optrader

Optrader is a full-scale options trading framework capable of running any customized strategy. It utilizes the TD Ameritrade API to continuously query for option chains for a number of user-defined tickers and option expiration dates, and feeds the data to various 'portfolio managers' that each can run their own strategy and assess entries and exits via signals.

Because the live mode records option chains to a MongoDB instance with an associated sequence number for that day, optrader also supports a 'replay' mode, where if enabled via config, can pull saved option chains (in the order they would have actually arrived from the API) from MongoDb to rerun any strategies locally in less than a minute.

Optrader uses the library sleet to easily and very efficiently retrieve options data from the TD API. It also segregates retrieval of data and the actual processing of data, by utilizing the producer-consumer pattern. Actions are placed in a BlockingQueue to be processing concurrently while retrieving the next set of option chains.

NOTE: This is a generic cut of a private repository that has live working strategies implemented. Figured I can share some of the infrastructure I've used to get to this point. :)

Design

This codebase is mostly Java with touches of Kotlin (mostly experimental, but also to reduce verbosity).

The framework is designed to be very 'plug-and-play' due to the abstractness of the core objects. You can create variations of each type of these objects if desired.

Here's some high level documentation of the structure of the framework -

PortfolioManager:
- An object to maintain a single portfolio (which is really a MongoDb collection of positions)
- A PortfolioManager has the responsibility to re-balance or adjust positions due to constraints of account details/risk metrics
- A PortfolioManager has ONE strategy tied to it
Strategy:
- An object that contains a list of entry and exit signals, and evaluates them to start an entry or exit of a position
- Each strategy is 'run' from its associated PortfolioManager
- Core trading logic is essentially in these classes
Signal:
- Single unit of code that will return true or false depending on if a criteria is met
- There are EntrySignals and ExitSignals, that each take in different arguments
Hedger:
- Role of a hedger is to decide on how to take an extra position to protect the portfolio against downside
- This is typically called upon through a strategy or a portfolio manager
Action:
- An action can be implemented to have logic run at every scan period
- Actions are placed in a processing queue to be executed concurrently in sequence that they are entered
- These are created and called upon in a DataFetcher
DataFetcher:
- A runnable that can retrieve different data from sources
- A LiveDataFetcher will retrieve live data from the TD API
- A ReplayDataFetcher will retrieve saved option chains from a MongoDb instance

The build will spin up a mongo instance on port 27019 and run tests using it, before shutting it down at the end of the build.

Usage

In order to run this program, you must first have an API key. This requires both an account with the TDAmeritrade, and an account setup on the developer page. Once you have the accounts setup, you can create an API key.

You will also need to set up a MongoDb instance, and start it up locally.

The main class takes in a single program argument which is a yaml config file. The main run configuration can be edited to take in ./src/main/resources/config.yml.

An example of what the config.yml would look like- you can create it off of this template and put it in the src/main/resources directory:

credentials:
  apiKey: key
  awsUser: username
  awsPwd: password

email:
  sender: recipient1@email.com
  recipients:
    - recipient1@email.com
    - recipient2@email.com
  eodReportTime: 16:15:00

database:
  host: localhost
  remoteHost: localhost
  port: 27017
  db: dbName

scanner:
  enableReplay: false
  replayDate: 20201130
  batchSize: 10
  strikeCount: 20
  daysToExpirationMax: 100
  timeout: 20
  scanFrequency: 300

tickers:
  - SPY
  - QQQ
  - AAPL

The parameters of the scanner can easily be adjusted to run at a different frequency, retrieve a larger/smaller number of strikes, further out strikes, or a different set of tickers in the config.

To run 'replay', just set enableReplay to 'true', and by default the mongo instance running on localhost will be used to find the historical data. Note that for this to work properly, you should have already run the live fetcher locally through a full day to capture the data. Say you have this application deployed on a external server (AWS, GCP, whatever it may be), you will have to update 'localhost' to the actual server running mongo (and don't forget to authorize or have your IP whitelisted - but these controls are up to you).

database:
  host: localhost
  remoteHost: ec2-XX-XX-XX-XXX.us-east-2.compute.amazonaws.com
  port: 27017
  db: dbName

scanner:
  enableReplay: true
  replayDate: 20201130

If you would like to disable the AWS SES alerting, just remove awsUser and awsPwd from the config, and the program will realize a proper AWS SES service is not configured, and therefore will not send any emails.
