includes stock market facts, daily motivational quotes, and calendar-based rules such as the January Barometer As a seasonal indicator, I think the January Barometer still shines brightly, Jeffrey Hirsch says It s an indication of what the climate is for that year, he says, just one of many things you look at What if January is negative If you re a long-term investor, Hirsch says, you d want to be more cautious about making new purchases Consider taking profits on rallies If you re a short-term trader, you could implement hedge strategies or go short You could also sell covered calls Jeffrey Hirsch admits that although the January Barometer is useful, sometimes it doesn t work There are times when the January Barometer has been less indicative, so you always have to consider other indicators before making a move into or out of the market A well-known calendar-based saying that has also been reliable is summarized by the old Wall Street adage, Sell in May and go away According to Hirsch, you should be invested in stocks between November 1 and April 30, and then switch to fixed income for the other six months This has produced reliable returns with reduced risk since 1950, Hirsch says He explains that people s behavior and what they do with their money and time affects the economy and the stock market This creates seasonal and other recurring patterns in the market But nothing works all the time, he cautions, so you have to be attuned to current events and market conditions when using calendar indicators Don t be the last bear or last bull standing Let history guide you, be contrary to the crowd, and let the tape tell you when to act For example, for years you couldn t go wrong if you followed an obscure indicator called the September Reverse Barometer The theory: if the market was down in September, you d invest after the September harvest when farmers invested their paychecks in the stock market However, as people switched from working on farms to living in the city, the indicator permanently stopped working Therefore, if you do use calendar-based indicators, it s essential that you also consider technical and fundamental indicators before making big bets based on their results In addition, pay close attention to how the market performs in January Mark your calendar now.

Each data flow has a few properties that should be evaluated for each implementation. DefaultBufferMaxRows and DefaultBufferSize are two properties that can drastically increase data flow performance if adjusted correctly. DefaultBufferMaxRows specifies the maximum number of rows SSIS will place in a buffer. DefaultBufferSize specifies the default buffer size that SSIS uses in its calculations to determine how many rows to place in a buffer. The maximum allowable buffer size is 100 megabytes. Tuning these two parameters will ensure that your data flow is optimized for its specific dataset. To determine the optimum setting, turn on the custom data flow

Your choices on this are somewhat constrained, because the commands for specifying where to put the worksheet don t always work as they should The parameters at beginning of and at end of work, but the parameters at before and at after don t work reliably Because the default placement is at the beginning of the workbook, there s little point in adding at beginning of unless you need to be explicit so at end of is the parameter you re most likely to need For example, the following statement adds a new worksheet named 2015 Planning to the end of the Budget Strategyxlsx workbook:

Summary

.

make new worksheet at end of workbook "Budget Strategyxlsx" with properties {name:"2015 Planning"}

logging event BufferSizeTuning. This event, when reading the resulting log file, will tell you how many rows were placed in the buffer. If your DefaultBufferMaxRows is set to the default of 10,000, and the BufferSizeTuning logging event is reporting only 2,000 rows were placed in the buffer, you ll need to increase the DefaultBufferSize property to accommodate more rows or reduce the size of each row by eliminating unnecessary columns. If your data flow has BLOB data in it, specifying a folder in the BLOBTempStoragePath property will allow you to change where BLOB data is spooled out to disk. Choosing a faster disk, instead of the disk specified in the TMP/TEMP environment variables, you may be able to increase data flow performance when working with BLOB data.

SSIS always spools BLOB data to disk. Ensure that BLOBTempStoragePath is set to a disk that s large enough to handle your BLOB data.
