Launch Example

robot

The robot uses stop-loss/take-profit strategy. User can configure robot by setting market, price and size. After robot is successfully started, it listens on 1-minute candles (via websocket subscription), compares the average candle price with user settings and sends ioc order on Kraken if the price is triggered.
The robot can be launched on several markets in parallel.
For conditions of robot start see /start or /startall endpoint.
Afer user configured inner robot order (/setsell or /setbuy) this order becomes active. If this order is trigged (sended to Kraken) or explicitly cancelled by the user (/unset...), it becomes inactive.
User can set a new order (e.g. set buy order if it was not set at startup), change the price and size in an already active one or cancel the order when the robot is already running on market (no need to stop the robot especially for that).
The robot sends notifications to Telegram bot (see notifications).
Information about executed orders is stored in Postgres.

setup

Parameters must be set as environmental variables (you can use source setenv.sh for convenience).

APIPublic   - public API-key from Kraken demo-platform
API Private - private API-key from Kraken demo-platform
TgChatID    - Telegram bot chat ID
TgBotURL    - https://api.telegram.org/bot[token]/sendMessage
port        - port on which the robot server will run
dsn         - string for connecting to Postgres

Use docker-compose.yaml to start Postgres.

Some Makefile rules:

make - start robot server
make test - run tests with coverage

notifications

✅ Start subscription on market: pi_ethusd

The robot is successfuly started on market.

Websocket error (code 1006) and reconnection doesn't help.
Server is stopped (graceful shutdown).

📌 Make buy order on pi_xbtusd. Price: 58620.50

Order was successfuly placed and executed.

❌ Fail to place order: pi_ethusd: sell: server error

Fail to send order to Kraken due to inner error.

❌ Fail to execute order: pi_xbtusd: sell: insufficient funds

Order was rejected because of balance error.

❌ Fail to execute order: pi_xbtusd: sell

Order was rejected because of every another reason except balance error.
