Make your brokerage work for you.

• Connect to your preferred broker in Kotlin or Java 💁
• Provide a single interface for accessing multiple brokers’ APIs 🏪
• Accelerate the development of algorithmic trading for the JVM 💰

Before you bring Batil into your own project you’ll want to first retrieve your credentials from your broker and setup Docker. Then add the dependency to your Gradle file.

build.gradle.kts

repositories {
    mavenCentral()
}

dependencies {
    implementation("com.seansoper:batil:^1.0.4")
}

You can then use the full-suite of service endpoints.

val client = EtradeClient(
                "key",
                "secret",
                "username",
                "password",
                EtradeClient.Endpoint.LIVE)

client.accounts.list()?.let {
    it.first().accountIdKey?.let { accountIdKey ->
        val service = client.orders
        val previewRequest = buyEquityLimit("PLTR", 21f, 100)

        service.createPreview(accountIdKey, previewRequest)?.let { previewOrderResponse ->
            service.placeOrder(accountIdKey, previewRequest, previewOrderResponse)?.let { completedOrder ->
                println("Purchased 100 shares of PLTR at $21")
                println(completedOrder)
            }
        }
    }
}

You’ll need to request both a sandbox and production API consumer key and secret from the API team.

• Sign into your E*TRADE account and head over to Customer Service ➡ Message Center ➡ Contact Us. From there select the account you want to associate with your API key. For the subject, select API Sandbox Auto and for the topic select Sandbox Key. Expect to hear back within a few hours.
• To access the production API you’ll need to send a signed copy of the Developer Agreement to [email protected].

Docker is used to access a Chromium instance that can login to the E*TRADE website to retrieve the necessary OAuth keys.

• Download Docker
• Run the following command to start the container:

docker container run -d -p 9222:9222 zenika/alpine-chrome \
--no-sandbox \
--remote-debugging-address=0.0.0.0 \
--remote-debugging-port=9222 \
--user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36" \

• You can clone the project locally and build the demo E*TRADE client (check the build/libs dir).

./gradlew fatJar

• Using the sample provided, add a batil.yaml to the directory where you intend to run the JAR file. Substitute the default values with the correct values.
• Important Ensure you never check your version of batil.yaml into git.
• Verify your account.

java -jar Batil-etrade.jar verify

• By default the app runs in sandbox mode. Add the --production switch to use in production.
