Providing liquidity
Liquidity is what lets other traders open and close positions at a fair price. On Amoeba’s RAMX and NANDX capped futures markets you can provide it in two ways.
| Earn vault | Your own limit orders | |
|---|---|---|
| Where | Earn → Deposit | The trade ticket, order type Limit |
| What you choose | The amount | The market, long or short, the range, the size and your limit entry |
| Who sets prices | The treasury maker | You |
| How much you can lose | Up to your whole deposit | What your filled positions cost, as for any position |
| What you can make | Your share of the maker’s spread in every market, plus or minus its held pieces at settlement | The difference between your entry and where you exit or the index settles |
| Getting money out | Withdraw at any time, up to what your shares pay now | Cancel unfilled orders; exit positions before settlement; withdraw your balance |
| Fees | None; Amoeba pays the network fee | None; Amoeba pays the network fee |
Deposit into the Earn vault
Section titled “Deposit into the Earn vault”Earn suits liquidity providers who want to back every market without managing orders. One vault holds every depositor’s USDC and funds the treasury maker, which offers to buy and sell every one-point piece of the index range in each market, so any range at any leverage can trade. Your shares are your part of the whole vault. See Earn: deposit into the Earn vault.
Place your own limit orders
Section titled “Place your own limit orders”On a trade page, choose Long or Short, set the range with the leverage and the other end, and select the Limit order type. Enter your Limit entry. If the book does not reach it, the ticket says when it fills, for example “Fills when the price drops to 98.50.”, and your order waits on the book.
- While it waits, the order’s cost is held: a long holds its price, a short the rest of the range’s value. It is not spent until the order fills.
- When it fills, it fills at your limit entry and becomes an ordinary position. Your order can fill against one trader or be combined with several orders and the maker’s pieces, whatever their ranges and leverage.
- Priority. The best total price fills first. At the same price, older orders fill before newer ones, whoever placed them.
Manage it in Account → Ledger:
- Orders lists your waiting orders with Cancel, and the USDC free in each market with Withdraw. Cancelling returns the order’s held cost to that market’s free USDC.
- Portfolio lists your positions with Exit, which sells them at the best price available and pays the proceeds to your wallet.
How the vault is backed
Section titled “How the vault is backed”Every position is fully paid for when it opens. A long pays its price. A short puts in the rest of the range’s value. Together they hold exactly what the range can pay, so every position is backed in full until settlement, whoever is on the other side.
The maker is held to the same rule. Every quote it posts is paid for in full from the vault’s cash in that market at the time, so it can never quote with money it does not have, or with other traders’ money. Losses shrink what it can quote next. When the vault’s cash in a market runs low, traders can still trade with each other there.
Being fully backed is not the same as being profitable. The vault or a limit-order trader can lose what they put in if an index settles against the pieces they hold.
