Difference between (a) XT and T group (b) X and B group


PHYSICAL SHARES consultation
P group at BSE ....this is a group where the settlement is in Physical mode /optional demat mode . Right renunciation are listed in this group and Bombay oxygen which has no ISIN trade in this group for around 17500 in Physical mode.Another share is sunil industries ltd which can be traded in physical as well as demat mode.
my broker refuses to deal in this group and may ONLY sell ( not buy )shares if in demat mode as the settlement is optional demat.. which broker deal as there are small trades almost everyday.
