| | | MasterDATA Composite Plug-in Overview |
|
| | The MasterDATA Composite Plug-in allows MetaStock to automatically and seamlessly use MasterDATA's historical composite breadth, .csv format datafiles with no import or conversion of data. | | | Previous to the MasterDATA plug-ins, MetaStock was limited to MetaStock format price files only. MetaStock format price files allow only six data fields, open, high, low, close, volume and open interest (oi). Not only are the number of data fields limited, but users are required to use the names Open, High, Low, Close, Vol, and OI when referring to the data no matter what the data actually represents. If the field value is actually advances, you must reference it by one of these six names (depending on which of the six fields you place it in). Imagine trying to recall that "high" really means advances. Recalling such a name substitution next week is challenging. Next year, it is most likely nearly impossible. All in all, this arrangement is very limiting, very confusing and getting your data into the format often very time consuming. | | The MasterDATA Composite Plug-in allows real and meaningful names in your formulas. The plug-in currently reads any of 68 columns of data from our downloadable composite breadth datafiles. Data can be called for an issue representing the MetaStock function's "base" security as well as a designated issue and/or designated data period. Seeing "advances" in a MasterDATA Composite Plug-in formula will always mean advances. Here is an example of various MetaStock formulas using the MetaStock function's "base" security: | | | | ExtFml( "md.BySym", advances) | | | Or by a specific symbol: | | | | ExtFml( "md.ByFile", SPY, advances, BASE) | | | Or by a specific data period (Weekly): | | | | ExtFml( "md.ByFile", BASE, advances, W) | | | Or by a specific symbol and specific data period: | | | | ExtFml( "md.ByFile", SPY, advances, W) | | | How these formulas are constructed and used is detailed both here on the web site in the MasterDATA Composite Plug-in Configuration module overview section as well as within the installed MasterDATA Composite Plug-in Configuration program itself. Additionally, both locations also include the formula builders, md.bysym formula builder and md.byfile formula builder which make writing your plug-in MetaStock formulas easy and failproof. | | | The MasterDATA Composite Plug-in operates exactly like our MetaStockCSV Plug-in. They are actually both the same program. The MasterDATA Composite Plug-in however is specifically configured for our historical composite breadth datafiles. The MetaStockCSV plug-in allows you to use your own .csv format datafiles directly in MetaStock. Both plug-ins may be installed and used in MetaStock simultaneously. | | |
