Recently, I decided to embark on a DIY Powerwall project for my house. The first challenge I faced was determining the appropriate size for the system. Living in Arizona, where APS and SRP are the primary utilities, my goal was to eliminate or shift peak demand. Specifically, I aimed to build a battery that discharges between the peak hours of 2 PM to 8 PM and recharges at night when energy is less expensive.
Why Build a DIY Powerwall?
The primary reason for this project is that demand charges and peak energy costs are incredibly expensive. SRP’s peak demand charges are calculated by breaking down your entire month into 30-minute increments. They then determine the highest 30-minute increment of kW usage for that month and apply it to the chart below to determine your peak demand cost. This cost is a one-time charge applied to your monthly bill but can be significant.
In addition to peak demand costs, you still have to pay per kWh for on-peak and off-peak usage. Here is the breakdown of SRP’s E27 plan:
You can see the prices above are a lot cheaper than SRP’s traditional plan
Winter 42% cheaper
Summer 58% cheaper
Summer peak 56% cheaper
Understanding the Costs
The prices on the E27 plan are significantly lower than SRP’s traditional plan. However, to achieve these savings, you need to shift your electricity usage to off-peak hours. If you don’t offset your 2 PM to 8 PM usage on this plan, you will incur substantial demand charges, which can easily exceed $1,000 in a single month. This highlights the importance of avoiding peak demand charges to benefit from cheaper electricity rates.
The Goal
Our objective is to eliminate electricity usage from 2 PM to 8 PM by discharging a battery and then recharging it at night. The next step is to determine how much energy I have historically used during these hours.
Recently, I needed real-time updates for a court case affecting a house I was purchasing. Instead of constantly checking the case manually, I wrote a Python script to automate this process. The script monitors court case information, party details, case documents, and the case calendar. Whenever it detects an update, it sends an email notification.
How It Works
The script downloads the latest court case information and saves it to the ./data/ directory in the following CSV formats:
{case_number}_case_information.csv
{case_number}_party_information.csv
{case_number}_case_documents.csv
{case_number}_case_calendar.csv
If there are new updates, it emails the specific rows with the changes.

Create a New Project (if you don’t already have one):
Click on the project dropdown at the top and select “New Project.”
Enter a name for your project and click “Create.”
Enable the Gmail API:
In the Google Cloud Console, go to the “APIs & Services” dashboard.
Click on “Enable APIs and Services.”
Search for “Gmail API” and click on it.
Click “Enable” to enable the Gmail API for your project.
Create Credentials:
Go to the “Credentials” tab on the left sidebar.
Click on “Create Credentials” and select “OAuth 2.0 Client ID.”
You may be prompted to configure the OAuth consent screen. If so, follow the instructions to set up the consent screen (you can fill in minimal information for internal use).
Choose “Desktop app” for the application type and give it a name.
Click “Create.”
Download the JSON File:
After creating the credentials, you will see a section with your newly created OAuth 2.0 Client ID.
Click the “Download” button to download the JSON file containing your client secrets.
Rename this file to credentials.json and place it in the same directory as your script or specify the correct path in your script.

The Financial Crimes Enforcement Network (FinCEN) now requires most businesses to report their beneficial owners, a mandate stemming from the U.S. Corporate Transparency Act. The penalties for non-compliance are exceptionally harsh. Anyone willfully violating the reporting requirements could face penalties of up to $500 for each day of continued violation, with criminal penalties including up to two years of imprisonment and fines up to $10,000. All the FAQs for BOIR reporting can be found here.
Fortunately, if you only have a few companies, filling out this form should take no longer than 15 minutes. You can access the online filing system here. However, if you have hundreds of LLCs, this process can quickly become overwhelming, potentially taking days to complete multiple forms. To address this, I’ve developed a code to automate the process. If all your companies have the same beneficial owners, this script will streamline the reporting process. However, you will still need to verify your humanity and the information filled out when you reach the CAPTCHA at the end.

Supporting CSV
You’ll need to create a subdirectory wherever you run this program labeled ./data in this folder you can put the JPEG’s of your ID’s which must be uploaded as well as a CSV file with all of your different company names (EIN or SSN depending on how they’re setup) and a column labeled ‘complete’. The script will go through every single company automating your information but just changing these fields for each organization you own. Here is a sample of the CSV file.

