Open guideFive habits that keep new books alive past the opening hour.
- 1
Learn the ticket before you size up
Open the beginner guide, then the order-types tool. Place tiny limit orders until the tape, spread, and fill quality make sense.
- 2
Respect the margin monitor
Leverage up to 20x works, but the monitor force-liquidates when equity cracks. Use the margin calculator before you press buy.
- 3
Pick a lane: trade, build, or take over
Day-trade the book, run factories through the bill of materials, or climb Observer to Consolidated. Mixing all three on day one is how accounts die.
- 4
Read statements, then size risk
Earnings, DCF, CPI, and rates all feed prices. Scan the strategy tier list, then keep a written thesis with a stop.
- 5
Keep the person alive
Eat, manage stress, and do not skip taxes. A blown body ends a run as surely as a margin call.
Wiki FAQ
Direct answers drawn from the same mechanics this wiki covers in depth.
Is MarginCall a Roblox game?
No. MarginCall is a single-player Windows simulation on Steam from Functionally Human, released 19 August 2026.
Does the market use scripted prices?
No. Prices move only when orders match on a central limit order book. Spreads, slippage, and thinning depth are real.
How do I avoid a margin call?
Cut size, prefer limits, set stops before the monitor does, and keep cash that is not already posted as margin. See the survival guide.
Can I play with friends?
No. The Steam listing is single-player only. You compete against simulated desks, not other humans.
Where are official patch notes?
Steam News for app 4961460. This wiki summarises launch-week patches on the updates hub.
Does MarginCall run on Linux?
Steam lists Windows only. See the system requirements guide. Proton is unofficial.
