Tinkoff Invest Robot

It is an application that automatically trades at the Tinkoff broker using Tinkoff Invest API. It supports multiple accounts and multiple strategies per account.

Strategies

Robot uses strategies to trade. A strategy can be configured with the next parameters:

  • tinkoffAccountId: id of the account to trade;
  • sandbox: flag is the account real or at the sandbox;
  • type: type of strategy (see supported types below);
  • executionPeriod: how often the strategy will be executed;
  • instruments: array of instrument (FIGI) to use in strategy.

Each strategy is periodically executed. During its execution it may create some orders to buy or to sell securities according to its logic.

Current implementation supports the next strategies:

  • INVEST_FREE_CASH_EQUAL_WEIGHTED
  • REBALANCE_EQUAL_WEIGHTED

INVEST_FREE_CASH_EQUAL_WEIGHTED strategy

This is an investing strategy that periodically checks if there is a free cash at the account and uses this free cash to buy the specified securities using the Equal-Weighted approach. This strategy does not sell anything and only invests free cash that can be added using recurrent auto-replenishment feature of Tinkoff broker. It is expected that this strategy is run on a regular basis, e.g. daily, weekly or monthly.

REBALANCE_EQUAL_WEIGHTED strategy

This strategy sells and buys securities to make the portfolio of securities equally weighted. It is expected that this strategy is run on a regular basis but rarely, e.g. quarterly or less frequently.

Executions and orders

Robot creates a strategy execution (StrategyExecution) when it understands that the strategy must be executed according to its executionPeriod parameter. The strategy execution may create one or more orders according to the strategy logic. A strategy execution processor tracks the progress of the execution and the status of orders, and finally ends the execution.

Build and Run

Recommended start

The application is expected to run with a standalone PostgreSQL server. The next environment variables are required for the application:

  • POSTGRES_HOST: PostgreSQL server hostname
  • POSTGRES_PORT: PostgreSQL server port
  • POSTGRES_DBNAME: database name in PostgreSQL server
  • POSTGRES_USERNAME: user name in PostgreSQL server
  • POSTGRES_PASSWORD: user password in PostgreSQL server
  • TINKOFF_CLIENT_TOKEN: required if interaction with real accounts is expected
  • TINKOFF_CLIENT_SANDBOX_TOKEN: required if interaction with sandbox accounts is expected
  • TINKOFF_CLIENT_APP_NAME: optional, to distinguish API requests

The command to run the application:

mvnw spring-boot:run

[Tinkoff Contest Case] Start with inmemory database using testcontainers

This application was developed for Tinkoff Invest Robot Contest. One of the requirements was to run the application without extra applications. So it is possible to run the application without standalone PostgreSQL server. To run the application with PostgreSQL server running in Docker (using testcontainers) only the next environment variables must be set:

  • TINKOFF_CLIENT_TOKEN: required if interaction with real accounts is expected
  • TINKOFF_CLIENT_SANDBOX_TOKEN: required if interaction with sandbox accounts is expected
  • TINKOFF_CLIENT_APP_NAME: optional, to distinguish API requests

The command to run the application:

mvnw spring-boot:run -D"spring-boot.run.profiles"=inmemory

Pay attention that no data is saved between restarts of the application in this mode.

REST API

REST API allows to configure the robot and to get details about its operation. REST clients can be used to visualize results of strategies: print strategy executions and created orders with their statuses (see Testing section below for details and demonstration).

OpenAPI 3 specification docs are available at the path /v3/api-docs/ (http://localhost:8080/v3/api-docs/).

Swagger UI is available at the path /swagger-ui.html (http://localhost:8080/swagger-ui.html).

Testing

This section presents the usage of the robot with a real account. For testing purposes the executionPeriod is set to 10 minutes. Let's create the first strategy of INVEST_FREE_CASH_EQUAL_WEIGHTED type:

If the orders are not filled immediately then the service checks periodically the status of orders until they are filled. Since all orders are in final status (FILLED) the executions is ended (endedAt is not null).

Let's add more money and check that robot buys more securities. The executions:

Let's archive (stop) the first strategy, so it does not affect the testing of the next strategy (Actually, multiple strategies can be active on a single account. There is an internal constraint that verifies that exactly one execution is active on a single account at any moment so that strategies do not affect each other). The REST API call:

curl -X POST 'localhost:8080/api/v1/strategies/fe003d61-d044-42e1-8e89-d2785b690ea2/archive'

    ]
}

Now let's create the second strategy of REBALANCE_EQUAL_WEIGHTED type:

curl --location --request POST 'localhost:8080/api/v1/strategies' 
curl -X POST 'localhost:8080/api/v1/strategies' \

        "BBG004730JJ5"
    ]
}

It was executed without orders since our account is balanced due to prices not changed seriously:

Let's add some money and buy 9 lots of security BBG004731354 using the mobile app so the positions on account are not balanced. After some time the strategy execution is created and processed.

The orders to sell the excess of security are placed and filled. After that free money are used to buy other securities so that the positions are balanced according to the strategy.

Next steps

  1. More strategies can be implemented. For example, it is a popular approach to use market capitalization weighed algorithm to calculate the weight of a security in the portfolio instead of equally weighted. This approach will be easy to implement when market capitalization information will be added to Tinkoff API.
  2. Tune parameters of execution. Current parameters were chosen for easy testing but in real world scenarios executions can be created more rarely but database queue tasks may be invoked more frequently to improve responsiveness.
  3. Tokens are supported per application at the moment. But it is better to use different tokens for different accounts. This can be part of application configuration as well as runtime parameters of strategies.
  4. Strategies can be improved to work with multiple accounts even from different brokers. The model must be extended and a new API clients must be added.
