If your stops are limit orders, then they can get blown through without execution. If your stops are market orders then your limit trigger price can be quite distant from your fill price. You need to do some serious thinking about your risk

Exactly. The vast majority of "exotic" order types fall into generally two categories: 1) Orders that help deal with the asynchronous nature of the market. Removing the restriction on locked markets can reduce the need for these o

There are plenty of regular old software engineers in the industry. You don't have to be a math genius or a finance oriented guy. Doesn't mean you'll be trading or working directly with quants, but the amount of code required

Make does not do this directly. Typically you generate a set of dependencies using gcc. gcc can be told to output a rule suitable for use in make that describes the dependencies of a source file. See the -M option and friends.

Give me a break. The guy was most certainly not an independent thinker. Nor was he a critical thinker. Nor did he have any respect for the challenge he was taking on. He was an angst ridden teenage boy captured in an twenty something's

Relative timestamps between venues don't matter. More importantly, using timestamps without a common reference point makes it impossible to assert what happened first, because the absolute value of the timestamp does not matter. What matter

by lrm242 14y ago
The most likely explanation: no one got anything early. Venue timestamps can often disagree by a significant amount. It is very likely that SIAC (distributors of CQS and CTS) simply are not well synced to the reference clocked used to distr

Diabetics have to manage insulin levels. They manage their carb intake because of this. It has nothing to do with managing their weight. With respect to obesity you might consider what you just said: carbs are abundant and cheap. Therefore,

Exactly. Few people understand what their calorie budget is and have no way to relate their intact decisions to that budget. Losing weight is simple: eat less than what your body needs to maintain itself. In doing so your body will pull fro

Calories are the only determinant as to whether you gain or lose weight. It's thermodynamics. 3500 calories deficit or surplus is approximately equal to 1 lb of body weight lost or gained. Your body burns X calories per day to feed itself.

This is a great little game. Just played a few rounds and had a blast but hit some nasty lag a few times. The basic game play is quite addictive. Nice job.

They don't dress that way all the time. From what I've gathered they have "Formal Fridays". At first when I saw Notch mention this on Twitter I was a bit confused, but now I see it goes nicely with the theme of their office.

Each game likely used a fresh, unopened deck of cards. If each deck is non-shuffled then each time a fresh deck is opened you will see the same cards in the same order. Assuming the casino arranged for their vendor to pre-shuffle the decks

You don't like high message rates because it makes your job harder. You guys are a great data provider (I used to be a customer) and you're doing a pretty good job (if not somewhat biased, perhaps unconsciously so) of informing folks about

There is no need to guess the midpoint. The midpoint is simply: (best_bid + best_ask) / 2.
115.
by lrm242 14y ago
There is confusing terminology amongst venues. The key points are: you can execute at the midpoint or at any discretionary offset from the primary or market.

I think if you consult the literature you'll find that the prevailing trend is for markets to become more continuous rather than more discrete. Continuous markets help with true price discovery. Our markets are continuous in time right now

by lrm242 14y ago
That's correct. They display at a whole penny price but execute at the midpoint. They may also execute at an offset for the market or primary.

Midpoint orders exist on all the venues. All but EDGA/EDGX provide some rebate for resting a midpoint order. DirectEdge charges both sides for what they refer to as "midpoint match".
119.
by lrm242 14y ago
They are only accepted at the midpoint. EDIT: It's just a feature of the matching engine. It's not really that complicated. The venue, let's say BZX, accepts an order from you to display a BID for 100 at 20.01 and you flag the order and tel

An expected and uneducated statement. It's simple really: any participant who rests an order on the book is adding liquidity. Period. Many HFT strategies are largely passive (market making, for example) and therefore entirely rely on restin
