Video Summary

I Re-Created A Quant Trading Strategy With Claude Code (Insanely Cool)

Lewis Jackson

Main takeaways
01

Markets are divided into three states (bull, sideways, bear) using 20‑day trailing returns: ≥+5% bull, ≤−5% bear, else sideways.

02

Label every day in an asset’s history, count state transitions, and build a 3×3 transition matrix of next‑day probabilities.

03

The Markov property: tomorrow depends only on today’s state; persistence ('stickiness') drives position sizing.

04

Square (or exponentiate) the transition matrix for multi‑day forecasts; long horizons approach the stationary distribution.

05

Generate a trading signal by subtracting bear probability from bull probability; use walk‑forward backtesting to avoid data leakage.

Key moments
Questions answered

How are bull, bear, and sideways states defined?

States use the trailing 20‑day return: bull if ≥ +5%, bear if ≤ −5%, and sideways for returns between those thresholds.

What is the purpose of the 3×3 transition matrix?

It records counts of day‑to‑day state transitions and converts them to probabilities for predicting tomorrow’s state given today’s.

How do you forecast multiple days ahead with this method?

Compute powers of the transition matrix (e.g., square for two days) to get multi‑day transition probabilities; longer horizons approach the stationary distribution.

Why use walk‑forward backtesting instead of standard backtests?

Walk‑forward retrains and recalculates the model stepwise to prevent using future data (data leakage) and gives a more realistic performance estimate.

What benefit does a hidden Markov model (HMM) add?

HMM removes subjective labeling by letting the model infer regimes from price dynamics, classifying states via observed patterns rather than fixed thresholds.

The Difference Between Retail Traders and Quants 00:11

"Average people who are trying day trading do it completely differently than hedge funds."

  • Retail traders often rely on emotions and personal instincts when making trading decisions, while quant traders utilize advanced methodologies that focus on numerical analysis.

  • Quants bypass traditional methods such as trend lines and indicators, instead employing sophisticated models that can yield more consistent results over time.

  • The video introduces the concept that quant trading operates on analytics rather than feelings—traders make decisions based on quantifiable data.

The Hedge Fund Method Overview 00:58

"I'm going to share exactly what the hedge fund method is and convert it into a format understood by AI."

  • The hedge fund method encompasses a systematic approach to trading, involving specific formulas and strategies developed by successful professionals in the finance industry.

  • The host plans to distill complex quant methods into actionable steps that viewers can implement, including prompts for AI tools like Claude.

  • By the end of the video, viewers are equipped with techniques that can transform their trading strategies to mimic those employed by hedge fund quant specialists.

Understanding Market States 03:00

"Every hedge fund and quant will operate with states. There are only three states: bull, sideways, and bear."

  • The three market states are categorized as bull (when returns over the last 20 days are 5% or more), bear (when they are -5% or worse), and sideways (anywhere in between).

  • Accurate analysis of current market conditions relies on labeling historical data, allowing quants to understand the state of an asset over time, such as Bitcoin.

The Markov Property in Trading 04:38

"The market only moves to the next place as a result of where it is today."

  • The Markov property emphasizes that past performance is not necessarily indicative of future movements; only current conditions influence the next market state.

  • Traders should focus on today's market rather than rely solely on historical data to predict future migrations, leading to more informed decision-making.

The Hedge Fund Matrix and Transition Counting 06:03

"With all that data from the history of Bitcoin, there are moments in time where the state shifts."

  • Quants track transitions between different states (e.g., from bull to bear) and quantify how often these changes occur, creating a comprehensive record of market behavior over time.

  • The information from these transitions is turned into probabilities, forming a 3x3 grid that assists in forecasting future market movements based on existing states.

The Concept of Persistence and Stickiness 08:32

"Every state has a stickiness score essentially."

  • Each market state (bull, bare, sideways) exhibits a level of persistence, meaning that if a market is in a bull state today, it is more likely to remain in that state tomorrow.

  • Understanding the "stickiness" of market conditions allows traders to make better predictions about future movements, as persistent trends can influence short-term decisions.

The Live Matrix Scoreboard and Its Application 08:58

"This is what the quants and the hedge funds use to determine where to place their bets today."

  • The video discusses a live matrix scoreboard that estimates the probability of market outcomes for the following day, a method commonly employed by quantitative analysts and hedge funds.

  • An example given is a "stickiness score" for a bull market, defined as having an 80% chance of persisting into the next day.

  • This information allows traders to hedge their bets based on statistical probabilities rather than mere speculation.

Installing the Pine Script Indicator 09:30

"I've created a Pine Script for an indicator that shows the matrix on a chart that you can use right now."

  • The host mentions the creation of a Pine Script that visualizes the matrix on a chart in Trading View, making it accessible for viewers to use in trading various assets.

  • The tutorial segment will guide users on how to install this script to visualize a 3x3 matrix indicative of market states.

