Marketcetera Announces Major Upgrade to World’s Leading Open Source Trading Platform

 

 

 

Latest release of automated trading platform bolsters scalability and data segregation by user role, improves real-time P/L reporting

 

NEW YORK, NY & SAN FRANCISCO, CA - May 18, 2009, Marketcetera, the leader in open source platforms for automated trading, today announced immediate availability of the latest release of its popular automated trading platform, with four major new features to help traders scale, support multiple users and get deeper real-time reporting on profit and loss for intra-day positions.

 

Data volumes are exploding on Wall Street, with analysts forecasting equity options volume, for example, doubling annually in 2009 and 2010, and in return driving increased demand for automated trading platforms to help manage the volume. A recent survey by the TABB Group, a financial services market research firm, shows nearly half of the buy side considering a change in execution management system (EMS) this year, citing a desire to consolidate, integrate, customize, improve technology and lower costs.

 

"With market data volumes exploding, automated trading is becoming more prevalent on the buy side and across more asset classes, not just equities," said Graham Miller, CEO of Marketcetera. "This environment places tremendous pressure on investment firms to continue to make fast, intelligent trading decisions at ever lower costs per transaction. With the release of Marketcetera Version 1.5 and the benefits of our open architecture and powerful strategy research and development environment, we're fundamentally changing how traders can successfully meet these new challenges."

           

The Marketcetera Trading Platform's open and modular architecture designed to facilitate rapid deployment and ease of extension. Rich APIs including a built-in scripting engine, make it easy to extend the functionality of the Marketcetera Platform. Internal teams can develop custom pricing and risk modules quickly. Complex new trading strategies can be tested and implemented in minutes. And a foundation of open source technologies such as QuickFIX and Esper provide the performance of proprietary packages with the flexibility of a custom solution.

 

The major added new features in Marketcetera Platform Version 1.5 include:

 

  1. Real-time intraday position and profit and loss monitoring. The Marketcetera Platform desktop application, Strategy Studio, now supports real-time intraday position and profit and loss tracking and management on all trades around the clock.

 

  1. Simplicity and security for multi-user installations. Building on the existing authentication framework, the Marketcetera Platform now provides segregation of trading activities and strategies for traders and supervisors or risk managers.

 

  1. Level 2 and depth-of-book market data. Get more than just the best bid and offer. With added support for NASDAQ Level 2, TotalView and other depth-of-book market data feeds, Strategy Studio and strategy APIs allow liquidity seekers all the information in the marketplace.

 

  1. Strategy Studio - strategy agent integration. Now the Marketcetera Platform allows traders to directly deploy strategies on remote servers. Traders can manage multiple agents through Strategy Studio that may be running on multiple servers, offering new levels of trading scalability and control.

Make Ajax much faster with Tomcat Non-Blocking I/O (NIO) in its Advanced IO modules

Using Non-Blocking I/O (NIO) improves server performance drastically because of its efficient use of system resources (threads). The gain in performance is very noticeable in Ajax applications. It also lets you control system-resource usage on a server under pressure. This article explains how to optimize your server for performance during the handling of both Ajax and regular requests.

Linux Distros Are Like Lays Potato Chips...

... You Can't Have Just One!

Multi-booting - My Way

I've been multi-booting since I first came to Linux. Originally, it was due to my transition from MS Windows to GNU/Linux. Later, it was because I wanted to try more distributions. I was still hunting for the one that "fit" me best. I've since found that distro (Slackware). However, I still have multiple operating systems on my computer for varying reasons.

 <>

My current hard drive partition and usage map looks like this:

SATA 1 - Main/Secondary OS + Linux Archive

Primary - 25Gig: /(root) - Slackware................../dev/sda1 (ext3)

Primary - 50Gig: /home - Slackware..................../dev/sda2 (ext3)

Extended - 175Gig:..................................../dev/sda3
Partition - 25Gig: /(root) - Debian.........../dev/sda5 (ext3)
Partition - 50Gig: /home - Debian............./dev/sda6 (ext3)

Partition - 2Gig: /swap (common)............../dev/sda7 (swap)

Partition - 98Gig: Linux Archive............../dev/sda8 (ext2)


SATA 2 - MS Windows + Experimental Operating Systems

 These three drives add up to three quarters of a Terabyte of space... way more than I actually need. However, space is cheap these days. I still remember paying $100 for a 10Gig drive less than ten years ago. Previously, SATA 1 and 2 were in RAID 1 (mirrored) configuration with MS Win XP Pro on them. What a waste. I rarely ever boot that OS these days (games only), so a broke the RAID down and repartitioned/reinstalled everything on my system.

