Unable to connect to keosd, if keosd is running please kill the process and try again。 117 | 118 | - 修改 `~/eosio-wallet/config.ini` 中的配置项 `http-server-address`，端口改为8910。 119 | - 设置 config.json 配置文件，修改 `wallet_url` 与上面的端口号一致。 120 | 121 | 3. 连接失败问题，可以忽略。 122 | 123 | ![error_log](https://img.i7years.com/blog/error_log.png) 124 | 125 | 126 | 127 | ## 注意事项 128 | 129 | - 请在可信任设备上部署，一般为自己的电脑，绝对不要部署到阿里云、腾讯云等公有云上，防止私钥被盗。 130 | 131 | - 由于该程序一直在买卖模式间切换，强烈建议**新开一个EOS账户**来配置程序，用作专门的机器人交易账户，以免主账号EOS被一次性买入，造成不必要的财产损失。 132 | 133 | - 请根据自身的风险偏好以及当前RAM价格波动的幅度，合理设置 `buy_ram_by_eos_amount`, `buy_line`, `sell_line`,`max_tx_number` 以免程序不停买入卖出，造成EOS亏损。 134 | 135 | - 由于EOS内存交易会收取0.5%的手续费，因此实际买到的内存数量为: 136 | 137 | ```mathematica 138 | buy_ram_by_eos_amount * (1 - 0.5%) / ram_price 139 | ``` 140 | 141 | 142 | 143 | ## 行情软件 144 | 145 | - http://southex.com/ 146 | - https://eos.feexplorer.io/ 147 | - https://dapp.mytokenpocket.vip/ram/index.html?from=nav_en 148 | 149 | 150 | 151 | ## 免责声明 152 | 153 | - 本程序完全开源，由于自身操作不当造成的任何EOS损失，均与本人无关，请妥善操作。:flushed: 154 | 155 | 156 | 157 | ## 最后 158 | 159 | - 如果对你有所帮助，请给个 Star :stuck_out_tongue: :blush: 160 | -------------------------------------------------------------------------------- /app.js: -------------------------------------------------------------------------------- 1 | /** 2 | * Constant configuration 3 | */ 4 | const config = require('./config/config.json'); 5 | const async = require('async'); 6 | const shell = require('shelljs'); 7 | const log4js = require('log4js'); 8 | const logger = log4js.getLogger("RAM-Robot"); 9 | const log4js_config = require('./config/log4js.json'); 10 | log4js.configure(log4js_config); 11 | 12 | /** 13 | * Eos Client configuration 14 | */ 15 | const Eos = require('eosjs'); 16 | const eosClient = Eos(config.eos); 17 | 18 | const unlock_wallet_cmd = `cleos --wallet-url=${config.keosd.wallet_url} wallet unlock -n ${config.wallet.wallet_name} --password ${config.wallet.password}`; 19 | 20 | shell.exec(`pkill keosd`); 21 | 22 | let count = 0; 23 | setInterval( 24 | function () { 25 | async.parallel( 26 | tasks(), 27 | function (err, results) { 28 | if (count < config.max_tx_number) { 29 | dealResults(results); 30 | } else { 31 | logger.info("Maximum number of transaction pens reached !!!
