A game market, not a stock exchange
Streaks and the Market in the daily investing game
On erstwhile.io, a streak is how a player-made ticker is born. Three days claims the name. Five days starts it at $10. Ten days puts it on the public Erstwhile Market. This is a game board. It is not a brokerage.
| Field | Reading | Status |
|---|---|---|
| 3 days | Claim a ticker of 2–4 letters. Not trading yet. | Official · 1 source |
| 5 days | Starts at $10.00. Price moves with your days versus the S&P. | Official · 1 source |
| 10 days | Joins the public ranking. Columns: rank, ticker, price, today, market cap. | Official · 1 source |
| Miss a day | The streak resets. Supporters get one streak save a week. | Official · 1 source |
| Snapshot | On 11 November 2026 the board listed 3 tickers and called itself new. | Official · 1 source |
| Penalties | A warning, a 3-day trading halt, or delisting. A person reviews the case. | Official · 1 source |
What moves the price
The how-to-play page and the FAQ agree on direction: the ticker goes up on days you beat the S&P 500 fund and down on days you do not. They do not publish the size of the move. I am not going to estimate a formula. After each day’s puzzle, the public table refreshes price, today’s change, and market cap.
The board I saw on 11 November 2026 said the Market was new and to expect changes. Three listed names is a snapshot of that morning, not a capacity. I will not treat it as a population.
Fair play
The terms page describes checks for play that looks like someone learned the years from another window. The listed outcomes are a warning, a three-day halt on the ticker, or removal from the board. Daily results can still count unless they are removed. A person reviews the case. I do not have the internal checklist, so I stop at the outcomes the terms actually name.
Questions
Is this a real stock?
No. The ticker is a game object tied to your streak. It is not a listing on a public exchange.
Where is the leaderboard?
The Market table is the public ranking, and only after a 10-day streak. The daily rank on a certificate is a different list.
