Catracho,
This is not covered in "SFA" exams, in this instance the Registered Rep's exam (unless it's changed - long time ago).
What do I remember of this "professional" exam? "Which countries have (had) five day settlement?" Answer: Netherlands, USA, Australia, ie the three "A's" (Amsterdam, America, Australia). Teaches everything you don't need, nothing you do need. What a crock.
Correspondingly, market-makers have also changed. To a man, they're all from Essex but "connected" to the East End. Therefore, address them accordingly, eg "'ere, gor blimey, guvnor.. naaa, whaat? naaa, wot? fack orf.. leave it out... wot? would you adam an' eve it, boll-ucks, fack orf... you wot.. . you gotta be fackin' kiddin' me.. woot? naaa, fack orf, leave it out, Go' bless 'er, you wot, naaaa, Barbara Windsor... 'ere, wot?, you gotta be fackin' kiddin' me, naa, knock it on the 'ead.. naaa...you wot? boll-ucks, naaa, fack orf. That's fine, thank you, 100 at 125. We're BZW, 1438. Thank you, Sir. No, thank you, Sir. Thank you. Thank you. 'Bye, 'bye. Cockney fcuk."
