A $1,000 course will explain the market to you. Here you trade the real one, live, and every mistake is free.

Three steps, start to finish

A trade takes about ten seconds to open and you can close it the moment you change your mind. The ticket on this page is the real one: try it.

  1. 1

    Pick a coin

    Hundreds of them: every coin traded on both Binance and Coinbase. The Markets page ranks them by how much each has been swinging lately, most volatile first, so you can go where the action is.

  2. 2

    Go Up or Down

    Up means you think the price will rise; Down means you think it will fall. Choose how many Sim Dollars to put in and a multiplier, anything from 1x to 1000x. Stop loss and take profit are there if you want them.

  3. 3

    Close whenever you like

    One trade at a time: while it's open the ticket becomes a card showing what it's making, with one button to close it. Closing locks in the profit or loss, and every closed trade is kept, with how it closed and what it made, so you can look back at your calls.

What you get

A real market to learn on, and the tools to learn it properly.

Most people learn to trade by losing real money. Here you learn on the same live market, with tools that show you what you're doing and why it worked or didn't. The mistakes still teach you; they just don't cost you.

5 sec1 min5 minBollinger Bands: price is pressing the top of its band, which often means it's stretched.

Learn to read the chart

Indicators that explain themselves

Trend signal, Volume, Bollinger Bands and RSI, each with a line of plain words saying what it sees. Watch them react to real prices, down to five-second candles, until you can read the chart without the words.

Manage the risk

See the danger before you trade

Stop loss, take profit and the exact price that wipes out a leveraged trade, drawn on the chart. Find out what 50x really means without paying for the lesson.

Learn from hindsight

What if you'd gone in then?

The what-if card shows what a trade opened earlier would be worth now, Up and Down. Check a hunch against what actually happened before you put anything on it.

Review your calls

Every trade, kept

Each closed trade is saved with how it closed and what it made, so you can spot what's working and the habits that keep costing you. Free keeps your last 300; Pro keeps them all.

Know where you stand

A score you can't buy

Your result is measured against everything you've put in, so buying Sim Dollars never moves it. Only your trades do. When it climbs, that's your trading getting better.

// two moving averages; the cross is the signal
const quick = sma(closes(), 10);
const slow  = sma(closes(), 30);
plot('Quick 10', quick, { color: '#2bff5e' });
const up = quick.at(-1) > slow.at(-1);
say(up ? 'leaning up' : 'leaning down');

Want more Sim Dollars?

Every account starts with $1,000. If you want to trade bigger right now, buy a pack from inside the app, on either plan. The bigger the pack, the less each thousand costs: from 80¢ down to 33¢.

    Sim Dollars from a pack can't be withdrawn or exchanged, and buying them never counts toward your result or your place on the leaderboard. Buying packs often? Pro tops you back up to $10,000 every 8 hours, for $20 a month.

    Questions people ask

    Are Sim Dollars real money?

    No. Every account starts with $1,000 of play money. You can buy more if you run out, but you can't withdraw them or exchange them for anything, and nothing here pays out. Your result is a score, not a balance.

    If I buy Sim Dollars, does that count as profit?

    No. Your overall result is measured against everything you've put in: the starting $1,000, anything you've bought, and every Pro top-up. So topping up never moves your result or your place on the leaderboard. Only trades do.

    Where do the prices come from?

    Live from real crypto exchanges, over a direct connection from your browser, and they update every second. Your trades are recorded in your Sim Street account only; they never reach the exchanges.

    Why does the leverage go up to 1000x?

    Because without leverage a five-minute trade barely moves, and the point is to feel how it works. With 50x, a 2% move against you wipes out the trade; with 1000x, 0.1% does. Seeing that happen with play money is the lesson.

    Do I need an account?

    No. You can start trading straight away and your account is saved in your browser. Sign in when you want it on every device, or to go Pro.

    Is this financial advice?

    No. The Buy and Sell arrows, the indicators and everything else on the chart summarise what the price has already done. None of it predicts anything, and nothing here is a recommendation to trade real money anywhere.

    What happens if I cancel Pro?

    You go back to the free plan. Your account and your trades stay, including whatever Sim Dollars you have; the 8-hour top-ups and the Pro tools switch off, and closed trades beyond the most recent 300 stop being kept.