Supporting CSV
This code requires a ./data/boir_data.csv file which contains the following column which correspond to each section on the BOIR form.
In the realm of intraday trading, managing and minimizing trading costs is not just a practice; it’s a necessity. A strategy that seems profitable on paper can quickly become a losing proposition when real-world costs, particularly the spread between the bid and ask prices, are factored in. Today, I’d like to share a comprehensive analysis tool I developed to focus on this.
Output
This is the HTML output plot generated by the program. Below you’ll see some data followed by some important metrics. Note that the title has the spread standard deviation in dollars and percent. As well the actual values are shown in the plots below with their distribution and boxplots.
The Importance of Spread Analysis
Bid Price
The “bid” is the highest price a buyer is willing to pay for a stock. It essentially represents the demand side of the market for a particular stock. When you’re selling a stock, the bid price is the most you can hope to get at that moment. It’s a real-time reflection of what buyers believe the stock is worth, based on their analysis, market conditions, and other factors. The bid price is constantly changing as buyers adjust their willingness to pay in response to market dynamics.
Ask Price
Conversely, the “ask” price is the lowest price at which a seller is willing to sell their stock. It represents the supply side of the equation. When you’re looking to buy a stock, the ask price is the lowest you can expect to pay at that moment. Like the bid price, the ask is always in flux, influenced by sellers’ perceptions of the stock’s value, market trends, and various economic indicators.
The Bid-Ask Spread
The difference between the bid and ask price is known as the “spread.” The spread can be a critical indicator of a stock’s liquidity and market volatility. A narrow spread typically indicates a highly liquid market with a high volume of transactions and minimal difference between what buyers are willing to pay and what sellers are asking. Conversely, a wider spread suggests lower liquidity, potentially making it more challenging to execute large trades without affecting the market price.
Now that we’ve explored the bid-ask spread let’s establish why spread analysis is crucial. The spread directly impacts your trading costs. For high-frequency traders, even small variances in this spread can significantly affect overall profitability. My tool is designed to subscribe to Alpaca’s API, fetching real-time quotes and prices alongside their volume. This setup allows us to compute the spread both as a dollar value and as a percentage of the asset’s value, offering a clear view of the trading costs involved.
The Tool’s Anatomy
The tool comprises two Python files: alpaca_plots.py and alpaca_functions.py. The former is primarily responsible for the data visualization aspect, while the latter deals with data fetching, processing, and statistics calculation.
Key Functions and Their Roles
Data Subscription and Handling: At the core, my tool subscribes to quote and trade updates via Alpaca’s API, focusing on a list of specified symbols. This is crucial for accessing real-time data, essential for accurate spread analysis.
Spread Calculation: Once data is fetched, the tool calculates the spread in both dollar value and percentage. This is done by subtracting the bid price from the ask price for each quote, providing an immediate measure of the trading cost for that specific asset.
Statistical Analysis: Beyond mere calculation, the tool also analyzes the distribution of spread values, including their standard deviation. This statistical approach allows traders to understand not just the average costs, but also the variability and risk associated with the spread.
Data Visualization: A key feature is its ability to generate insightful visualizations, including boxplots. These plots offer a visual representation of the spread distribution, highlighting the median, quartiles, and any outliers. This visual context is invaluable for traders looking to assess the cost implications of their strategies quickly.
Practical Application and Insights
By analyzing the spread in both absolute and relative terms, traders can make informed decisions about which assets to trade and when. For example, a high spread as a percentage of the asset’s value might deter trading in certain assets during specific times, guiding traders towards more cost-effective opportunities.
In Summary
This tool is more than just a technical exercise; it’s a practical solution to a problem many traders face daily. By offering a detailed analysis of Alpaca spreads, it empowers traders to make data-driven decisions, ultimately enhancing the profitability of their trading strategies. Whether you’re a seasoned trader or just starting, understanding and applying such tools can significantly impact your trading success.

Today, I dove into housing data and decided to filter houses based on price to determine how it impacted sales numbers. The graph below illustrates Listings Under Contract up until March.
The overall findings are not particularly surprising. Last month, 8,401 listings were under contract, which represents a significant decrease compared to the last 10 years. Given the current interest rates, this is not unexpected. However, in the chart below when we focus on houses priced over $1M, an intriguing trend emerges. In March, 1,020 houses sold for more than $1M, its highest level ever. This indicates that affluent buyers are still actively purchasing expensive properties, at their fastest pace ever.
Inventory
To gain a more comprehensive understanding of the market, let’s look at the days of inventory. For houses priced over $1M, the current days of inventory stand at 170 days, a notable increase from the low of 43 days. However, this figure is roughly equivalent to the levels observed in October 2020. While the trend is undoubtedly increasing, it’s crucial to consider the broader context.
When analyzing the days of inventory across all price points, we find that there are approximately 81 days of inventory, chart below. To find comparable levels, we must go back to December 2016. This suggests that the overall housing market is experiencing a severe slowdown, with inventory levels reaching heights not seen in almost a decade.
The divergence between the luxury segment and the overall market raises important questions about the factors driving demand and supply in different price ranges. While affluent buyers seem to be less affected by the current economic conditions, the broader market appears to be more sensitive to interest rates and other macroeconomic factors. So if you’re in the market for $1M+ house you might not see any good deals anytime soon. Or perhaps the demand for $1M+ houses is just latent to the overall market.
