Charting a Formula

Any formula or function you have defined may be charted.

To chart a formula that contains instrument symbols (i.e., MY_FORMULA=IBM-MSFT), display a chart window and type the name of your formula, i.e.,

MY_FORMULA

Then press b. The formula is graphed in the chart window.

If the formula requires you to supply instruments (i.e., MY_OTHER_FORMULA=$1-$2), you must append a parenthetical statement containing the instruments to the end of the formula, i.e.,

MY_OTHER_FORMULA(IBM,MSFT)

The number of instrument symbols you must supply corresponds exactly to the number of variables in your formula, and all instruments you supply must be separated by a comma (,).
