Your stake. You start with $3,000 of simulated money (you may choose another amount). There is one bankroll for the whole game.
Shwing's plan. Buy at the next session's opening price. Stop-loss 1 × ATR below the fill, profit target 2 × ATR above it, and sell at the close of session 15 if neither is hit. (ATR is the stock's average daily trading range over 14 sessions.)
Position size. Whole shares only: as many as keep the planned loss within 1% of your current bankroll (about $30 at the start), and never more than you can afford. It is recalculated from your bankroll every edition.
Adjust My Trade. Before deciding you may set the stop (0.25–5 × ATR), the target (0.25–10 × ATR), the shares, and the maximum hold (1–30 sessions). Bigger risks are allowed with a warning; unaffordable or invalid plans are refused.
GO and NO GO. GO adds your plan's simulated net profit or loss to the bankroll. NO GO costs nothing and changes nothing — you still see what would have happened, under both your plan and Shwing's.
How trades are executed. Daily historical prices. If a stock opens beyond your stop, you are filled at that worse opening price — a stop does not guarantee its price. If stop and target fall inside the same day, the stop is assumed to come first. If an opening gap makes your order unaffordable, fewer shares are bought; you never borrow.
Costs. $1.00 commission per side, a 5 basis-point slippage on market fills, the SEC fee (0.00278% of sale proceeds) and the FINRA trading fee ($0.000166 per share sold, at most $8.30).
The record. Every decision is logged — wins, losses and passes, with your plan, Shwing's plan and both outcomes. Download the full record as CSV or JSON at any time.
Game over. The paper folds when your bankroll can no longer fund a single valid position. Reset and try again.
The goal. Grow the bankroll — or at least keep it — and learn which decisions help. Expect to lose more trades than you win: the plan relies on winners being twice the size of losers.
