I have a problem regarding the calculation of a Raydium pool price. (https://github.com/raydium-io/raydium-sdk)

  1. Raydium API Request for Liquid Pool V4 SOL/USDC.
import { Connection, PublicKey } from "@solana/web3.js";
import { LIQUIDITY_STATE_LAYOUT_V4 } from "@raydium-io/raydium-sdk";
import { BN } from "bn.js"

const SOL_USDC_POOL_ID = "58oQChx4yWmvKdwLLZzBi4ChoCc2fqCUWBkwMihLYQo2"; // Your pool ID

async function parsePoolInfo() {
  const connection = new Connection("https://api.mainnet-beta.solana.com", "recent");
  
  const info = await connection.getAccountInfo(new PublicKey(SOL_USDC_POOL_ID));
  if (!info) return;
  
  // Assuming the structure was successfully decoded
  const poolState = LIQUIDITY_STATE_LAYOUT_V4.decode(info.data);

  console.log(poolState)
}


parsePoolInfo();

Here is where I struggle
3. Calculation of the Price of one SOL. ( 1 SOL / (X) USDC )

**//ATTEMP NUMBER 1:**

// Just for clarification where I got these values!

// from decoded data: Swap Quote Out Amount: 240728976023339, Swap Base Out Amount: 7401612924356853

function calculatePricePerSOLInUSDC(): string {
    return (Number(BigInt("252010786914027")) / Math.pow(10, 6) / (Number(BigInt("7401612924356853")) / Math.pow(10, 9))).toFixed(6);
  }
  
  console.log(`Price per 1 SOL in USDC: ${calculatePricePerSOLInUSDC()}`);


**//ATTEMPT 2**
//Standard calculation of quote amount / base amount
// Got values of these two "VAULTS"
//Base Vault: DQyrAcCrDXQ7NeoqGgDCZwBvWDcYmFCjSb9JtteuvPpz
//Quote Vault: HLmqeL62xR1QoZ1HKKbXRrdN1p3phKpxRMb2VVopvBBz

// at the current timestamp the values are:
//23,177.61 SOL
//5,700,097.46 USDC

5700097.46 / 23177.61 = 245,931

3.1 Output of Calculation (which obviously can´t be right)

**ATTEMPT 1* Price per 1 SOL in USDC: 34.048091
**ATTEMPT 2* Price per 1 SOl in USDC: 245,931

If any additional information is needed please feel free to leave a comment!

This Hybrid AMM pool is sharing idle liquidity with OpenBook, the value in the base and quote vault doesn't account for the orders in the event q of the CLOB.

Divergences between quoteVault and real quote amount can occur.

pool_vault_amount = amm_vault_amount + open_orders.native_coin_total + part_filled_amount - need_take_pnl_coin

You can refer to this program to calculate the amounts in event_q: https://github.com/openbook-dex/program/blob/master/dex/src/state.rs#L2975

Not certain how to interpret, the 34$ result though.

Has any solution been found for this?

We know how to obtain the liquidity of the pool and the market value of those currencies?

Were you able to calculate a price using the swap amounts? I believe you have to fetch the vault amounts and use those...

baseVaultAmount / quoteVaultAmount
