    Ending the Deficit

    LOL wow somebody actually followed history. People forget why the Fed and such were created. It is not because people wanted power. It is because the United States constantly went bankrupt.

    This is what happens when the federal reserve prints trillions and trillions of dollar$$$$$$$

    Actually there is because it does have industrial use, and people use it as shiny jewelry to adorn themselves. So how does one wear a NFT of a rock? :rolleyes:

    How can I protect my own trading system's source code (C#)

    Having worked at an investment bank and hedge fund it is largely about trust and a really nasty work contract. However, if you are concerned there is a really simple solution. Put it in the cloud and lock down permissions. I know that Amazon EC2 is a full blown Windows Server instance and...

    IB's accrued interest

    The beauty of IB is that it both gives and takes Libor. So count yourself lucky that you have such a good broker. You can do a carry trade, which is impossible with any other retail broker. Now about managing forex positions... What you need to understand is the following. Imagine you...

    Programming language to learn for automated trading?

    The problem with your question is that it presupposes the platform. What you first need to decide is which platform you will be using... Is it IB? Is it Tradestation? Is it NT? The platform then dictates which programming languages you can use. I happen to use IB and C#.

    HDF5 Layout for Multiple Stocks

    Map-Reduce at first I thought was a really difficult topic, but then as I dug into it what I liked is that it was a clean way to interact with data to set it up in different ways. You have your data in format X. But when data mining you want your format Y, which have if's and the likes in it...

    HDF5 Layout for Multiple Stocks

    Actually I did answer the question in the first response. You receive the data into memory as raw data or very simple structure. You need enough ram to keep a days worth of data. I use run two servers for pure data collection. Then you need another server or servers to persist the data...

    HDF5 Layout for Multiple Stocks

    Yes SQL gives all of this automatically and quite frankly I would rather spend my time writing code solving my trading issues than writing code to keep my program running. Now about backing up a SQL database, I don't back up to a file. I use the NoSQL approach and just replicate the data to...

    HDF5 Layout for Multiple Stocks

    SQL databases have procedures that allow me to do fail over, master slave, redundancy! When I backup a SQL database or a NoSQL database I don't actually backup files, I backup data... Files on the other hand need to be copied, checked for consistency. And if you move from one platform to...

    HDF5 Layout for Multiple Stocks

    I have gone through many different variations (files, databases, etc). The answer IMO is to use relational databases, but in very specific ways. For example when receiving ticks I don't process I just write to the database, and keep enough of them in memory as needed for processing. For...

    Java vs C++ or C#

    I am not going to debate that abstraction, object orientation, and bad design add's overhead. It does. However to say that Java, C#, and Scala (which is Java) are bloated is actually incorrect. The problem with the typical compilers is that they only do a generic optimization. Even with...

    Java vs C++ or C#

    Or Interactive Brokers... Think or Swim is considered a dog by some. However I always thought IB's TWS was pretty quick.

    Java vs C++ or C#

    I did not want to say that as an argument... But yeah I agree with you. I am so much more productive with C#, or Java.
