Margin Call

A trading game on real markets. Start at Hyper Bank with $100,000 of paper money and climb to the top floor. Graded on result and process.

[Margin Call @MarginCallWorld]

On Wednesday Bitcoin settled at 84,455. Tonight it settled at 81,288, down 3.7% in two days.

Our poll leaned yes, 58% of 454 votes. The paper market leaned no, 66%, on just six bets. The market was right this time. One question proves nothing.

Never be too sure. Risk management is for the days you feel certain: 1% at risk, a stop on every trade, discipline.

BLACK THURSDAY, 1929, 97 YEARS ON.
On October 24, 1929 panic selling hit Wall Street: a record 12.9 million shares changed hands, and the bankers who stepped in could only slow it. The crash of 1929 had begun.

THE FOUNDER.
Mr. Hyfeller lived through October 1929 with one rule: never risk what you cannot afford to lose. While the street was wiped out, he kept his capital, and with it he opened Hyper Bank. The rule is still on the wall of every floor: a stop on every trade, one percent at risk, a target worth the risk. Greed is how you get poor.

You set a stop at 1% and lost 2.5%. A stop is not a price: it is an order to sell at the next price available once your level is touched. When the price jumps, there is no one in between. At 1% risk a bad jump costs 2.5%. At 10% it costs 25%. That is why the rule is 1%. Hyper Street Facts, no. 3. Learn it on paper first.

OIL SOARS 3.9% AS GREED RETURNS TO HYPER STREET
Oil rose 3.9% over the last 24 hours to 102.37, the biggest move of the day at the bank.

MOOD: Fear & Greed 61, greed. Crypto (https://t.co/nL3EcXdXLy) 50, neutral.

WE ASKED LEA, RISK MANAGER AT HYPER BANK, about "Renewables Boom Pushes Australia’s Gas Power to Quarter-Century Low":
"Australia's gas power is falling as renewables grow, which hits gas and oil demand over time. Oil is up 2.4% today on $1,000 that is about $24 gained, so the desk keeps stops tight."

@knowRowan Fair question. The line was 41% from five paper bets, now 34% from six, so it is thin: we only just launched. The 360 votes in the poll are the bigger sample (58% yes). The more people bet, the more the number means, so come back and add yours. It settles at 20:00 UTC.

At 10x the price only has to fall 10% before the exchange closes your trade. At 100x, 1%. Bitcoin moves about 2% on a normal day. That is why the rule is 10x at most, and a stop on every trade.

Trading is hard. Ten losses in a row at 1% leave you 90% of your account. At 10% they leave you 35%. That is why the rule is 1% a trade.

@david1989_zhu Good thoughts, and we will take them on board: a cap on open positions and on the total risk across them, so correlated trades cannot quietly become one big one. Thank you for sharing. Responsible trading is the whole idea here, and we mean to push it.
