Make a real quant decision: evaluate a trading strategy using expected value, break-even analysis, Monte Carlo simulation, and stress testing. Determine whether to trade or not trade—and justify your verdict.

A statistical testing framework for strategies, built section by section - hands-on, but never alone. Theory first, then you implement it, and checkpoints confirm each section clicked before the next one opens.
Never stuck
Reveal a hint when you want a nudge - or the full worked solution when you want the answer. Every exercise ships one.
Theory before code
Each formula is explained step by step before you implement it. Nothing is assumed mid-build.
Yours to keep
Finish with the complete research notebook - keep extending it with your own data.
Real code from inside the project. Press Run to t-test a strategy that genuinely has an edge - and watch one year of data fail to prove it. Open this page on desktop to run it live in your browser.
import numpy as np
rng = np.random.default_rng(11)
# A strategy with a real but small edge: 3 bps a day under 1% daily noise.
daily = rng.normal(0.0003, 0.01, 252)
mean, std = daily.mean(), daily.std(ddof=1)
sharpe = mean / std * np.sqrt(252)
t_stat = mean / (std / np.sqrt(len(daily)))
print(f"annualised Sharpe : {sharpe:.2f}")
print(f"t-statistic : {t_stat:.2f} (need about 2 to call it real)")
print(f"verdict : {'edge is real' if t_stat > 2 else 'could still be pure luck'}")The full build covers Sharpe inference, sample size, and the traps that fake an edge.

Interview ammo
“Explain why win rate alone is insufficient to determine strategy profitability—need payoff sizes and costs”
You answer this with a system you built, not a definition you memorized.
