MasterDATA's Composite Plug-in for
MetaStock
and historical composite breadth datafiles on 31
major stock indexes and the 111 highest trade volume
ETFs.
The following
two formulas allow MetaStock to access any statistic in your downloaded
historical composite breadth datafiles to address a wide variety
of situations from very simple to very complex:
ExtFml(
"MD.BySym", YourValue) - 1 parameter This formula will appear to act much like
a "normal" MetaStock function. The plug-in determines
the MetaStock base * symbol,
and returns a value based upon that symbol, the statistic
and the base symbol's data period. But, instead of
calculating the statistic within MetaStock itself, the above
formula calls the plug-in. The plug-in looks for a
datafile corresponding to the base symbol (plus the configured
file extension) and retrieves the appropriate value from
that datafile. In other words, if you have an Intel
(symbol: INTC) chart open and apply a custom indicator containing
the above formula, the plug-in will look for a datafile
named INTC.csv (or your configured file extension) in the
directory you specified in setup. Once the plug-in
finds your datafile, the column containing the statistic
name ("YourValue" in the above example) is determined and
the column's values and dates are synchronized with MetaStock's
price data for INTC. Then the values are returned
to MetaStock. MetaStock then uses these retrieved
values to calculate your custom indicator.
*
The "base" symbol is the symbol currently being used by
your MetaStock function. If you are looking at a chart
of the PowerShares QQQ ETF, the "base" symbol is the symbol
for the PowerShares QQQ ETF, QQQQ.
ExtFml(
"MD.ByFile",CompositeSymbol, YourValue, DataPeriod)
- 3 parameters This formula provides much greater control over
the data retrieved by your MetaStock function. Three
parameters are entered as follows:
Composite Symbol To use statistics from a specific datafile, enter
that file's symbol. To use the base symbol currently
used by the active MetaStock function, enter "BASE".
Statistic Value As in the previous plug-in formula above, the
plug-in finds your datafile as specified in the first
parameter, then finds the column containing the statistic
name ("YourValue" in the above example) and then reads
the column's values.
Data Period To use statistics from a specific data period,
enter the desired data period (d or daily, w or weekly,
m or monthly or q or quarterly) as the third parameter.
To use the data period of the current base symbol,
enter "BASE".
The use of this plug-in formula allows
charts and indicators never before possible in MetaStock
such as multiple data periods in the same chart, constructing
an indicator for one static issue that uses the base data
period of the current MetaStock function and much more.
