abooz, Since you seem new to options, I'm going to answer your question directly rather than commenting on what I think of AMZN. You need to pick a put's expiration date and strike price. The strike price is the price you believe AMZN will go below and the expiration date is the date that this...

I guess another way of looking at it is why do you think D isn't true? What do you think is correct? What do you think the values of a[3], b[0][2], a[2], and b[2][1] are? Since you specifically mentioned octal in the subject, my suspicion is that you are aware that: a[2] is 053 b[2][1] is 43 If...

Maybe a dumb question, but is it possible to set up multiple brokers with the same account at a clearing firm or some other method to achieve the following? Lets say you have an open position at broker Z and for whatever reason you can't close a position at broker Z (generic routing issue to...

To add to that -- microwave towers have their locations chosen to provide a straighter (ie shorter) path and subsequently a lower total distance to travel than fiber. Even if right of ways and logistical issues of the path of buried or hung cable isn't a problem, you still have to deal with the...

He means a radio (microwave) link between Aurora and NY4/5 -- not the public internet.

If the idea is patentable then you either: 1) get them to sign an agreement that they won't steal the idea BEFORE you tell it to them. This is going to be difficult. People who have ideas thrown at them and are in the innovation game don't want to sign agreements like that because you may have...

Is it possible you were looking at the bid/ask only at a specific exchange rather than the NBBO? If that was not the case, then I suspect the other players who took your trades simply determined that the actual spread could have been smaller, but with no competing bids/asks there was no...

It is indeed a noble cause. You could probably get KCG, Citadel, or similar firm that pays for order flow to provide funding for such education in your school. After all, they need more blood to feast upon educated market participants. ;)

Take NASDAQ as an example. At a particular price, the queue is not strictly FIFO. Whether an order is display or non-display will cause it to jump ahead or fall behind other orders in the queue (non-display is lower priority than display). A newer order type, extended life, will have a higher...

I'm not familiar with their platform -- do you pay for the news feed or is it included for "free"? If free, perhaps they have an agreement with their news provider to get a lower cost (to them) feed in exchange for omitting the symbol data.

Based on the way you worded that, it makes me think you have confused puts and calls. The put allows the person you sold that to to sell the stock to you for $16/share. If the price were trading at say $20/share, the put option would be out of the money and the person holding the option would be...

I want to start by saying I have not subscribed to this value bundle you're referencing, so what I'm saying is based on the description of it. The value bundle you listed specifically says it is the aggregated quote, trade, and volume for the 4 BATS exchanges. It does not say for all exchanges...

If you are looking for aggregated trade/volume data, then you probably want to look at the Network A, Network B, and Network C subscriptions (they're $1.50 each). These are the consolidated tapes (CTA) for NYSE, AMEX, and NASDAQ listed securities respectively.

Good luck finding a competent developer who isn't going to laugh at $50/hr. If that's your salary offer, I can only imagine how awful the profit sharing offer would be. I have no doubt you'll find someone to take your offer, but you get what you pay for and competent devs know they're worth far...

Ask them what they do for a living. Depending on their answer, I think an effective response would be to then ask if they'll teach you to do whatever they do and set up a company to compete with them -- free of charge of course. ;)

Even if the platform is using tick data, if it's not basing the graphs on the exchange time stamp, it will still differ. I can't speak to MT4 specifically. I would assume that if it's using tick data that it is also using the exchange time stamp, but I can't guarantee you that.

The short answer to your question is "it depends". It depends primarily on the following: 1) is the data tick by tick or is it consolidated at some increment (ie 2x per second)? 2) does it include the exchange time stamp? 3) does the platform utilize the exchange time stamp or some other time...

Got it. Thanks.

In the top row of numbers in the screenshot you have TT latency of 46us and Exch latency of 198us. The Exch latency is the time between when data is sent from the exchange until TT receives it, then the TT latency is how long it takes TT to respond, then we should expect another exchange latency...

Of course it's also possible the market is being overly optimistic and even if SGI earnings are good that it won't be good enough and you'll see a drop. Or perhaps the problems CRAY is having are going to be good for SGI in over the next year. ;)
