Ray tutorial is an Educational Resource for CLMM Price-Range Management

How wide should a Raydium CLMM range be?

A Raydium CLMM price range is the active interval, and its width should reflect expected movement plus the cadence at which you will review it.

Begin with the pair, not an arbitrary percentage. USDC/USDT trades around a tighter relationship than SOL/USDC, so the same band width creates very different monitoring demands. Raydium places boundaries on discrete ticks rather than any decimal price you type. One tick changes the protocol price by a factor of 1.0001, equivalent to about 0.01% or 1 basis point. The pool fee configuration then limits usable boundaries through tick spacing. Published Raydium CLMM configurations pair 0.01%, 0.05%, 0.25% and 1% fee tiers with spacings of 1, 10, 60 and 120 ticks.

Center the band around a defensible price

Price centering determines which boundary the market reaches first. Use the prevailing pool quote as the reference, then confirm the displayed direction before setting limits. A quote shown as USDC per SOL reverses when viewed as SOL per USDC. For a log-symmetric band, the reference price equals the geometric mean of the lower and upper limits. That relationship places equal multiplicative distance on both sides, matching the exponential tick grid.

Match width to the pair’s movement

Correlated assets such as USDC/USDT and mSOL/SOL support tighter bands because their relative prices move within a narrower economic relationship. SOL/USDC needs more room because SOL itself carries the directional move. A tight range supplies greater liquidity per unit of capital near spot, yet it reaches a boundary sooner. A broad range spreads the same capital over more ticks, reducing fee density while extending active coverage.

Choose a band your review schedule can support. An interval demanding hourly attention conflicts with a weekly routine, even when its projected fee rate looks attractive. Range width becomes an operating commitment as soon as the position opens.

When does CPMM beat a concentrated range?

Raydium CPMM is a full-curve liquidity model, and it fits capital meant to remain active without price-band management. Raydium CLMM, Uniswap v3 and Orca Whirlpools concentrate liquidity between boundaries, while Meteora DLMM groups it in discrete bins. Those systems demand range or bin decisions. Raydium CPMM spreads liquidity from prices approaching 0 toward unbounded high prices and issues fungible LP tokens; a CLMM position uses an NFT with supply 1. Choose CPMM when persistent two-sided activity matters more than fee density near spot.

In-range and out-of-range position states

A Raydium CLMM position state is a tick comparison determining whether its liquidity joins swaps, accrues new fees and changes token composition.

A position is active when tick_lower <= tick_current < tick_upper, making the lower boundary inclusive and the upper boundary exclusive. Active liquidity contributes to PoolState.liquidity, so the position receives its proportional share of LP fee growth during swaps. Outside the interval, its active-liquidity share is 0% and new fee allocation stops. Previously accrued fees remain attached to the position. If the current tick later re-enters the interval, participation resumes automatically from that point.

Above the upper boundary

An upper-bound exit converts the position fully into the quote side under the protocol’s standard token orientation. When price means token1 per token0, a price at or above the upper limit leaves 0 token0 and only token1. For a SOL/USDC position represented with SOL as token0, the balance is therefore USDC. The upper tick itself sits outside the active condition, so fee growth has already stopped there. For a worked version, see Ray in practice.

Below the lower boundary

A lower-bound exit produces the opposite composition. Once tick_current falls below tick_lower, the position holds token0 and 0 token1 under the same orientation. The exact names shown by Raydium follow the pool’s mint ordering, which might differ from the visual base-and-quote order. Read the displayed token balances together with the price direction before interpreting exposure.

Out-of-range status preserves the position NFT and its accrued balances in PersonalPositionState. A later re-entry activates the same two boundaries, giving the owner a clear choice between waiting and redeploying capital.

What should you do when the position leaves its range?

An out-of-range Raydium CLMM position is inactive liquidity, and the right response follows from your desired asset exposure and return threshold.

Waiting keeps the original boundaries and single-asset balance ready for a market return. Recentering withdraws liquidity and opens another position around the new price. A layered approach leaves the old position intact while placing part of the capital in a second range. That second range receives its own NFT with supply 1, allowing separate boundaries and accounting.

Recentering changes economic exposure immediately. Closing an upper-range SOL/USDC position realizes its USDC-heavy composition, while a newly centered position needs both assets at the ratio its new boundaries require. The conversion and redeployment create trading costs, price impact and fresh Solana account costs. SOL pays the network’s 5,000-lamport base fee per signature plus any priority fee and rent for new accounts. Raydium pools also support up to 3 reward slots, yet reward growth follows active liquidity just as swap-fee growth does. A projected reward stream therefore does not compensate an inactive range until price returns or capital moves.

The decision rule in this Ray tutorial is to compare expected incremental fees with the cost and exposure change of redeployment. Capital should move only when the new band serves a defined price thesis and monitoring cadence, because repeated recentering turns temporary divergence into settled portfolio changes.

A worked SOL/USDC range calculation

A worked SOL/USDC range calculation is a boundary test showing how a balanced-looking band becomes a fee-inactive, single-asset position.

Set the inputs

All changing inputs in this hypothetical are defined here: the displayed quote is USDC per SOL, entry is 150, the lower boundary is 120, the upper boundary is 180, the later price is 190 and the selected pool tier is 0.25% with tick spacing 60. Raydium maps entered prices to valid ticks, so the limits displayed after rounding are the operative boundaries.

Reach the position result

The lower limit sits 20% below entry: (150 - 120) / 150 = 0.20. The upper limit sits 20% above entry: (180 - 150) / 150 = 0.20. Later, SOL rises 26.67% from entry because (190 - 150) / 150 = 0.2667. It also stands 5.56% above the upper boundary because (190 - 180) / 180 = 0.0556. Since 190 exceeds 180, the position is out of range.

The concrete outcome is a 0% active-liquidity share for this position, 0 SOL remaining under the stated price orientation and a USDC-only balance. The 0.25% pool tier still applies to eligible swaps, but this position receives none of that new fee growth while price stays above 180. A return below the valid upper tick restores activity; recentering instead establishes a new pair of boundaries.

Ticks, accounts and fee growth under the hood

On the cost side, Raydium CLMM range mechanics are stored in Solana accounts, with each position linking 2 ticks to a specific pool and owner NFT. The Raydium CLMM grid runs from tick -443636 to 443636, and each tick multiplies protocol price by 1.0001. PoolState stores a Q64.64 square-root price scaled by 2^64, AmmConfig sets spacing and TickArrayState packs 60 entries. At spacing 60, one array spans 3,600 integer ticks. Two token vaults hold the pair assets, linking every range decision to on-chain state.
