    ThetaGang is an IBKR trading bot for collecting premiums 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. 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). This strategy reduces risk, but may also limit gains from big market swings. By reducing risk, one can increase leverage. 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.

Guide to Open Source API Gateways

An open source API gateway is a type of software that acts as a middleman between the back-end systems and other services, applications, and users. It handles incoming requests from clients and routes them to the appropriate backend service for processing. The gateway then takes the processed data from the backend service before routing it back to the client. An open source API gateway is an ideal solution for organizations that need to provide access to their services, but lack the resources or infrastructure needed for a fully-fledged commercial product.

Open source API gateways are usually built using serverless computing architectures such as Amazon Lambda, Apache OpenWhisk, or Google Cloud Functions. This allows organizations to quickly deploy their application without having to deal with complex hardware or software setups. Once deployed, they can be customized with filters and plugins like rate limiting and authentication which can help protect against malicious traffic. Other features like caching and queuing can increase scalability by reducing response times when multiple clients are accessing the same resource.

The benefits of an open source API gateway include being able to take full control over implementation details while still reaping the benefits of pre-built components like serverless computing architecture. This makes it easier to create custom APIs that can be tailored to specific business needs while avoiding vendor lock-in associated with proprietary solutions. Additionally, open source API gateways are generally more cost effective than their closed-source counterparts as there are typically no fees associated with use or customization of these tools.

Overall, open source API gateways provide businesses with an efficient solution for managing external access points by providing all of the necessary components required for building custom APIs at a much lower cost than traditional approaches require. With additional features like rate limiting and authentication available on most platforms out of the box, they also offer significant advantages in terms of security compared to more traditional solutions as well.

Features Provided by Open Source API Gateways

  • Rate Limiting: Open source API gateways provide rate-limiting capabilities which allow for the monitoring and control of traffic hitting the APIs. This is set to ensure that excessive requests don’t overwhelm or compromise the service.
  • Authentication: Open source API gateways offer authentication services to ensure that only authorized users are accessing the gateway. This includes enabling user-based verification, client credentials, and other methods of authentication for added security.
  • Authorization: Along with authentication, open source API gateways provide authorization services that define who can access certain resources/APIs within a system as well as what kind of operations they are able to perform on them.
  • Caching: Caching is an important part of improving performance in any application environment, and open source API gateways support caching capabilities such as local caching, distributed caching, and third-party cache integration (e.g., Redis).
  • Throttling & Load Balancing: These features not only help maintain application stability by reducing latency but also help distribute the incoming load evenly across different nodes in a clustered architecture (load balancing) while limiting the number of requests made against an endpoint within a given time period (throttling).
  • Protocol Translation & Transformation: For heterogeneous environments where applications may need to communicate with each other using different protocols or formats, open source API Gateways are able to bridge this gap by providing protocol translation/translation services so data can be exchanged in various formats based on context requirements.
  • Monitoring & Logging Services: To debug issues quickly and effectively during runtime, open source API Gateways offer various levels of visibility into how each service behaves so developers can easily identify misuse or problems at any time through logging services or collecting metrics from all connected endpoints/services running on their platform; helping organizations improve their overall experience with analytics & intelligence insights.

What Types of Open Source API Gateways Are There?

  • Reverse Proxy API Gateway: A Reverse Proxy API gateway acts as an intermediary between a client and a server to intercept and filter requests for improved security, traffic management, scalability, and availability. It is typically deployed on the edge of a network and acts as a single point of entry for clients requesting access to multiple services or backends.
  • Microservices API Gateway: A Microservices API gateway allows communication between distributed microservice applications. It enables developers to route application requests based on specific system requirements such as latency or performance optimization.
  • Web Application Firewall (WAF) API Gateway: A WAF API gateway adds a layer of protection to prevent malicious attacks when handling sensitive data within web applications. This type of gateway also has features including rate limiting and DDOS protection capabilities to restrict untrusted traffic from accessing an application or backend resource.
  • ESB/SOA-based API Gateway: An ESB (Enterprise Service Bus)/SOA (Service Oriented Architecture)-based API gateway facilitates interoperability among heterogenous systems responsible for Enterprise Application Integration(EAI). It provides secure specialized message processing capabilities and routing support for service orchestration.
  • Multicloud API Gateways: Multicloud API gateways enable developers to integrate services hosted in public cloud providers like AWS, GCP, Azure, etc.; with their private cloud environments using various protocols such as REST APIs over HTTP connections, SAML SSOs (Security Assertion Markup Language), JWT tokens, etc. They ensure efficient operations across multiple hybrid cloud architectures through unified authentication schemes along with managing broken connections due failovers without impacting the service availability.
  • API Management Platforms: An API management platform provides an end-to-end solution for developers to securely manage and monitor their applications. It helps in breaking up a large application into smaller services and provides essential features such as analytics, scalability, authentication, authorization & security measures, etc. It also simplifies debugging and troubleshooting efforts by providing analytic insights regarding the performance of the application components along with access logs to identify any malicious activities or abnormalities.
  • IoT API Gateways: An IoT (Internet of Things) API gateway is designed to enable communication between a distributed network of connected devices used in industrial applications such as smart homes, healthcare systems and manufacturing automation. It orchestrates complex data exchange operations by providing message transformation, semantic understanding, protocol conversion support, etc. It also helps in ensuring secure authentication for access within the integrated system along with monitoring activities to detect malicious intrusion attempts.

