Liquidity Analysis

Liquidity Analysis — DEX Depth Assessment for Solana Tokens

Liquidity analysis answers three critical questions before every trade: Can I get in at a reasonable price? Can I get out when I need to? and Is this pool safe? Without it, you risk excessive slippage, failed exits, and rug pulls.

Why Liquidity Analysis Matters

Position sizing: Maximum position size is bounded by available liquidity. A $10K position in a pool with $20K TVL will move the price significantly. Rule of thumb: keep trade size under 2% of pool depth to limit slippage below 1%.

Execution cost: Slippage is a direct cost. On a 5 SOL buy, the difference between 0.3% and 3% slippage is real money lost on every entry and exit.

Rug risk detection: Thin liquidity, single pools, unlocked LP tokens, and newly created pools are warning signs. Liquidity analysis catches these before you enter.

Exit planning: Entry liquidity may differ from exit liquidity. If LP is unlocked and owned by one wallet, it can be pulled at any time.

Key Concepts

Total Value Locked (TVL)

Total value of assets deposited in a pool. For a SOL/TOKEN pool with 100 SOL and 1M TOKEN at $0.01 each, TVL = 100 SOL_price + 1M $0.01. TVL alone is insufficient — you need depth at the current price range.

Liquidity Depth

How much can be traded before moving the price X%. In constant-product AMMs, depth is uniform. In concentrated liquidity (CLMM), depth varies by price range — thick near the current price, thin or zero outside active ranges.

Concentration Factor (CLMM)

Concentrated liquidity pools focus capital in a narrow price range, providing deeper liquidity within that range but nothing outside it. A pool with $50K TVL concentrated in a +/-5% range provides the same depth as a $500K constant-product pool within that range, but zero depth beyond it.

Slippage Curve

Slippage is not linear. Plotting slippage against trade size produces a curve that's gentle for small trades and steep for large ones. The shape depends on pool type, TVL, and concentration.

Pool Composition

Who provides liquidity matters. Locked LP tokens cannot be withdrawn (safer). Single-sided liquidity means the pool is imbalanced. Pool age indicates stability — pools older than 7 days with consistent TVL are more reliable.

Data Sources

Four complementary data sources, from free to comprehensive:

See references/data_sources.md for complete endpoint documentation and usage examples.

Core Analysis Pipeline

Step 1: Identify Pools

Fetch all pools for a token. Most Solana tokens have multiple pools across Raydium, Orca, and Meteora.

import httpx

def get_pools(mint: str) -> list[dict]:
    """Fetch all DEX pools for a token from DexScreener."""
    resp = httpx.get(f"https://api.dexscreener.com/tokens/v1/solana/{mint}")
    resp.raise_for_status()
    pairs = resp.json()
    return [p for p in pairs if p.get("liquidity", {}).get("usd", 0) > 0]

Step 2: Measure Depth

For each pool, extract liquidity metrics:

def extract_depth(pool: dict) -> dict:
    """Extract liquidity metrics from a DexScreener pool."""
    return {
        "dex": pool.get("dexId", "unknown"),
        "liquidity_usd": pool.get("liquidity", {}).get("usd", 0),
        "volume_24h": pool.get("volume", {}).get("h24", 0),
        "pool_age_hours": _pool_age_hours(pool.get("pairCreatedAt", 0)),
        "pair_address": pool.get("pairAddress", ""),
    }

Step 3: Estimate Slippage

Use Jupiter quotes at multiple sizes to build an empirical slippage curve. This captures real routing across all pools:

import httpx

SOL_MINT = "So11111111111111111111111111111111111111112"
LAMPORTS = 1_000_000_000

async def estimate_slippage(token_mint: str, sol_amounts: list[float]) -> list[dict]:
    """Query Jupiter for slippage at multiple trade sizes.

    Args:
        token_mint: Token mint address to buy.
        sol_amounts: List of SOL amounts to test (e.g., [0.1, 0.5, 1, 5, 10]).

    Returns:
        List of dicts with sol_amount, output_tokens, price_per_token, slippage_bps.
    """
    results = []
    base_price = None
    async with httpx.AsyncClient() as client:
        for sol in sol_amounts:
            lamports = int(sol * LAMPORTS)
            resp = await client.get(
                "https://api.jup.ag/quote/v1",
                params={
                    "inputMint": SOL_MINT,
                    "outputMint": token_mint,
                    "amount": str(lamports),
                    "slippageBps": 5000,
                },
            )
            if resp.status_code != 200:
                continue
            data = resp.json()
            out_amount = int(data["outAmount"])
            price = sol / out_amount if out_amount > 0 else 0
            if base_price is None:
                base_price = price
            slippage_bps = int((price - base_price) / base_price * 10000) if base_price > 0 else 0
            results.append({
                "sol_amount": sol,
                "output_tokens": out_amount,
                "price_per_token": price,
                "slippage_bps": max(0, slippage_bps),
            })
    return results

Step 4: Assess Concentration

For CLMM pools (Orca Whirlpool, Raydium CLMM, Meteora DLMM), liquidity may be concentrated in a narrow range. Check if the current price is within the active range and how deep liquidity extends:

def assess_concentration(pools: list[dict]) -> dict:
    """Assess concentration risk from pool data."""
    clmm_pools = [p for p in pools if p.get("dexId") in ("raydium", "orca") and "clmm" in p.get("labels", [])]
    cpmm_pools = [p for p in pools if p not in clmm_pools]

    total_clmm = sum(p.get("liquidity", {}).get("usd", 0) for p in clmm_pools)
    total_cpmm = sum(p.get("liquidity", {}).get("usd", 0) for p in cpmm_pools)
    total = total_clmm + total_cpmm

    return {
        "clmm_ratio": total_clmm / total if total > 0 else 0,
        "cpmm_liquidity": total_cpmm,
        "clmm_liquidity": total_clmm,
        "concentration_risk": "high" if total_clmm / total > 0.8 and total > 0 else "low",
    }

Step 5: Compute Liquidity Score

Composite score from 0 (dangerous) to 100 (deep, safe liquidity):

def compute_liquidity_score(
    total_liquidity_usd: float,
    pool_count: int,
    largest_pool_pct: float,
    oldest_pool_hours: float,
    max_slippage_bps_at_1sol: int,
) -> int:
    """Compute composite liquidity score (0-100).

    Components:
        Depth (40%): log-scaled TVL from $1K (0) to $1M+ (40)
        Diversity (15%): more pools = more resilient
        Concentration (15%): penalty if one pool dominates
        Age (15%): older pools are more reliable
        Slippage (15%): lower slippage = better
    """
    import math
    # Depth: 0-40 points
    depth = min(40, int(40 * math.log10(max(total_liquidity_usd, 1)) / 6))

    # Diversity: 0-15 points
    diversity = min(15, pool_count * 3)

    # Concentration: 0-15 points (penalty for single-pool dominance)
    concentration = int(15 * (1 - largest_pool_pct))

    # Age: 0-15 points (7+ days = full marks)
    age = min(15, int(15 * oldest_pool_hours / 168))

    # Slippage: 0-15 points
    slippage = max(0, 15 - max_slippage_bps_at_1sol // 10)

    return max(0, min(100, depth + diversity + concentration + age + slippage))
