MasterDATAlink Composite / Breadth Datafile Downloader
|
This letter should have been out over a week ago, but I decided to postpone its publication until ready to make an announcement promised in last month’s letter. As I stated in my last letter, “The program is written and fully functional and will be distributed after addition of a few more features and completion of the help files.” Well, that was true, I thought. In my enthusiasm, however, I neglected to heed the law of computer development time. There is “normal” time, where an hour is an hour, a day, a day, etc., and then there is time as measured by those working in the computer world, where is day is almost certainly equal to two, three or more “normal” days. An hour is almost certainly equal to the rest of the work day and perhaps well into the night. OK, I made my point. |

If something is difficult or cumbersome or a “pain” to some lower body part to do, eventually, in my experience, it will not be done, no matter how beneficial. Such was the recent structure for downloading the historical composite / breadth datafiles from the MasterDATA web site. In the past, subscribers had two options. Manually download a self-extracting zip file and go through the tedious process of unwinding it or visit the web site and manually download one file at a time. A surprisingly large number of subscribers were able to tolerate this daily task and, most definitely, there efforts are appreciated, and, I assume (hope), well rewarded. Trying to keep myself in the loop, I attempt, as best I can, to duplicate MasterDATA’s subscriber experience. I download every day just like them. It wasn’t long before this daily task slipped into the background. What would happen, I thought, if the entire process could be automated and completed entirely in the background? What if the datafiles were already there when subscribers wanted to do their work? |

We proudly announce MasterDATAlink. After a very simple configuration by subscribers, historical composite / breadth datafiles can be updated with a mouse click or two or, better yet, totally automated using Windows Task Scheduler. One, a few, or all 544 datafiles can be downloaded, ready and waiting for your analysis work. The program is highly configurable and can effortlessly download and update several different download lists throughout the trade day, all as scheduled by you (our daily datafiles are updated hourly throughout the trade session). |
|||
|
Its a two step process. First, when the market is closed, run a full download (generally, at least several hours after the U.S. market close or overnight, its your decision). This download retrieves the entire start to finish datafile for every MasterDATA compiled index and ETF. The reason for this is to insure that your historical data is as accurate as possible. These “full” downloads may take as long as a half hour (depending on your internet connection speed). This is normal and, because markets are closed, downloads are not really time sensitive. You should automate the process anyway, right? |
|||
|
Next, when markets are open for trading, run the updates you have configured. These updates occurring during the trade session generally take less than a minute for all datafiles and just a few seconds or less if you only want a select number of updated daily datafiles (again, depending on your internet connection speed). In other words, when time counts, update time is very minimal. |
|||
| I must admit, compared to the past, I love using this “little” downloader program. For more information about MasterDATAlink, visit the new MasterDATACSV.com web site. | |||

See the above…. |

|
With One Major Exception…. |
|||
|
Subscribers: Please start using the new MasterDATACSV.com web site and download, install, and use the new MasterDATAlink downloader program for retrieving and updating your .csv datafiles. The old web sites will be discontinued and zip files phased out at month end, March 31, 2007. |
|||
|
By the way, non-subscribers can download using the MasterDATAlink program also, but only the Dow Jones Industrial Average historical datafiles. Data will be current so they can get a truer picture of the value of the data. Forgive us, we do have to do some marketing. |
|||
|
Numerous enhancements, refinements, corrections and outright additions are now in place throughout the MasterDATA web sites. Visit our “Milestones” page for more information. |

The past few years of compiling, providing and delivering composite / breadth data have definitely been a learning experience. Although as much forethought as possible is given before committing to any particular structure, without exception, real time experience quickly shows you the error in your ways. Experience is the best teacher. Certainly, we now see how we can do better. The following overviews our immediate game plan for significantly upgrading overall service to subscribers. |
|||
|
Consolidation Of Products and Services |
|||
|
No, We Have Not Forgotten MetaStock Subscribers |
|||
|
So why change anything? Efficiency. By consolidating our plug-ins into one, further development for one user will benefit all users. Ultimately, we save time which facilitates even further development. Additionally, subscribers using our composite / breadth datafiles in Metastock will generate their own MetaStock format price files from their downloaded datafiles (this will be a built in function of the MasterDATAlink program). Automatically generating MetaStock format (.dat) price files on your end will save significant download time and processing and publishing time (on our end). |
|||
|
When we make a program or datafile change, one of our highest priorities will always be to provide the smoothest transition path possible for all subscribers. |
|||
|
Monthly Letters To Subscribers |
|||
|
There is one further and important continuing commitment to you. Letters will not be solicitations to buy or subscribe to anything. Subscribers will be informed of new services, but we will make every effort to stick to the facts without any hype. Finally, if you would rather not receive our monthly letter, a link will be provided at the bottom of each (including this one) to easily remove yourself from future mailings. |
|||
|
MasterDATA will never share or sell your email address, period. Even if we have associations, affiliates, partners or any other kind of relationship, the only email you will ever receive as a result of subscribing to anything MasterDATA offers will be an email directly from MasterDATA. We have all been sucked in by some seemingly reputable internet service or product that then distributed our email address to what seemed like every junk mailer on the web. That will never happen here. |

| Composite data is the basis for many powerful trading tools. It is my job to provide it to you in such a way that nothing gets in the way of your using it. Comments, criticisms and suggestions are always appreciated. I thank you for your past support and hope you continue with us. In any event, good trading.
Best, L.P. Carhartt
