I have constructed a PCF in the Custom Indicator Settings window for the DJ-30 as follows(C-C10)*SQR(V). When I test the formula the answer is -465577.02. Charting this PCF in the middle window and not using either the Center Zero Line or the Plot using price scale, the scale for this PCF ranges from a high of 2,051,341 to a low of -2,919,445. My question: is this charted line a cumulative? How is the answer -465577.02 for 5/27/08 used when the last point for the chart line is above 808,645 on the chart scale? How does it fit in relation to the scale? Thank you for any assistance you can provide in answering this puzzle. David Salke 158044

When you click the test formula button, can you type in everything here that comes up?

QUOTE (Dwzrd) My question: is this charted line a cumulative?
No. You will need to use a Custom Cumulative Indicator instead of a Custom Indicator if you want a Cumulative result (set the Up Condition to something that is always True like C > C - 1 and the Down Condition to something that is always False like C < C - 1). It should be noted that the actual value is meaningless when this is done.

The value for 5/27/08 matches my result, but I'm definitely not showing the charted line above 808645 on the chart scale for the most recent value. Is your Chart using a Daily Time Frame?

Since you have Center Zero Line checked, the Scale will run from largest visible absolute Value of your formula on the visible portion of the chart to the negative of this value. You may wish to review the following:

C10 in the Test shows 12876 and change, when in reality C10 (from yesterdays' close) is closer to 12302. Forwarded to QA for testing. The indicator on the chart appears correct, but not the numbers being returned by the Test.

What I'm trying to figure out is how the daily answer to the PCF calculation is posted to the scale. On a daily chart is each daily answer posted as it is calculated or is it added to the last calculation.

Dwzrd,
It is posted as calculated. It is not cumulative in any way unless you are using a Custom Cumulative Indicator.
