I put the following question in the 'Trading Software' forum last night, but didn't get an answer. Does somebody here know? In IB's workstation under the 'Top % Loser's' of the day, there are a number of underlyings I can't find. Does anyone know the stock names for the following symbols? C PRE, C PRF, C PRI, C PRM, C PRO, C PRP, C PRQ, C PRR, C PRS, C PRU, C PRW ?
