From Bloomberg terminals to Zoom, traders at Wall Street's biggest firms are building massive work-from-home setups to get an edge. We spoke to dozens of insiders about how they're handling unprecedented market chaos.

• Much of Wall Street's trading force is now working from home. But trading remotely comes with disadvantages.
• "Trading from home has never been done," a trading at exec at one of the biggest banks told Business Insider, referring to the company's business continuity plans. "It was not part of our playbook."
• Many large banks have replicated a trader's office setup in their living room, including computers, monitors, Bloomberg terminal access, phones, and direct access to the bank's systems.
• Trading turrets - control centers that allow rapid-fire voice connection to colleagues, brokers, and clients - are a key part of how trading floors normally function. One hang-up of moving remote was the lack of turrets, a senior trader said.
• We spoke with more than a dozen insiders to understand the massive undertaking to enable remote trading, and which qualities of a trading floor are hardest to replicate from home.

That's because trading remotely comes with disadvantages and headaches. Some are tangible, while others are harder to grasp for the uninitiated. We spoke with more than a dozen insiders to learn exactly how banks are tackling the massive undertaking, and which qualities of a trading floor are hardest to replicate from home.

Citi's North American markets division started to test-drive WFH capabilities for traders the first week of March, sources familiar with the preparations told Business Insider.

And Goldman Sachs is trying to approximate being in the same room with colleagues by exploring special videoconferencing setups, according to Atte Lahtiranta, the firm's chief technology officer.
