Alternatively, you can use X Virtual Frame Buffer (xvfb) [See Details][npmforever] ```js const {metaMask, trader, token} = require('crypto-bot-trader'); const Xvfb = require('xvfb'); (async function() { let xvfb = new Xvfb(); xvfb.startSync(); // // initiate await metaMask.build(); const initiatedTrader = new trader({metamask_with_build: metaMask, token: token}); await initiatedTrader.analyzeMarket() setInterval(async () => { await initiatedTrader.analyzeMarket() }, 300000); // every 5 minutes })(); ``` ## Deploy in cloud server Setup in cloud server, A simple CLI tool for ensuring that a given script runs continuously/in-background called (forever) [See Details][npmforever] ```js const {metaMask, trader, token} = require('crypto-bot-trader'); const { exec } = require("child_process"); (async function() { await metaMask.initializeSecurity({pwd: null, is_setup: true}); exec(`forever start headless.js --pwd=1`, (error, stdout, stderr) => {}); })(); ``` ## Focus Feature Focus on a specific token, this is good especially if the volatility of token is really high. - focus on matic? wmatic - focus on bitcoin? wbtc - foucus on etherium? weth ```bash node {jsFile} --focus=wmatic ``` [erc20]: https://etherscan.io/tokens [erc20List]: https://github.com/marcelooblan2016/crypto-bot-trader/blob/main/src/Records/Migrations/tokenContracts.js [npmforever]: https://www.npmjs.com/package/forever [npmxvfb]: https://www.npmjs.com/package/xvfb ## Method: 'sendto' After a successful trade, profit will be sent to a specific wallet address. This feature is good if you have bunch of bot traders & you want the profit to be centralized. ```bash node {jsFile} --focus=wmatic --method=sendto ``` In .env in {root} ```bash WALLET_ADDRESS= # Exact amount that will be the baseline of trader to prevent draining of wallet; (USDC Currency) # Ex: 200 BASE_AMOUNT= ``` --- _Source: https://npm.io/package/crypto-bot-trader · Machine-readable twin of the npm.io package page.
