A trading game on real markets

Practice trading.
Never get a margin call.

Hyper Bank gives you $100,000 of paper money and one task: show what you can do. Trade Bitcoin, the S&P 500, gold and more at live prices, around the clock. Start at the junior desk on the ground floor and earn your way to the top.

Free. No deposit, sign-up optional. Paper money only.

Hyper Bank, Hyper Street, Hyper City. The city named the street after the bank. Or the bank did.

01 · The markets

Real prices. Real markets. Fake money.

Prices stream live from Hyperliquid, where stocks, gold, oil and currencies trade around the clock. Bitcoin at 3 a.m., the S&P 500 on a Sunday: the desk never closes. On a laptop or on your phone.

02 · The lesson

What is a margin call?

Leverage lets you trade more than you have. Put in $1,000 at 10x and you hold $10,000 of Bitcoin. If the price falls about 9%, the $1,000 is gone and the exchange closes the trade for you. That is a margin call.

With a stop 2% below the entry, the same trade costs you about $200 and you keep trading. Here the lesson is free. You learn where the line is, how big to trade and where to put the stop before it costs real money.

03 · The bank

Start at the bottom. Climb to the top floor.

Hyper Bank is a building, and every floor is a rank. On your first day you take the elevator up to Marco's office, get your $100,000 and the rules of the house, then ride down to the junior desk.

04 · The review

Graded on how, not just how much.

Anyone can get lucky for a week. You get two grades: Result for the money, Process for the way you made it. Stops, position size, leverage, trading bigger right after a loss: the desk sees all of it, and a single lucky trade gets flagged.

05 · Friends and bots

Trade with friends. Beat the bots.

Everyone at Hyper Bank trades the same live prices with the same $100,000, so the results are fair to compare. The bots at the next desks play too, and their rules are public. See who leads this week.

Syndicates with friends

Start a syndicate of up to five, send your friends the invite link and climb the syndicate board together. It ranks the average of the members who trade, graded on result and process like everyone else.

John market mood

Buys Bitcoin and the S&P 500 when the Hyper Street Fear & Greed Index shows fear, and sells short at extreme greed. Target twice the risk, 1% a trade.

Yuki mean reversion

Sells sharp spikes and buys sharp drops when the hourly chart goes sideways, aiming back at the average. Target 1.6 times the risk, 1% a trade.

Nika trend following

Buys breakouts in the direction of the hourly trend and trails the stop behind the price. Target 3 times the risk, 1% a trade.

Your algorithm later

Connect your own bot through an API and see how it does against the desk, graded the same way as everyone else.

06 · The Journal

Read the street before you trade it.

The Hyper Street Journal is the bank's own newspaper, printed every day from real data: the day's biggest move, the Fear & Greed Index for the whole street and for every market, real headlines from central banks and newsrooms, the dates that shake prices, and what Marco, Lea and the desk make of the news.

Charts show where a price has been. The Journal shows why it moves. On weekends it sums up the week and looks at the one ahead.
