Set up a virtual portfolio with $10,000

By the end of this lesson you can
  • Start the Paper Challenge
  • Understand how the simulator prices trades
  • Write your portfolio rules before trading

How the challenge works

The Paper Challenge gives you $10,000 of simulated cash. You can buy and sell stocks and ETFs in VEXA’s market list at the latest available closing price. Every trade is checked on the server: you cannot spend cash you do not have or sell shares you do not own.

Your result is compared with SPY, an S&P 500 fund, measured from the same start date with the same adjusted prices.

What is realistic and what is not

Prices are real end-of-day closes, not live quotes, and are adjusted for splits and dividends. The game charges no commissions, spreads or taxes, which flatters results compared with real investing. You cannot short, borrow or trade options.

Treat it as practice for decision-making, not as evidence that a strategy works.

Rules first

Before your first trade, write your rules in the journal: maximum size for any one holding, minimum number of holdings, how much (if any) stays in broad index funds, and how often you will review.

Try it in VEXA
Real data, so the numbers will differ from the lesson’s examples.

Key terms

Paper trading
Simulated trading with virtual money to practise without financial risk.
Benchmark
A standard, such as the S&P 500, used to judge performance.
Adjusted price
A historical price corrected for splits and dividends so returns are comparable over time.

Paper Challenge task

Start the $10,000 Paper Challenge and write your portfolio rules as your first journal entry.

Simulated trading with virtual money on real end-of-day prices. Nothing is bought or sold for real, and results in a game do not predict real-world results.
