Need Formula for NYSE Cumulative Tick Indicator

[Timber]

I need help in creating an indicator based on the NYSE Tick indicator. Specifically, I need a running 13-period total of half-hourly NYSE TICK readings placed on a price study chart.

thanks,
timber

Hello Timber,

Set your chart interval to 30 minutes and apply the attached formula. This formula will plot the 13-bar cumulative $TICK as a histogram and may be used in conjunction with any symbol in your advanced chart. The period length is also adjustable through the "Edit Studies" option.