Benefits of Using Open Source API Gateways

  • Cost Savings: Open source API gateways are typically free, meaning companies do not incur expensive licensing fees. This makes it more accessible and cost-effective to organizations than proprietary APIs.
  • Flexibility: Open sources APIs allow developers to customize and modify their gateway as needed. This means that it can be adapted to meet specific requirements or provide additional features depending on the application’s needs.
  • Scalability: The open source framework offers higher scalability compared to commercial alternatives because there is no need for re-purchasing of licenses when adding usage or new users. It also supports large scale projects as the community works together towards its development.
  • Independent Development: An important advantage in using an open source API platform is that a single development team does not own it or direct how it should be used, but instead many people from different places work together on its improvement and expansion. This allows companies to have full control over their api applications without having to depend on a third party.
  • Community Support: Open source provides access to an extensive and ever growing community of developers who can offer assistance with technical questions, bug fixing and more. Ultimately, leading faster product improvements at lower costs than what would otherwise be available with a closed source ecosystem.
  • Security: Open source API gateways also provide better security, as there is a larger pool of developers who can help find and fix potential vulnerabilities. Open source APIs are constantly monitored and tested by the community, allowing users to have confidence in their data protection.

Who Uses Open Source API Gateways?

  • Developers: Developers are the main users of open source API gateways. They're responsible for designing, building, and maintaining the APIs. They need to understand how to configure and deploy the gateway as well as use its features.
  • System Administrators: System administrators are in charge of configuring, monitoring, and maintaining the gateway on a daily basis. They also have to be knowledgeable about the different types of services offered by the gateway and how they interact with other systems.
  • Quality Assurance Professionals: Quality assurance professionals verify that all components of an API work correctly before it is put into production. They must ensure that there are no bugs or security vulnerabilities present in an API that could affect its functionality or performance.
  • Security Specialists: Security specialists are responsible for creating secure endpoints with authentication credentials that prevent unauthorized access from outside sources. They must be familiar with encryption protocols and methods used by open source gateways in order to protect sensitive data from being accessed without permission.
  • Business Analysts: Business analysts analyze data gathered from open source APIs to determine how they can best serve their company's needs. For example, they can track usage patterns or investigate ways to reduce costs associated with usage fees incurred when using cloud-based processes connected via a gateway interface.
  • Database Administrators: Database administrators rely on open source APIs to manage database connections necessary for applications running behind gateways such as MySQL databases or NoSQL databases like MongoDB or Cassandra clusters. They must understand the various connection types available and be knowledgeable about data formats that are supported by an API gateway.
  • Technical Writers: Technical writers use open source APIs to generate technical documentation such as user guides, FAQs, release notes, and more. They need to understand how the components of a gateway interact with each other in order to accurately document its features for end users.

How Much Do Open Source API Gateways Cost?

Open source API gateways often come with no upfront cost, allowing developers to use them without paying any fees. However, the costs associated with open source API gateways may include things such as hosting and maintenance costs, depending on the size and complexity of your project. If you intend to use an open source API gateway for a large-scale enterprise application, it is important to factor in these potential additional costs into your overall budget. While open source solutions offer many advantages such as being free from license restrictions or platform-specific dependencies, they also tend to require more time and effort when it comes to setting up and managing them than commercial alternatives. Further, if you are aiming for high scalability of an implementation, most open source solutions might not be able to meet your needs due to limitations in features or support for different formats. As a result, one must carefully consider their own specific requirements before deciding whether an open source solution would be suitable for their project.

What Do Open Source API Gateways Integrate With?

Open source API gateways can be integrated with many types of software applications. These include web services, cloud-based applications, client-server applications, mobile apps, and machine learning systems. Web services often need to integrate with external sources to access data or functionality, and an open source API gateway provides the necessary security and functionality needed to do so. Cloud-based applications can also benefit from an open source API gateway due to its scalability and flexibility when dealing with large datasets. Client-server applications typically require a secure connection between the server and client in order to communicate effectively; an open source API gateway provides this connection without any additional costs for commercial solutions. Mobile app development is also becoming increasingly reliant on external APIs as more users switch from desktop computers to mobile devices; an open source API gateway allows developers to securely connect their apps to these resources without incurring additional costs. Lastly, data scientists are using machine learning systems that require integration with specific datasets; through the use of an open source API gateway they can utilize these datasets in their models without having worry about compromising their integrity or security.

Getting Started With Open Source API Gateways

Getting started with open source API Gateways doesn’t have to be intimidating. There are many easy-to-use tools, libraries, and frameworks out there that can help you get your project up and running quickly.

The first step to getting started is determining what type of gateway you need for your application. Do you need a light-weight gateway for simple APIs? Or something more robust for complex systems? Knowing this will help narrow down the range of gateways available to choose from.

Once you’ve decided on the type of gateway needed, it’s time to start shopping around for one that fits your needs and budget. Popular open source gateways include Kong, Apigee Edge, Zuul, Tyk, and Spring Cloud Gateway—all offer different features that may meet yours specific requirements.

Once you’ve selected a gateway it’s time to install it on your server or cloud platform of choice (e.g., Amazon Web Services or Microsoft Azure) so that it can be deployed into production environments. Installing a gateway typically involves downloading the appropriate packages, configuring back end services such as databases or caches and setting up authentication/authorization mechanisms such as Oauth2 or JWT tokens in order to manage user access control privileges. Depending on the complexity of the project this process can take some time but should not require any advanced coding skills if done correctly.

Finally its time set up routes within the gateway; allowing requests from clients to reach their respective servers in an efficient manner whilst also ensuring client security by implementing strict filters on incoming/outgoing messages based upon certain rules set by developers in advance e.g denying unauthorized requests before they can even attempt reaching their destination servers beside other measures like enforcing rate limits per user or IP address, etc. Setting up routes should involve minimal coding effort using some language depending upon type of request (such as JavaScript for web applications).

Once everything is properly configured you will be ready to deploy your API gateway into production environment. Don’t forget to make sure your gateway is secured by regularly checking for vulnerabilities and patching up any holes where needed.
