Not sure how to write a custom PCF, eg- CCI 8 period hourly & DI+ DI- 8 period & TSF 7 Xing a 2 open MA, all hourly, then I want to use these for an Alert triggers.

In general you are better off clicking on an indicator and selecting Create Scan Condition than trying to create a Condition Formula.

Creating Scan and Sort Conditions

An Indicator Formula for an 8-Period CCI could be written as:

(H + L + C - AVGH8 - AVGL8 - AVGC8) * 1600 / 3 / (ABS(H + L + C - AVGH8 - AVGL8 - AVGC8) + ABS(H1 + L1 + C1 - AVGH8 - AVGL8 - AVGC8) + ABS(H2 + L2 + C2 - AVGH8 - AVGL8 - AVGC8) + ABS(H3 + L3 + C3 - AVGH8 - AVGL8 - AVGC8) + ABS(H4 + L4 + C4 - AVGH8 - AVGL8 - AVGC8) + ABS(H5 + L5 + C5 - AVGH8 - AVGL8 - AVGC8) + ABS(H6 + L6 + C6 - AVGH8 - AVGL8 - AVGC8) + ABS(H7 + L7 + C7 - AVGH8 - AVGL8 - AVGC8) + .000001)

Indicator Formulas for +DI and -DI are too long and slow to be practical or for me to post in the forums.

PCF for Wilder's Directional Movement DMI-crossovers
PCF for Wilder's DX, and/or a CI for Wilder's ADX

A Condition Formula for a 7-Period Simple TSV crossing up through its own 2-Period Simple Moving Average could be written as:

TSV7 > AVG(TSV7,2) AND TSV7.1 <= AVG(TSV7.1,2)

Any changes to these settings would require adjusting the formula.

There is a Time Frame drop-down menu available when creating or editing a Condition Formula which will allow you to adjust its settings.

Personal Criteria Formula Conditions

In either case, you will probably want to use the Conditions as EasyScan Conditions.

Thanks, that was a TSF (time series forecast) not TSV, would I just change the TSV to TSF?

A Condition Formula for a 7-Period Time Series Forecast with Forecast Bars set to 1 crossing up through a 2-Period Simple Moving Average of the Open could be written as:

AVGC7 + 4 * (3 * C + 2 * C1 + C2 - C4 - 2 * C5 - 3 * C6) / 28 > AVGO2 AND AVGC7.1 + 4 * (3 * C1 + 2 * C2 + C3 - C5 - 2 * C6 - 3 * C7) / 28 <= AVGO2.1
