My response may not be on the mark for you since you were brief in stating any needs.
Those you listed are selling things. One example: Oliver harps on how to trade a 20 and 40 ma tracking in parallel. But he never gives one peep on how to find such situations as they develop. Lots of hype all the time as well.
Ruggerio and Persons can't help you with systems. not modelling, not development not debugging nor operating.
BUT if you want to code tons of stuff you can get up to spped very rapidly using some stuff that will be presented in a series of sessions each building upon the other. Go see Chris at Worden Bros and in particular their analytical support software.
Secondly wealthlab sessions are conducted by several fidelity people. try to Skip the quant stuff simply because none of the stuff ever happens during the year. The advanced session will draw some talent from the audience. There are a lot of super traders and programmers floating around.
The best ones are support people for guys you have never heard of. They will be on the stage last (as usual) but some of them are there for other reasons. All are accessable if you know who they are.
I could go on with this but it may be a waste of time.
trading live in vegas is a misnomer. See dates of conference.
The hottest trader will be on during the lunch trading period. he was pissed in San diego but I see they screwed him yet once again. John Netto is on Friday am Vegas time which is lunch time in east and Chicago.
Before this session there is a 6:00 am start for live trading with CME types. These guys are sleepy heads BUT the audience has some hotshots.
So go to 6:00am and then swing over to NETTO and then return to CME for debriefing.
The debriefing is where you FIND traders not on the stage. Listen to Q's. And catch up with some of these guys later.
The the three annual TE's, Vegas is tops San Diego the poorest and New york is cold and a lot of people talk fast there.
Vegas is relatively cheap.