Understanding Market States and Mathematical Models 09:54

"We’ve talked about what a state is and decided today’s state based on the last 20 days of movement."

  • The host summarizes key components that were introduced earlier, including defining market states, identifying the current state based on historical data, and explaining the Markov property.

  • Detailed explanations cover the transition matrix that quant funds utilize, showcasing how probability scores predict future market states.

Forecasting Beyond One Day: Squaring the Matrix 10:40

"There actually is a calculation for that, and I'm going to show you. It’s called squaring the matrix."

  • The video highlights how traders can forecast beyond a single day by squaring the matrix, allowing for predictions of multiple days into the future by multiplying the matrix by itself for each additional day.

  • For example, to predict two days ahead, one would square the matrix, resulting in a calculated probability of remaining in a bull state that decreases over time.

Practical Examples of Probability Calculations 11:22

"By doing that calculation for all the different combinations, you end up with a way to show what the chances are of an asset being in a specific state."

  • The host provides a step-by-step walkthrough of how to calculate the probabilities for extended forecasts, emphasizing the decreasing confidence in predictions as the timeframe increases.

  • The percentages of potential outcomes are relayed visually in a matrix format, distinct from traditional trend line approaches.

Transition to Signal Generation for Trades 13:32

"What do I do with that information? Well, despite all of the calculations, the signal generation is incredibly easy."

  • Here, the host addresses the application of the probability calculations into actionable trading signals.

  • By subtracting the probability of a bear market from that of a bull market, traders can derive a differential that drives the amount of capital allocated to each trade.

Walk Forward Backtesting Explanation 16:10

"The issue with backtesting is that you take the strategy with all the information it has learned from the data, and apply it to the future."

  • A critical insight shared involves the distinction between traditional backtesting methods and the walk forward backtesting approach.

  • The host notes that conventional backtesting often incorporates future data into past strategies, leading to misleading results. This highlights the importance of rigorous testing methods that maintain the integrity of historical data in trading algorithms.

Data Preparation and AI Integration 17:24

"Every single day has to be entirely recalculated, so the whole matrix has to be entirely redone."

  • The process involves gathering current data and learning from historical data from at least 2020 and 2021. It addresses challenges related to traditional backtesting methods through walk-forward backtesting, which helps avoid the pitfalls of using outdated strategies based on past performance alone.

  • This recalibration of the data is computationally intensive, yet essential to ensure that the trading strategy remains relevant and effective for current market conditions.

Eliminating Subjectivity in Market States 18:02

"Step number 10 closes all of that out and solves that problem."

  • The video discusses the need to define market states—bull, bear, and sideways markets—and highlights the subjectivity that comes with human interpretations of these states.

  • The introduction of the hidden Markov model addresses this flaw by removing subjective labels and instead analyzing price transitions through pattern recognition.

Understanding the Hidden Markov Model 18:56

"It's looking at details like the continuation of the price going up or the price going down."

  • The hidden Markov model is akin to a babysitter observing children without pre-conceived notions, allowing the model to identify market behaviors based solely on data rather than human-imposed labels.

  • Over time, it classifies market conditions into states—bull, bear, and sideways—without relying on previous labels, offering a more accurate representation of the market dynamics.

Application of the Strategy to Trading 20:50

"We need a real way to apply this into our own trading strategies."

  • The video outlines a practical approach for viewers to implement the discussed strategies using AI tools. It introduces a Claude Code skill that can be integrated into any trading strategy, allowing for adaptations based on the hidden Markov model methodology.

  • Additional resources such as a Pine Script for visualizing the probabilities of market conditions in Trading View are also provided, aiming to simplify the implementation for users regardless of their AI or trading experience.

Installation and Setup Instructions 22:14

"Go to the first line in the description of the video and you'll be brought to a GitHub page."

  • Viewers are guided on how to access the GitHub page containing all relevant code and scripts related to the Markov hedge fund method.

  • The installation involves simply copying the provided code into Claude Code or any compatible LLM, followed by a straightforward onboarding process that makes it ready for use. After setup, users can apply the methods to any asset, demonstrating the versatility of the proposed strategy.

"The bull percentage for tomorrow shows a 29% chance of a bull run."

  • The video discusses statistical probabilities regarding market trends for the upcoming trading day. It indicates a 29% chance of experiencing a bull run, alongside a 42% chance of entering a bear market and a 29% likelihood of the market going sideways.

  • The conversation highlights that the current high likelihood of a bear market is attributed to recent bearish behavior in the market, indicating a persistent state that traders should be aware of.

Practical Application of Quant Strategies 26:31

"You can apply this to any asset, including stocks like Tesla."

  • The speaker demonstrates the versatility of the quantitative strategies being discussed, providing examples with specific cryptocurrencies like XRP and even traditional stocks like Tesla.

  • This illustrates that such strategies can be applicable across various assets, not just within cryptocurrency, broadening the scope for potential investors.
