Need help filtering solana transactions from QuickNode streams. Extracting amount of SOL sent and direction of swap

Im currently trying to build a whale transaction monitor. I have a QuickNode stream setup that is feeding me live Solana tx's. It gives me raw payload block data that I have the ability to filter down and only receive transactions that fit my requirements.

Currently, I filtered down transactions that involve the raydium AMM v4 liquidity pool Program ID in the instructions along with the targeted token address I want to track.

I have been having a hard time trying to figure out the amount of SOL being sent for the swap and which direction the swap is occuring.

I essentially want to be able to print out basic info about the trade like it says on SOL scan. "Wallet1 swapped 100 SOL for 344876 Pnut"

here is the current code for my QuickNode stream filter. Thank you!

function main(stream) {    try {        const incomingData = stream.data ? stream.data : stream;        const blocks = Array.isArray(incomingData) ? incomingData : [incomingData];        const filteredTransactions = [];        // Define the mint address you want to track        const TARGET_MINT = "2qEHjDLDLbuBgRYvsxhc5D6uDWAivNFZGan56P1tpump"; // Pnut        // Define Raydium's program ID(s)        const RAYDIUM_PROGRAM_IDS = ["675kPX9MHTjS2zt1qfr1NYHuzeLXfQM9H24wFSUt1Mp8" // Raydium AMM v4        ];        blocks.forEach(block => {            if (!block.transactions || !Array.isArray(block.transactions)) {                return;            }            block.transactions.forEach(transaction => {                // Get pre and post token balances                const preTokenBalances = transaction.meta.preTokenBalances || [];                const postTokenBalances = transaction.meta.postTokenBalances || [];                // Check if transaction involves our target mint                const involvesMint = [...preTokenBalances, ...postTokenBalances].some(                    balance => balance.mint === TARGET_MINT                );                // Check if transaction was successful                const isSuccessful = transaction.meta.status?.Ok === null;                // Check if transaction involves Raydium's program ID                const involvesRaydium = transaction.transaction.message.instructions.some(                    instruction => RAYDIUM_PROGRAM_IDS.includes(instruction.programId)                );                // Convert all balances from lamports to SOL                const preBalances = transaction.meta.preBalances.map(balance => balance * 1e-9);                const postBalances = transaction.meta.postBalances.map(balance => balance * 1e-9);                // Calculate differences between post and pre balances                const balanceDifferences = postBalances.map((post, index) => post - preBalances[index]);                // calculates the difference between the pre and post balance                // const difference = postSolbalance - preSolbalance;                // filters transactions based on the criteria, account bought more SOL than the threshold                if (involvesMint && isSuccessful && involvesRaydium) {                    filteredTransactions.push({                        preSolbalance: preBalances,                        postSolbalance: postBalances,                        balanceDifferences: balanceDifferences,                        transaction: transaction                    });                }            });        });        if (filteredTransactions.length === 0) {            return null;        }        return { transactions: filteredTransactions };    } catch (error) {        return { error: error.message };    }}// Utility function to decode Base58-encoded strings into byte arraysfunction decodeBase58(encoded) {    const BASE58_ALPHABET = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz";    const result = [];    for (let i = 0; i < encoded.length; i++) {        let carry = BASE58_ALPHABET.indexOf(encoded[i]);        if (carry < 0) return []; // Invalid character        for (let j = 0; j < result.length; j++) {            carry += result[j] * 58;            result[j] = carry & 0xff;            carry >>= 8;        }        while (carry > 0) {            result.push(carry & 0xff);            carry >>= 8;        }    }    for (let i = 0; i < encoded.length && encoded[i] === "1"; i++) {        result.push(0);    }    return result.reverse();}

Here is the filtered transaction data that QuickNode returns, you can see the fields I pushed to the return object along with the raw transaction data that I also added to it for you to see and examine.
