You're going to let a waitress trade with your demo account. I'm going to let the author of the code run the code, Henderson corrected. He looked at Maya. Ms. Linn, if you can generate a positive alpha in the next 20 minutes using your formula, I will not only believe you, I will hire you on the spot, and I will launch an investigation into the plagiarism claims against you. And if she fails, Julian asked, a cruel smile returning to his face.
If I fail, Maya said, I will sign a non-disclosure agreement stating that I lied, and I will never speak of this again. You can sue me for everything I don't have and I don't have. Deal, Julian said, instantly. He knew the market was volatile today. The Fed had just released interest rate minutes.
No algorithm could survive the choppy waters of the last 30 minutes of trading, unless it was perfect. And he refused to believe she was perfect. Maya walked over to the Swiss investor's laptop. She sat down. The leather chair was soft, a stark contrast to the hard stools in the kitchen.
She cracked her knuckles. She wasn't just fighting for a job. She was fighting for her name. She was fighting for the four years of her life that the Thorn family had stolen. She opened the terminal.
She pulled up the command line. Her fingers flew across the keyboard. She didn't use the mouse. She coded the volatility patch directly into the execution script. Inputting the Heston-Linn parameters, she muttered to herself.
She named the parameters after herself. Julian laughed. How quaint. Watch the screen, Julian, Henderson said. Maya hit enter.
The algorithm went live. On the big screen, a graph appeared. A red line represented the S&P 500, which was currently dipping. A green line represented Maya's portfolio. For the first 10 seconds, nothing happened.
The green line stayed flat. "Dud." Julian said. "It's not executing." "Wait."
Maya said. Suddenly, the green line spiked vertical. "What?" Julian gasped. The algorithm had identified a micro-arbitrage opportunity in the currency futures that the human traders had missed.
It bought and sold within three milliseconds. "Profit." "$14,000." "Luck." Julian spat.
The line spiked again. Then again. It was a staircase to heaven. While the market was crashing, Maya's algorithm was shorting the volatility using the very tail risk Julian had feared as a ladder to climb higher. "Profit."
"$120,000." "Profit." "$340,000." In five minutes, the demo account was up 2.4% in the world of high-frequency trading, that was the equivalent of a miracle. The room was silent except for the hum of the projector fan.
"It's stable." Henderson whispered. "The gamma exposure is neutral. It's perfectly hedged." Maya took her hands off the keyboard.
She turned to Julian. "That." She said, pointing to the profit counter, which was now ticking past half a million dollars, "is what happens when you don't delete the variable for integrity." Julian looked like he was about to vomit. The investors were looking at him with pure disgust.
He knew in that moment that the deal was dead. But he was a Thorn. He didn't lose. Not to the help. He reached into his pocket and pulled out his phone.
He texted his head of security code red in the Onyx Room. "Remove the intruder immediately. Use force if necessary." He looked up at Maya with a shark-like grin. "Well done.
You proved you can code. But you forgot one thing, Maya." "What's that?" She asked. "You're trespassing."
Julian said. "And you just accessed a secured financial terminal without a license. That's a federal crime." The doors to the private suite burst open. Three large security guards in dark suits marched in.
"Get her out." Julian commanded, pointing at Maya, "and confiscate that laptop as evidence." The guards lunged for her. The transition from professional triumph to physical violation was instantaneous. One moment, Maya was the architect of a financial miracle.
The next, heavy hands were clamping onto her biceps, dragging her away from the glow of the laptop screen. "Get your hands off me." Maya cried out, struggling instinctively. The apron she still wore twisted around her waist. "Easy, sweetheart."
The lead guard grunted, his grip tightening to a painful bruise. "Mr. Thorn said remove the intruder. You're trespassing." Henderson stood up, his chair scraping loudly against the marble floor. "Julian, this is unnecessary.
Call them off. We can resolve this like civilized people." Julian stepped between Henderson and the guards, a smug wall of expensive Italian wool. He picked up his wine glass, swirling the dark liquid. "But we aren't dealing with civilized people, Henderson.
We're dealing with a thief, a disgruntled former employee who broke into a private meeting. You heard her admit to accessing the terminal without authorization. That's a felony under the Computer Fraud and Abuse Act." He took a slow sip of wine, his eyes gleaming over the rim of the glass at Maya as she was wrestled toward the exit. "You wanted drama, Henderson.
You got it. But the show's over. The grown-ups have business to conclude." Maya stopped struggling. It was undignified and more importantly, it was useless.
She looked past the beefy shoulders of the security guards, locking eyes with Julian one last time. "You didn't win, Julian." She said, her voice terrifyingly calm amidst the chaos. "You just hit the pause button. The math doesn't lie.
And now they've seen it." "Get her out of my sight." Julian snarled, his composure cracking for just a second. As the doors of the private suite swung shut behind her, cutting off the scent of truffle oil and money, Maya was plunged back into the harsh reality of her existence. She was marched through the main dining room of Le Sommelier.
Diners in pearls and bespoke suits paused, forks hovering halfway to their mouths to gawk at the spectacle. The waitress, the help, being hauled away like common trash. Her manager was waiting by the kitchen doors, his face purple with apoplectic rage. "You're fired, Lynn, obviously. Don't even think about asking for your last check.
It's going to cover the damages to Mr. Thorn's reputation." They didn't take her out the front door. They dragged her through the steaming, chaotic kitchen, past the line cooks who averted their eyes, past the dishwashers spraying scalding water onto plates. They threw her out the back delivery entrance into the grimy alleyway filled with overflowing dumpsters. The cool evening air hit her sweaty face.
The lead guard shoved her forward and she stumbled, skinning the palms of her hands on the rough asphalt. "Stay down and stay gone." the guard spat. "If Mr. Thorn sees your face near this building again, we won't be nice next time." The heavy steel door slammed shut with a sound of finality.
