Create
a Custom Indicator Using the "csv.ByFile"
Plug-in Formula - Example 3
Using the "csv.ByFile" (3
parameters) formula builder, this section takes you through
the step by step process of creating a MetaStock Custom Indicator
somewhat less specific than Example 1. This indicator
will retrieve one statistical data series from the MasterDATA
composite / breadth datafiles, for a specific symbol and the
MetaStock function base symbol's data period. The specified
symbol will remain unchanged in any
MetaStock function in which it is used while the data value
will reflect the base symbol's data period.
Click on
,MetaStock's
Indicator Builder. The "Indicator Builder" dialog
window opens.
Click on the "New" button. The
"Indicator Editor" dialog window opens. Leave this
dialog window open.
Below is a working copy of the MetaStockCSV
Plug-in "md.ByFile Formula Builder" discussed previously. Using
this formula builder, make a new formula that retrieves the
composite statistic, "Total components advancing"
for the S & P 500 Index (.SPX) for the
base symbol's data period.
In the section, "Select an Item in each category:", click on the drop down
box "Select Index or ETF" and click on the symbol desired,
in this case "$SPX - S&P 500 Index".
Again, in the same section, "Select an Item in each category:", click on the drop down
box "Select Composite Statistic" and click on the desired
statistic, in this case "Total components advancing".
Finally, in the same section, "Select an Item in each category:", click on the drop down
box "Select Data Period" and click on "Use
the base data period of the current Metastock function".
Then click
on the button "Click Here To Make the Formula".
Your new formula will appear in the subsequent "MetaStockCSV
Plug-in Formula"
section.
Click on the button "Click To Copy the Formula To Your
Clipboard".
Click in "Formula" field of the
MetaStock "Indicator Editor" dialog window you previously
opened in step two above. Paste your new formula in this
"Formula" field by holding down the "CTRL" key and
pressing the "v" key.
Type a "name" for your new indicator, such as
"SPX Advances".
Your finished custom indicator should appear as follows:
This custom indicator will retrieve the
"Total Advancing Issues" statistic for the
S & P 500 Index (.SPX) for the MetaStock
function's base data period no
matter what MetaStock function it is used in.
In the interest of keeping yourself
organized, you might consider placing an identifying
punctuation mark or letter at the beginning of your own custom
indicators. This simple addition will keep all of you
custom indicators grouped together.
