Gap Adjusted Moving Average Chart - This chart plots a gap-adjusted moving average in pink.  This moving average is implemented with a custom indicator and therefore requires the pro version of Investor/RT.  This is a 20 period simple average.  Notice the red line meets up with the standard 20 period simple MA on the 20th bar of the session.

The syntax of the custom indicator follows:

((POS >= 20) * MA) + ((POS < 20) * (MA + SESST_CH * ((20 - POS)/20)))

This custom indicator is setup for a 20 period average.  To adjust this periods, simply change the four 20s seen in the syntax to the period desired, and change the period with the MA token to that same peroid.