The ten partitions you see on the SATA 2 drive are my experimental Linux slots. When this partition map was made, I intended to put CentOS, Arch, and Ark back on them, with the last two saved for Gentoo and maybe FreeBSD. I haven't gotten around to installing them yet, though. 

A few things to take note of when partitioning and multi-booting in this fashion:

1) Remember the SATA 15 partition limit. Many newer distros use the libATA kernel drivers which force drive recognition as SATA regardless of whether the drive is EIDE or SATA, so for this reason remember to place your /common partitions and /swap partitions on the lower numbered ones. A libATA distro installed anywhere else on the lower 15 partitions (or another drive) will still be able to "see" and mount them this way.

2) MS Windows is like the "Borg" when it comes to being installed on a computer with other operating systems. It seeks out and "destroys" other operating systems. Be sure to install MS Windows first. It needs to be on the first partition of whatever drive you're installing it on. After which, you can install your GNU/Linux distros safely.

3) Install your MBR controlling distribution last, time-wise, regardless of which partition/drive you're installing on. This will allow it, especially in the case of Debian's excellent GRUB, to "see" all the other installations and write them into your menu.lst for you. Even though Slackware is my primary operating system, and since I don't use LILO, I allow Debian to control the MBR and boot my system with its GRUB.

4) Lastly, as in the case above, if your MS Windows installation is on a different drive than your MBR controlling OS, then your BIOS may have troubles booting the correct drive. No matter what you choose in BIOS as the first device, the Windows drive will boot. The reason for this is that Windows installs a bootable flag on its own drive. This flag gets priority from the BIOS. To set a bootable flag on the drive that you want to boot will require a bit of manipulation using a Live Linux CD* and the fdisk command.

Boot your Live CD and start it. From a terminal session within the CD do the following:

 # fdisk /dev/

fdisk> a (option to toggle bootable flag on drive

--partition number? 1 (first partition on the drive)

fdisk> w (command to write the new info to disk and exit fdisk)

--bootable flag reset for this drive

This will set the bootable flag to the drive you choose. Reboot, go into BIOS setup and choose your first boot drive. It should boot fine now.

 *Another option to use is the way I actually did it on my own system... I used SLAX on a flash drive to perform the fdisk above. Worked like a champ!

Anyway, that's the way my system is set up. Whenever I add or change operating systems, I just edit the Debian /boot/grub/menu.lst to reflect those changes.

Have fun with it!

 Until next time...

Problem with LAN MOUNTS

It seems the only major difficulty that still exists for me in swapping from WIN to LINUX is the management of PERMISSIONS!!

 For me it is a convoluted hit and miss affair ... and is continually proving a thorn in my side.

 The latest nightmare is trying to get the correct permission allocated to simply mounted network shares!! Why is it so difficult???

My WorkStation runs latest pclos 2009.1 KDE ... it contects to shares from two other machines .. one an XP 'fileserver' that holds all dynamic data files and the other is a LAMP server running under pclos 2007 GNOME ... my local LAMP host.

The XP Fileserver exposes SAMBA shares to the network ... the LAMP Server exposed NFS shares to the network.

These XP and LAMP shares are mounted on my PCLOS workstation via the Control Centre >> Network Sharing >> Configure NFS / Windows Shares

Here is the fstab file:
########################

The the directories under "/mnt", of course are owned by ROOT, but have been given 777 permissions by root prior to mounting.

The problem is that everytime a file is written to any of the mounted shares from my workstation [logged on as a USER, not ROOT] i get the message ...


"Could not change permissions for <filename>"


... for each file that is copied/moved to the mounted share, whether it the SAMBA or NFS share.

