Try Udacity or Coursera. Both have online courses. There is a new course (they add a new lesson every few weeks) on Udacity called Introduction to Programming in Java https://www.udacity.com/course/cs046 Good luck, -David

Don't worry about the language. Most any language is more than fast enough unless you are running a modified linux kernel and drivers, the absolute fastest data and broker, co-located, and execution costs way less than a retail broker can provide. C++ is fine, but those who think it is faster...

With Intel's 50 and 60 core processors coming out this year, Tesla (I assume running on a GPU) will no longer even be a consideration for many. -David

Truer words were never spoken. P.S. Thanks for the laugh.

Excel is a good choice no matter what else you do. There are free data sources and XLQ (not free but reasonable) can help get data into Excel (there is probably free code to do this also). I'm sure there are tons of free tutorials on Excel. R is the next obvious choice. It is extremely...

Has anyone used "Shrink My Taxes", an accounting firm in Florida for setting up a LLC for trading? I saw some articles by them on Trading Pub. Just looking for some reviews of the various choices. Green seems to get pretty expensive and Traders Accounting seems to get some less than great...

Thanks, I will try to remember to post this information next year in November (and Keep it alive by replying). This is an incredibly simple solution and could save many from nasty surprises. Thanks, David

Is it true that closing all your positions and not trading during the month of December solves Wash Sales Rule tax problems? Thanks, David

I am considering trading an account for a relative via an IB "Friends and Family" account. I am fully automated day trading over a universe of about 2500 stocks. The problem is the "Wash Sales Rule". Is there anything they can do to avoid it? They work full time. Thanks

O(n) should be read as "On the Order of n" meaning that the time it takes to preform the lookup increases linearly with the number of items in the array. It there are 400 items in the array, it takes up to 400 times as long to find the item you are looking for if you are looping through every...

IQFeed comes in as a single stream. I look at each line and determine what kind of message it is. If it is a new tick message I get the symbol out of the string and pass the message to the queue for that symbol/system. I have a thread pool that takes the messages off the queues and passes the...

You are of course correct, IQFeed is not meant for polling historical data during market hours. I was just pointing out that you can stream tick data for up to 1800 symbols. Checking the documentation, it appears the tick stream includes fields for OHLCV. Since I don't use these fields I...

Actually IQ Feed has an 1800 symbol limit, you just pay more. I have my limit at 1300 symbols and I regularly watch 1000. If you need more than 1800 they have another (more expensive) product. -David

Sorry I wasn't clear. I am using OPG Market orders which are Market On Open orders. IB won't accept the order on some symbols like SPY. Thanks, David

I am trying to experiment with Market On Open orders in my IB paper trading account using TWS. I am getting a message "Warning: At the open order could not be executed" on symbols like SPY. SPY trades on the NYSE. Other symbols like AAPL trade on the NASDAQ and the order works fine. I use SMART...

I haven't noticed any problems with IQFeed. I use it every day. -David

The timestamp originates on the IQFeed server. David

I agree with ssrrkk. Java is definitely not a problem and I run TWS every day, all day, no problems. FireFox, I have given up on. -David

I use a old i7 (1.8GHz) laptop for trading. It is auto-trading with no charts. Watching every tick (IQFeed) for 1000 symbols takes about 14% of CPU usage (7% for DTN data component and 7% for my trading app running lots of calculations on each tick). Assuming you are running a well written...

>>Dude - get 2 UPS backups for your router & switch and computer. If your FIOS or CABLE is above ground, flatten your positions BEFORE the storm hits.<< Thanks sysWizard, I do have UPS on everything and a generator for the house though I don't have redundant internet. Just looking for the...
