Aspen Graphics receives symbols from its data feeds and in most cases, displays the symbols unedited.
Sometimes, symbols transmitted by the data vendor conflict with a program command or a convention. In these cases, Aspen Graphics must alter the symbol.
This chapter explains the exceptions Aspen Graphics makes for each data vendor.
Aspen Graphics does NOT provide symbol guides for each data vendor. Please call your data vendor to obtain a copy of their specific symbol guide. |
