The public exchanges are so efficient that extracting a profit is like squeezing blood out of a rock, unless you...

I tried this. The only thing I didn't really like about this approach is the parameterization of the model that I used. The shifts in volatility can break the model, so engineering the model was 30% of the effort, and then dealing with all the various breakdowns was 70% of the effort. I've...

Perhaps I should've phrased it better. What are the general variables they look at when they are modeling whether or not to hold a given piece of inventory without deciding to delta hedge?

My understanding is that it used to be the case that options market makers would hedge their delta almost immediately whenever they got hit on the market. If they no longer do this immediately, then what sort of calculations are involved in terms of determining how long to hold the contracts...

In terms of definitions of "adverse": If the market is 3 x 4, and I see a limit fill on 4, I consider that fill adverse if the next market is 4 x 5 without any opportunity to see an exit on 3 for a spread extraction, and really adverse if it goes to 5 with no chance to get a reversion+rebate...

This is what I also believe; that the "true spread" in the market maker's mind is something different than what the true market is actually quoting (i.e., he quotes 3 x 5 when market is 4 x 5), and that he wants to get his fills where he thinks the true bid-ask spread should be. However...

Market makers can't jump the queue on NASDAQ (as far as I know); however, your answer hints at the fact that someone trying to be a market maker on NASDAQ may only be parking orders there to get a rebate exit on the other side of their position in hopes of extracting an inefficient fill or a...
