Example of config file::
{
"wsPort": 2345,
"exchange": "tidex",
"apiKey": "UFRFIREFONREIVONREIOVNREOVRENVINO",
"apiSecret": "vgyewjnimkoxoerjnbhcxkoeijnhvbijnkmwnrjhevbjcn",
"ipArray": [
"192.32.32.12",
"173.32.45.34"
]
}Install and run
Installation:
yarn --prodRun:
cross-env CONFIG_FILE_PATH='<config_file_path>' node index.jsOr:
yarn run start-bibox
yarn run start-binance
yarn run start-bitfinex
yarn run start-huobi
yarn run start-tidex
yarn run start-okexInteraction format
All requests to the ws should have json format:
{
"action": "<method name>",
"params": <parameters>
}Responses also will be in json:
{
"success": true or false
"event": string with event name
"action": string with method name. Will be in response only after client's actions.
"data": data object
"timestampStart": timestamp of event excecution start

}Possible events:

After opening a connection with ws server will send two messages: connected и availableActions. After that server will wait command from client.
