The Inbox: Listener questions and comments

• Comment from Aman117 - Ever thought about hosting a cyber security roundtable on the show with exchange, broker and trading firm CTOs? Talk about who is hacking them and what they’re doing to stop it? Could be interesting.
• Question from Amanda F - Looks like budgets for #tradingtech are dwindling with much of that money going toward comp and reg. Any bright spots on the horizon that the tech spend may be increasing or is regulation going to continue to rule the day.
• Question from JVZ16 - What do you think it will take to get stock and options exchanges to adopt the speed bump that you advocated on the last episode? A catastrophic error or failure of an HFT firm that causes massive losses and negative publicity?
• Question from Big Rig - Love the program. You and henry breaking stuff down every month makes my long hauls a little shorter. So thanks for that. I have heard you guys discuss the problem of the lack of new market makers in the biz. Can technology not replace some of that? We have already got robo-advisors. Do you foresee the day of the robo-market makers anytime soon?
• Question from Cookie -What is the best online platform for stock options and futures options?
