I am still using front-end applications (like Sterling, Lightspeed, etc.) to make money, but I want to push into exchange colocation and make incremental strides towards achieving an HFT infrastructure. The market-data side is straight-forward. It's the order-placement and associated...

What did the equity curve look like during your out-of-sample tests?

It all depends on your style. If you don't have a style yet, the prop firm's value is in being able to sit next to people who know how to make money (if there are any at a given firm.) If you don't see anyone making money at a prop firm day in day out and putting up multiple green weeks...

Did you die?

What sort of trading strategies do retail traders who are profitable tend to employ? I just get the feeling most are just spreaders or long/short basket traders. For momentum type trades the retail slippage/execution quality is just so poor these days.

I have no position. You're all crazy. :-)

Thanks for the tip. I was not aware of this.

I'm taking the rest of the year off myself. The risk:reward ratio makes no sense, because any of my positions will get blasted by insiders who have eyes and ears in DC and know which way the vote is headed or which way the wind is blowing. I'm really fed up with this strangle hold DC has on...

The occasional beating can be disastrous, though. For me, a "beating" event can cost 4-5 days (possibly even more) of earnings. It's true the algorithm can detect abnormal volume, but the real issue is when you have a passive element to your strategies and are not HFT. Or, for that matter, if...

Not interested in profit. I'm interested in limiting damage. I tend to make money when the market is operating "as usual" and not when there is news blowing things apart. I'd rather have the algo turn off than detect some false signal on account of news.

I don't normally care about what is going on on CNBC, but what she did was totally unprofessional and I am not a fan of Cardin.

Do any of you guys use news service inputs into your system? I'm currently manually using theflyonthewall.com. It's generally lagged a few minutes from when the true news is released, but it's not bad. Are there any services that are more API friendly and within the price range of a...

I like intradaybill's posts, maverick74, d08, sellindexvol666, and njrookie1's posts. My favorite poster of all time, and a troll poster, was st0cktr4d3r or whatever. I laughed for hours at his threads.

I believe you. I'm a stock trader, but I got into the game late. I always feel like everyone in our business who just sits on their butt (and collects a check from everyone else's work) all got their easy money in the 90s, had the sense to go buy HFT hardware, and milked that into today's...

I think anyone smart enough to get hired on Wall St. generally has the potential to be a decent (or maybe even excellent) programmer. However, code quality is a function of more than just the programmer. The culture makes a difference. I've been a solo operation for a while. I harbor a lot...

You're the man, 2rosy. Thanks.

Are there any open source projects that have simple matching engines that accept FIX tags? I want to build a simulation engine to accept and respond to simple orders for a fake asset class (let's call it "The Widget"). I want the matching engine to have two modes, a kind of "pure" mode where...

If you're holding for 30 days, I strongly, strongly, strongly recommend either buying options for protection on position or using a hedged long/short portfolio. I had a short position in 2008 on which I gained 10% initially but ended up losing 50% because I couldn't get out because of the 30...

Good post, oldtime.

I don't think the quality is poor because of lack of talent. I think the quality is poor because management doesn't care that much about quality or doesn't care about it all of the time. Business decisions override performance and quality decisions all the time. And I'm not saying this...
