Hi,

These particular instruments are a bit unusual in that we create them directly as opposed to them being valid within the Reuters universe. Because both real-time and end-of-day share an instrument list, these instruments were left out of the public list areas.

You can also add these symbols to a custom list, and create some simple online composites using File > New > Composite and add these to a custom list (i.e. NYSE Adv-Dec would be X.NYSE-A subtracted from X.NYSE-D)

There should also be a large list of custom indicators within the Indicator Builder/QuickList that all start with BM NASDAQ or BM NYSE. While these are treated as indicators as opposed to instruments within a chart (using the Security formula function), they might help accomplish what you are looking to do (i.e. BM NASDAQ Arms Index).
