Whenever possible, ddfplus will retain the exchange symbol for a given security. However, there are circumstances, detailed below, where ddfplus has to convert the incoming exchange symbol to conform to our standards.
Preferred stocks are notated on the ddfplus feed with a "-" within the symbol. The exchange will pass down a lower case "p" which ddfplus will convert to a "-".
Example: Ford Motor Corp Preferred "FpS" can be viewed as "F-S"
Warrant stocks are notated with a ".W" at the end of the symbol. The exchange will pass down "/WS" which ddfplus will convert to ".W".
Example: Conseco Warrant "CNO/WS" can be viewed as "CNO.W"
Class A and Class B shares are noted with a ".A" or ".B" at the end of the symbol. The exchange will send down "/A" or "/B" which ddfplus will convert to a period and then a letter following the ticker symbol.
Example: Berkshire Hathaway Class A "BRK/A" can be viewed as "BRK.A"
Example: Viacom Class B "VIA/B" can be viewed as "VIA.B"
