#### Get the Exchange Price in the Pool

As we explained before, when we use the token address (there are two: tokenIn and tokenOut) and the rate setting, we can get the exchange pool (smart contract) address of this exchange portfolio from the ```getPool``` method of the ```Factory``` contract of ```Uniswap```.
Once the pool address is obtained, the ABI of the pool contract is registered and the ```slot0``` method of the pool contract can be called to get the data related to the current exchange price and further resolve the exchange price.

Uniswap V3 트레이딩 라이브러리를 사용하세요

이$.testUniswap()이 템플릿의 함수는 템플릿의 기능을 테스트하는 함수이며, 그 코드는 템플릿 호출을 사용하는 방법을 보여줍니다.

$.testUniswap = function() {
    let ex = $.NewUniswapV3()
    Log("walletAddress: ", ex.walletAddress)
    let tokenAddressMap = {
        "USDT": "0xdac17f958d2ee523a2206206994597c13d831ec7",
        "1INCH": "0x111111111117dC0aa78b770fA6A738034120C302",

    }
    for (let name in tokenAddressMap) {
        ex.addToken(name, tokenAddressMap[name])
    }

    Log(ex.getPrice('ETH_USDT'))
    Log(ex.getPrice('1INCH_USDT'))

    // swap 0.01 ETH to USDT
    Log(ex.swapToken('ETH', 0.01, 'USDT'))
    let usdtBalance = ex.balanceOf('USDT')
    Log("balance of USDT", usdtBalance)

    // swap USDT to DAI then DAI to ETH
    Log(ex.swapToken('USDT', usdtBalance, 'DAI,ETH'))

    Log("balance of ETH", ex.getETHBalance())

    // Log(ex.sendETH('0x11111', 0.02))
    
    // ...
}

이벤트 검색

이 섹션에서는 FMZ 퀀트 트레이딩 플랫폼을 사용하여 스마트 계약에 의해 출시되는 이벤트를 읽는 법을 배우게됩니다. 스마트 계약에 의해 출시되는 이벤트는 이더리움 가상 머신의 로그에 저장됩니다.

eth_getLogs

스마트 계약 발매 이벤트를 검색하려면 Ethereum의 RPC 방법을 사용해야 합니다.eth_getLogs이더리움 RPC 노드를 호출하는 방법에 대해 예를 들어,WETH계약자는 FMZ를 사용하여 코드를 작성하고 테스트 할 수 있습니다.디버깅 도구, 교환 객체에 의해 구성된 RPC 노드는 이더리움 메인넷 노드이며,eth_getLogs방법, 우리는 세 개의 매개 변수를 지정fromBlock, toBlock, address, 우리는 fromBlock와 toBlock 매개 변수를 사용하여 블록 내의 데이터로 질의를 제한합니다:

function toAmount(s, decimals) {
    return Number((BigDecimal(BigInt(s)) / BigDecimal(Math.pow(10, decimals))).toString())
}
function toInnerAmount(n, decimals) {
    return (BigDecimal(n) * BigDecimal(Math.pow(10, decimals))).toFixed(0)
}
function main() {
    // getBlockNumber
    var blockNumber = exchange.IO("api", "eth", "eth_blockNumber")
    Log("blockNumber:", blockNumber)

    // get logs
    var fromBlock = "0x" + (toAmount(blockNumber, 0) - 1).toString(16)
    var toBlock = "0x" + toAmount(blockNumber, 0).toString(16)
    var params = {
        "fromBlock" : fromBlock,
        "toBlock" : toBlock,
        "address" : "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2"   // Address of WETH contract
    }
    var logs = exchange.IO("api", "eth", "eth_getLogs", params)

    // Due to the large amount of data, if you use the Log function to print, the data will be truncated. Use return to return the complete data in the "Function Result" edit box on the page
    return logs   
}

로그 데이터를 얻었고, 많은 내용으로 인해 일부를 생략했습니다.
