Θ ThetaGang Θ

ThetaGang is an IBKR trading bot for collecting premium by selling options using “The Wheel” strategy. The Wheel is a strategy that surfaced on Reddit, but has been used by many in the past. This bot implements a slightly modified version of The Wheel, with my own personal tweaks.

I’ve been streaming most of the work on this project on Twitch, so follow me over there.

How it works

You should start by reading the Reddit post to get some background.

The strategy, as implemented here, does a few things differently from the one described in the post above. For one, it’s intended to be used to augment a typical index-fund based portfolio with specific asset allocations. For example, you might want to use a 60/40 portfolio with SPY (S&P500 fund) and TLT (20 year treasury fund).

The main difference between ThetaGang and simply buying and holding index funds is that this script will attempt to harvest volatility by selling options, rather than buying shares directly. This works because implied volatility is typically higher than realized volatility on average. Instead of buying shares, you write puts. This has pros and cons, which are outside the scope of this README.

You could use this tool on individual stocks, but I personally don’t recommend it because I am not smart enough to understand which stocks to buy. That’s why I just buy index funds.

ThetaGang will try to acquire your desired allocation of each stock or ETF according to the weights you specify in the config. To acquire the positions, the script will write puts when conditions are met (adequate buying power, acceptable contracts are available, enough shares needed, etc).

ThetaGang will continue to roll any open option positions indefinitely, with the only exception being ITM puts. Once puts are in the money, they will be ignored until they expire and are execised (after which you will own the underlying).

Please note: this strategy is based on the assumption that implied volatility is, on average, always higher than realized volatility. In cases where this is not true, this strategy will cause you to lose money.

In the case of deep ITM calls, the bot will prefer to roll the calls to next expiration rather than allowing the underlying to get called away. If you don’t have adequate buying power available in your account, it’s possible that the options may get exercised instead of rolling forward and the process starts back at the beginning. Please keep in mind this may have tax implications, but that is outside the scope of this README.

In normal usage, you would run the script as a cronjob on a daily, weekly, or monthly basis according to your preferences. Running more frequently than daily is not recommended, but the choice is yours.

Project status

This project is, in its current state, considered to be complete. I’m open to contributions, but I am unlikely to accept PRs or feature requests that involve significant changes to the underlying algorithm.

If you find something that you think is a bug, or some other issue, please create a new issue.

Requirements

The bot is based on the ib_insync library, and uses IBC for managing the API gateway.

To use the bot, you’ll need an Interactive Brokers account with a working installation of IBC. If you want to modify the bot, you’ll need an installation of Python 3.8 or newer with the poetry package manager.

One more thing: to run this on a live account, you’ll require enough capital to purchase at least 100 shares of the stocks or ETFs you choose. For example, if SPY is trading at $300/share you’d need $30,000 available. You can search for lower priced alternatives, but these tend to have low volume on options which may not be appropriate for this strategy. You should generally avoid low volume ETFs/stocks. If you don’t have that kind of capital, you’ll need to keep renting out your time to the capitalists until you can become a capitalist yourself. That’s the way the pyramid scheme we call capitalism works.

Installation

Before running ThetaGang, you should set up an IBKR paper account to test the code.

$ pip install thetagang

It’s recommended you familiarize yourself with IBC so you know how it works. You’ll need to know how to configure the various knows and settings, and make sure things like API ports are configured correctly. If you don’t want to mess around too much, consider running ThetaGang with Docker.

Usage

$ thetagang -h

Running with Docker

My preferred way for running ThetaGang is to use a cronjob to execute Docker commands. I’ve built a Docker image as part of this project, which you can use with your installation. There’s a prebuilt Docker image here.

To run ThetaGang within Docker, you’ll need to pass config.ini for IBC configuration and thetagang.toml for ThetaGang. There’s a sample ibc-config.ini included in this repo for your convenience.

The easiest way to get the config files into the container is by mounting a volume. For example, you can use the following command:

$ docker run --rm -it \
    -v ~/ibc:/ibc \
    brndnmtthws/thetagang:latest \
    --config /ibc/thetagang.toml

Development

Check out the code to your local machine and install the Python dependencies:

$ poetry install
$ poetry run autohooks activate
$ poetry run thetaging -h
...

You are now ready to make a splash! 🐳
