What happens to your execution when the market breaks? A brand-new opening format for 2027: three plausible-but-uncomfortable shock scenarios — a Fed policy surprise, a tariff escalation spiral, a crypto-equities contagion event — put to a panel of senior trading heads live on stage. But this isn't a macro forecast. It's a stress test of the desk itself: spreads gap out, depth evaporates, dark pools go quiet, and algos calibrated on calm markets start chasing liquidity that isn't there. For each scenario, the panel discusses the problem in real time — which orders do you pull, when do you override the wheel, what do your pre-trade analytics flag before the tape confirms it, and how do you even measure execution quality when every benchmark assumes a market that no longer exists?
