MarginCall Trader Desk Tier List

Hundreds of participants price the book with their own cash, skill, and bias. The store page names the archetypes; the simulation lets them blow up. This list is about reading the opposite side, not about unlocking skins. Use it with Strategy Tiers when you decide whether to fade a chase or sell into a market-maker.

S — Market-makers

They quote two-sided liquidity until they cannot. After float-cornering patches, a per-company maker cannot invent infinite offers or short what it cannot borrow. When Avail is healthy, makers are your friend: tighter spreads, cleaner limits. When Avail is dying, they vanish like everyone else. Trade with them, do not worship them.

A — Value desks

They buy cheap and short absurd. If you are running a value loop, they are competitors and confirmation. If you are running a story stock, they are the offer you eventually meet. Their information is imperfect on purpose, which is why cheap can stay cheap. Read statements anyway; see Controls for Financials and Analysis.

B — Momentum funds

They chase. Useful when you want a tailwind. Lethal when you are the exit liquidity. A B rank means they move prices for real, not that you should copy their last print. Hedge funds in this family can overreach and die. The store copy says you can buy them out. Treat that as a distressed-control opportunity, then use How to Take Over Companies so you do not inherit a bomb.

C — Bubble-chasers

They will pay 200x earnings for a narrative. Excellent if you are distributing. Catastrophic if you joined them at 199x. Ranked C because they create the mispricings the rest of the ecology lives on, not because they are wise.

D — You, on 20x, with no stop

The worst desk in the sim is an unsupervised human. The monitor is the risk manager you did not hire. Read How to Survive Margin Calls before you compete with people who at least have a mandate.

How to use the ecology

Watch who is on the bid when a name rips. If makers pulled and chasers remain, you are in a crowd. If value is still offering stock, you might be early and wrong. Thesis notes exist so you can record which desk you think you are fading.

Buying out a wrecked fund is not the same as understanding its book. Look at remaining shorts, options, and any nested holdings. Sound Money made money conservation stricter; you should too.

When you know the desks, pick an asset class they cannot all stand in at once. Crowds thin some books and light other ones on fire.

Reading the opposite side in practice

Before you fade a rip, ask three questions. Who pulled the bid. Who is still chasing. Who is quietly offering stock. Makers going quiet plus chasers lifting is a crowd. Value still offering into a melt-up is either a gift or a trap; your thesis card should say which you believe and where you are wrong. Buying a wrecked fund because the store page said you could is not a desk read, it is a liquidation sale. Open the remaining book, look for shorts and options, then size the bid like a trader, not like a collector. Pair this page with Strategy Tiers so you do not copy a C-tier personality on an S-tier plan.
