• First Letter Time - Number of minutes used for the first letter (period) from a Market Profile persective.  This is most commonly 30 minutes, but can be set to 10 minutes for symbols like ZB whose session begins at 8:20am EST.

• Current - Previous - These checkboxes control whether lines will be drawn for the current (developing) and previous day's POC & VAs.

• Color Controls - These color controls allow the user to specify the color and style (solid, dotted, etc) of each of the 4 lines:  Current POC, Current VAs, Previous POCs, Previous VAs.

The RTL token for this indicator is TPO.  When used in the language, in addition to the VA & POCs mentioned above, the TPO indicator provides the user access to IB High and Low, 2x and 3x IB Highs and Lows, TPO counts, TPO counts above and below the POC (both with and without singles).  These are very powerful tools for users interested in backtesting Market Profile related strategies, or charting MP related data on traditional charts.
