Prop Trading CEO: Risk Management Is the Real Product

That distinction changes the technology roadmap. Evaluation parameters stop being a sales lever. A high pass rate becomes a potential warning sign, because it can signal that a firm is expanding funded exposure faster than its risk framework can support, Hertzberg wrote.

Hertzberg wrote that firms need real-time visibility into aggregate positioning and product concentration on the funded side. Individual account performance is not enough. With that visibility, a firm can act before exposure becomes a problem, he said. It can tighten position limits and adjust parameters on specific instruments. It can also slow funded account activation during periods of elevated market risk. Without it, none of those moves are possible.

Risk management is not a system, Hertzberg wrote. It is a reaction. Most firms built their platforms to solve the immediate problems in front of them: onboarding traders and processing payouts. Those are operating mechanics, not processes that ensure profitability.

"If you lose a dollar for every widget you produce, you won't make it up in volume," he wrote.

Building risk management in after the fact costs more and often comes too late when market conditions shift, Hertzberg added. The funded base does not forgive gaps in visibility. It makes them more expensive over time.

Firms that built risk management into the platform from day one can enter volatile periods with systems designed for that moment, he wrote. Their understanding of funded-side exposure sharpens with data.

Firms that keep treating the challenge as the product are focused on the wrong thing. "The funnel is not the business. The funded base is," Hertzberg wrote.