I think i understand the reason why .... it is because the Mount Points on my PCLOS client are owned by Root ... and while these Moutn Points have been given 777 permissions, it does not permit the permissions of the files to be altered by a user other than root, following transfer to their respective servers [Why is it trying to 'change permissions' anyway????]

I thought i would fix it by moving the mount points on my WorkStation to within the "/home/myusername" directory, and ensured that the Mount Points were Owned by me and my group!!!

Sounds logical *keh?* ...

HOWEVER, following remounting of the shares to these 'USER owned' mount points, the system forces a change of ownership of my Mount Points to that of ROOT!! ... and i find i am back in the same position as when the Mount Points where under "/mnt"!!

And, annoyingly, the problem persists!!

Any clues GURUS ... *smile*???

Thx Rfah

 

Searchable group discussions?

I've added few how-to in group discussions. Now I am trying to search if those posts can be searched from Linux.com search option, I am amazed to see that none of the discussion contents are searchable.

I am wondering.. what is the point of adding group discussions when its not searchable?

 

NOOB's adventure in Linux From Scratch

 Hello again,

This morning I find myself eating a bit of crow, instead of following the link provided on the LFS prerequisites page now embedded into memory,  I typed in the address to the Linux User's Guide  http://www.linuxhq.com/guides/LUG/index.html  and went immediately to a General Disclaimer page... this is not the case when you follow the link in the LFS site.. they send you to http://www.linuxhq.com/guides/LUG/guides.html  missing the Disclaimer page all together.

  So, it seems that the errors I was complaining about are already in the process of being repaired. 

  I've sent an email to the webmaster of the site,  apologizing for my mistake and informing him of how sites are linking directly to the guide and his pop up windows being skipped over.

  Just goes to show how the community works quickly to fix mistakes .. Bravo!!

 

Linux on Netbooks

It is so annoying (but not unexpected) that Microsoft swooped in and fixed it so you can't find a netbook with Linux on it in any store, but this is the icing on the cake:

http://popey.com/Asus_The_Fair_Weather_Friend

I was in Costco a couple of weeks ago and I was looking over the netbooks to see if there was one with Linux installed (of course there wasn't).  The salesman came up and asked if I had any questions.  I said "yes, where can I get a one of these with a decent operating system instead of Windows".

I can say that I won't ever buy another machine with Windoze pre-installed. I did that once and I have regretted it ever since. I tried to get my money back for the unused copy of Windoze that came with it, but finally gave up. I am mad at myself for giving up too easily, I should have fought the battle just on principle.

It occurred to me that we should grab the "itsbetterwithlinux.com" URL and put up a rebuttal, but it looks like somebody already has it. I certainly hope it isn't a Redmond lackey cybersquatting.
 

NOOB's adventures in Linux From Scratch

Back again,

 I'm about 3/4 of the way thru the first prerequisite . Feeling the first inkling of understanding of what it takes to put a command line together. Not just a  single command. 

   I personally don't think that the  http://www.linuxhq.com/guides/LUG/guide.html  could be the best one to learn from as it's somewhat dated and I the NOOB even find many mistakes ...  It for one is not easy to follow,  it jumps all over the place. Command examples  are not with the paragraph that  writes about it. They're  is sometimes three or four paragraphs away from it, with no direction or no# linking the example with the paragraph... confusing to say the least.  There are mis-spelled commands.  Easy for an established person to realize there's a problem here. But, I found myself lost on many occasions following along blindly lost as to why I wasn't getting the same answer at they get.. or getting an error about the command , only IRC and Google saved me.  None the less,  I'm committed to my goal of getting the knowledge I need to successfully build LFS. I'll finish reading and making notes, and follow up with google and other pages as needed. Actually, thats probably the reason I'll be more competent. I won't give up... I'm making everything work before I move on so the end result is more information is sticking to my brain because of the mistakes :) It is aggravating but that's exactly why I'm retaining more info ???

  I've been at this now about 3 weeks. I quickly read through the prerequisites only to fall flat on my face building LFS. I've really made the point of studying all the info pointed out in the prerequisites  this time...so that I will fully comprehend what I've read.  At this point in time , I believe that just the prerequisites will not be enough for me. We shall soon see.
