Limits

Accounts on Mirrorlane trade on Plus or Premium, so those are the figures that count. Standard’s are shown where an account still on Standard would meet them.

	Plus	Premium	Standard
Orders and other transactions	4,000 a minute	4,000 a minute, up to 72,000 with LIT staked in Lighter’s app	60 requests a minute, for everything
Reading data	24,000 weighted requests a minute	24,000 weighted requests a minute	Shares the 60

On Plus and Premium, orders and data reads count separately, so reading a lot never holds up an order. Mirrorlane’s own background reads, such as your history and the Markets page, also wait while you trade, so your orders keep the budget.

The exchange also lists a default limit for each kind of transaction, and it isn’t settled whether placing and changing orders fall under it. Until it is, Mirrorlane keeps every kind of transaction under that default, so a burst of many orders in one minute can be held back.

On Plus and Premium, placing orders, changing them and Cancel all also draw on a volume quota. One quota serves every account on your wallet.

Rule	Value
New accounts start with	1,000
You earn	1 more for every $2 you trade
Most it holds	15,000,000, and it never expires
At zero	1 order every 15 seconds
Not counted	Cancelling a single order
Counted once	An order with its TP / SL. A batch counts each order in it.

The Volume quota card in the Account sheet, under Account type, shows what’s left after your last order.

• The exchange refuses the request. A block by its firewall lasts 60 seconds. Reaching the request limit also limits the live connection, and the other way round.
• Mirrorlane slows down first. It counts your requests and holds back before the exchange would refuse. An order that would have to wait more than 3 seconds isn’t queued: the ticket says the request limit is reached and to try again in a few seconds.
• After a refusal, everything pauses. The pause starts at 1 second and doubles while refusals continue, up to 60 seconds.

Open orders rest on the book. Pending orders are accepted but not on the book yet: stops, take profits and TWAP orders. A TWAP counts as one pending order, and its slices don’t count.

	Open, per account	Open, per market	Pending, per account	Pending, per market
Plus	750	250	500	100
Premium	1,500	1,000	1,000	100
Standard	250	30	50	10

At a limit the exchange refuses the new order, and the ticket names the limit you reached. Cancel orders you no longer need to make room.

Each market sets its own steps and minimum. Find them in the Details tab beside the chart (on a phone, the Details tab beside Chart and Book) and in a market’s details on the Markets page.

Limit	What it is
Minimum order	The larger of a minimum size in the asset and a minimum value in USDC. It applies to orders that rest on the book. If a limit order is under it, the ticket tells you the minimum at your price.
Size step	Sizes go in this step.
Price tick	Prices go in this step.
Price band	A sell limit no lower than 95% of the higher of the mark price and the best bid, and a buy limit no higher than 105% of the lower of the mark price and the best ask. Stop and take profit limit orders are measured from their trigger price. The ticket warns before you send an order outside it.
How long orders rest	Limit orders, stops and TP / SL from the ticket expire after 28 days unless they fill, trigger or you cancel them.

Each market has its own maximum leverage: 1 ÷ its initial margin requirement. The Details tab shows it as Max leverage, and the market’s margin and leverage dialog goes from 1× up to it. Some markets take isolated margin only. You can change leverage up to 40 times a minute. See Leverage and margin.

Scale orders, atomic baskets and Close all go to the exchange together, in batches. Mirrorlane sends them 15 orders at a time and splits a larger set into several batches. Every order in a batch counts toward your limits on its own.

Limit	Value
Orders in one scale	Up to 20: the ticket’s Orders button offers 3, 5, 8, 10, 15 or 20
Markets in one atomic basket	Up to 40

In an atomic basket the longs’ and shorts’ percentages add up to 100%, markets you trade in isolated margin can’t join, and a leg under its market’s minimum isn’t placed. Each leg goes as its own order and the ticket shows each leg’s result: it isn’t confirmed that a basket fills all or nothing. See Atomic baskets.

A TWAP runs on the exchange: one slice every 30 seconds, for a running time of at least 5 minutes. It counts as one pending order. See TWAP.

Chase limit, Iceberg and Advanced TWAP run in your browser instead.

Limit	Value
Running at once	10, across Chase limit, Iceberg and Advanced TWAP
Where they run	In your browser, while any Mirrorlane tab is open on the device. Closing the last tab stops them; they pick up again when you come back.
Remember me	Needed. Strategies stay off while Remember me is off.
Their orders	Each order a strategy places expires after 1 hour.
Chase limit	Re-prices every 5 seconds. Chase distance up to 5%. A chunk of 0.01% to 100% of the size, never under the market’s minimum.
Iceberg	A chunk of at most 33.33% of the size. At most 10 orders resting at once.
Advanced TWAP	A running time from 5 minutes, or from 1 minute with Randomize. A slice every 5 to 3,600 seconds.

Deposit from	First deposit	Later deposits
Your wallet on Ethereum, into the exchange’s contract	1 USDC, or about $1 of another asset	1 USDC, or about $1 of another asset
Your wallet, on a network the exchange’s own bridge takes	5 USDC	5 USDC
Ethereum or Tron, by deposit address	$5	$5
Solana or another EVM network, by deposit address or from your wallet	$5	$3
Bitcoin, by deposit address	$10	$10

The deposit screen shows the minimum for the network you pick. Send a little more than it: bridging and swaps can lose some to slippage. See Deposits.

	Secure	Fast
Goes to	Your own wallet on Ethereum	Any address on Arbitrum
Assets	Any	USDC from perps
Minimum	Set for each asset: 1 USDC	4 USDC
How often	Capped by the exchange, counted across every account on your wallet	10 an hour

The Withdraw form shows each asset’s minimum under the amount. Fast also depends on what the Arbitrum pool can pay: the form warns when an amount is more than it, and Fast pauses when the pool can pay nothing. See Withdrawals.

Limit	Value
Minimum	Set for each asset: 1 USDC. The Transfer form shows it under the amount.
How often	Up to 120 transfers a minute
To someone else	Your wallet signs each one

Any fee shows in the form before you send. See Transfers.

Limit	Value
Sub-accounts	16 on Plus, 64 on Premium, 4 on Standard
Creating them	Up to 2 a minute
Deleting them	Not possible
Names	At least 3 letters
Back from Premium to Plus	Not possible once you have more than 16 sub-accounts
Account type	One for your wallet and every account on it
Switching type	Only with no open positions or orders. How often you can switch is set by the exchange.

See Sub-accounts and Account types.

Every account and sub-account has its own key slots, numbered 0 to 254. Lighter’s own apps keep some of the lowest. Mirrorlane gives each of your devices its own key in a free slot, and never replaces a key another app or device uses.

Limit	Value
Keys per device	One for each account you trade from, sub-accounts included. A new key on the same device takes its old slot.
Every slot taken	Revoke an old key in API keys in the Account sheet, then enable trading again.
Standard accounts	A lower cap on keys, which the exchange doesn’t publish
Key changes	Up to 300 a minute
Keys for bots, maker-only keys, read-only tokens	Stay in Lighter’s app

See Your trading key.
