For the moment, we only ran tests, so we never had to connect to the exchange we want to use. Now, let's suppose our strategy is ready to deal with real assets and that we want to use Kucoin.
The first step is to add the right XChange library to your project. It's a bit like adding a JDBC driver. Go to the XChange website, find the corresponding directory. In our case, it's xchange-kucoin directory.
Inside this directory, you have to find the name of the class extending
BaseExchange and implementing
Exchange. In our case, it's org.knowm.xchange.kucoin.KucoinExchange . This name will be used in our
application.properties file for the
Now, we can edit our application configuration located in
src/main/resources/application.properties to change the following properties with the parameters given by the exchange:
cassandre.trading.bot.exchange.driver-class-name=org.knowm.xchange.kucoin.KucoinExchange email@example.com cassandre.trading.bot.exchange.passphrase=cassandre cassandre.trading.bot.exchange.key=61d0c8a041a5330001d0d59c cassandre.trading.bot.exchange.secret=79edb229-a9c8-449d-a476-04689eaf376b
We also have to add the XChange library to our project
pom.xml (the artifactId is Github directory name corresponding to the exchange you chose):
<dependency> <groupId>org.knowm.xchange</groupId> <artifactId>xchange-kucoin</artifactId> <version>5.0.13</version> </dependency>
Last thing, as we are running in production, the two modes (dry & sandbox) must be set to false:
