At StockDynasty you found your own corporation and trade shares of other players.

I personally stepped onto the virtual trading floor on 04/04/2026 and have been active there daily with my corporation "Hirgorath Investment." As part of the "Pirates of the 7 Stock Seas" I belong to one of the strongest alliances there.

• Fix: New chat messages on the dashboard did not appear live for players without an alliance (only visible after reloading the page)

• Fix: Notifications for trade executions, dividends and maturing bonds incorrectly always showed the AG symbol instead of correctly distinguishing between private and company [Suggestion #173 by Wirklicht]

What a chunk of an update... it's really fun to be part of the development. Discovering every little new thing.

Game-wise I was lucky too - I did a capital increase last weekend and this time it was larger than the previous ones. It was a good decision - I can't do another one until the end of January. Lucky me.

The best part of the update for me is the new design - my eyes thank you ;)

Prices are formed by player orders. The central bank and some system bots still move between the ask and bid price if things get too quiet. They are, so to speak, the market makers.

I structured my capital increases so they barely diluted the shares. There wasn’t a price crash — on the contrary — it rose surprisingly and is currently well above book value.

The cooldown on capital increases is a bit annoying. To avoid dilution I have always issued only a few new shares. Because of the cooldown I can no longer do that and have to go all-in — which brings the risk of dilution. However, I’ll use the time until January for share buybacks (capital reduction) — I don’t think I’ll do any more increases because of the cooldown. For now I have enough capital anyway.

For the central bank, it is fairly clearly documented:

Quote

The central bank (CB) acts as an automated market maker. It provides liquidity by buying and selling stocks and options. All parameters can be configured by the admin.

Stock Sales by the CB

The CB sells remaining IPO shares. The initial price is calculated as book value × markup (110.0%) × random factor (0.95–1.05). For subsequent sales, the last trading price × (1 + price increment (10.0%) × random factor (0.8–1.2)) is used. The sales quantity is total shares × share (7.0%) × random factor (0.5–1.5). The cooldown between sell orders per company is 30.0 seconds.

Stock Purchases by the CB

If there is no buy order in the order book, the CB places a bid at book value × factor (95.0%) × random factor (0.95–1.05). The budget is €50,010.

Price Depreciation

Unsold CB orders regularly lose value: -2.0% every 20.0 minutes.

At random, the CB skips individual companies (default: 15% probability) or cancels existing orders (default: 5%).

The sys-bots are a bit more guarded about it. Each one does things a little differently. Some make a profit, some remain stagnant, and some incur losses.

The game provides an API that could surely be used to build something.
