There's a twist.
Spoiler ahead. If you're sharing your score, do it first, and keep the twist out of the replies.
None of those charts were real. Every one was a random walk, drawn in your browser by a random-number generator. No stock, no coin, no news. Which way price went after your call had nothing to do with anything you could see.
So your score against the monkeys was luck, for you and for every monkey. Tomorrow's charts are a fresh roll. Your archetype is the part that wasn't luck: it's the habit you showed when the outcome was pure chance.
The uncomfortable part: your real trades can feel exactly like this. You see a setup, it works or it doesn't, and after 10 trades you can't tell skill from noise. The only way to find out is to measure your edge over enough trades: win rate, average win, average loss, expectancy.

Why a monkey?
The dartboard monkey is one of finance's oldest jokes: a blindfolded monkey throwing darts at the stock pages could pick a portfolio as well as the experts. Traders have been trying to prove it wrong for 50 years.
This game is a quick way to try. You get 10 charts with the ticker hidden. On each one you go long, go short or sit out. Then 10,000 monkeys trade the very same charts by picking long, short or skip at random, and you see how many of them you beat.
How to play
- Read the chart. You see 60 candles.
- Make the call: Long if you think price goes up, Short if down, Skip if there's no trade.
- The next 20 candles play out. Each trade is $1,000, in at the last close and out at the close 20 candles later.
- After 10 charts you get your monkey score, your trader archetype and a result to share.
The daily game is the same for everyone that day, so you can compare grids with friends. New charts drop every day at 00:00 UTC. Practice rounds give you fresh charts each time and don't count.
Spoilers: how the game works (play first)
The charts are generated, not historical. Each one is a random walk with volatility clustering and the odd jump, so it looks like a real market, with trends, ranges and breakouts. The timeframe label is decoration. The price is a martingale: the expected next price is always the current price, so long and short both average $0. No call made from the visible candles can have an edge.
The monkeys trade the same charts, so the comparison is fair. Your score is luck, and that is the lesson. Ten trades can't tell skill from noise. In your own trading, the way to know whether you have an edge is to log every trade and measure win rate, reward-to-risk and expectancy over a large sample.
The idea comes from Burton Malkiel's A Random Walk Down Wall Street, first published in 1973, which made the dart-throwing monkey famous.
Your archetype comes from your choices: how often you went long, whether you followed or faded the last 20 candles, whether you traded every chart, and whether you sat out after wins but never after losses.
