Methodology

Net carry

The single number that answers “is this position actually making me money?” Fees can look healthy while IL quietly puts you underwater — net carry nets them out. All components are expressed in the position's quote token (token1), so for a stable-quoted pair they read as dollars.

Fees

Uncollected fees are read by simulating a collect() on the position (an eth_call, never a real transaction) from the owner with max amounts. That call pokes the pool to bring fee accounting fully up to date, so the figure is current to the block.

Impermanent loss

IL = the position's value now minus what the deposited tokens would be worth if you'd simply held them (both at the current price). The deposited amounts are reconstructed from the position's IncreaseLiquidity and DecreaseLiquidity events. Fees are excluded from IL — they're counted separately in net carry.

Gas

The real ETH spent across every transaction that changed the position's liquidity (mint, increase, decrease, collect), summed from each receipt's gasUsed × effectiveGasPrice. This is what you actually paid from a third-party wallet — not a subsidized figure. It's valued in USD via an on-chain ETH/USD reference. (Arbitrum Orbit prices the L1 data component into L2 gas, so this closely tracks total ETH paid.)

Range health & market hours

A position is in range when the pool's current tick sits between its bounds. Distances to each bound are percentage moves in price. For pairs with a tokenized real-world asset, LINKEN also flags US-equities market hours (9:30–16:00 ET, Mon–Fri) — the window where the underlying can gap and hit your position while the token keeps trading.
