The Algorithmic Advantage

Ex-prop trader on why solo trading is a different game, and how to win with real edges & portfolios of noisy strategiesKris Longmore of Robot Wealth went from aimless data mining to an equity partnership at a Sydney prop firm, all because a professional trader asked him one question: "What's your edge?" In this episode, he explains why solo trading is a completely different game from professional trading, and why success comes down to picking games you can actually win. We cover why keeping your day job isn't a failure, the two fundamental ways traders get paid, and how to build a portfolio in layers: robust risk premia at the base, with flow and seasonality trades stacked on top.Kris also shares specific strategy ideas, including the SPY/TLT month-end rebalance, the bond end-of-month effect, equity stat arb and long volatility into earnings. He explains why breadth beats polish when your portfolio is small, why you should automate only what you need to, and why machine learning is a tool, not an edge. Members can catch the bonus segment, where Kris breaks down his research process: the three questions he asks of every idea, why he doesn't hold out data, and why a slam-dunk result should make you nervous.My Write Up: https://algoadvantage.substack.com/p/the-part-time-trader-part-1Research: https://algoadvantage.substack.comCourses & Community: https://algoadvantage.io/collectiveMusic:Intro & Outro created by me on Suno - Algo Analogue I call it.Pre-Intro - Your Destiny from HookSounds - No subscription licensing.Tags: #SystematicTrading #QuantTrading #SoloTraderContents:0:00 What’s Your Trading Edge?8:30 The Question That Changed Everything17:58 How Solo Traders Should Get Started27:00 Building a Diversified Trading Portfolio36:03 Exploiting Predictable Rebalancing Flows45:17 How to Find Real Trading Edges52:52 The Systematic Trader’s Tech Stack59:12 R vs Python for Quant Trading1:04:16 Why Machine Learning Isn’t an Edge1:07:10 The Four Hats of a Solo Trader

Toby Crabel — founder of Crabel Capital Management (~$5B AUM) and author of the legendary *Day Trading with Short Term Price Patterns and Intraday Breakouts* (1990), the book that gave the world the opening range breakout and NR4/NR7 patterns — joins the show for a rare, wide-ranging conversation. Toby traces his path from a pro tennis career to the Chicago trading floors, his formative stints with Victor Niederhoffer and his early connections to Monroe Trout and Paul Tudor Jones, and how zero-commission floor trading shaped his short-term edge from day one. He unpacks why the "clean open" that powered ORB for decades has eroded under 24-hour markets and institutional flow, why studying historical price shocks (1987, COVID) is non-negotiable for systematic survival, and why PhDs and machine learning are no substitute for a causal, market-structure-driven research process. For the solo systematic trader, Toby's advice is refreshingly practical: start with one market, build strict rules around a single idea, and know exactly when your edge has died. A must-watch for anyone serious about the history, robustness, and future of short-term systematic trading.Research: https://algoadvantage.substack.comCourses & Community: https://algoadvantage.ioMusic:Intro & Outro created by me on Suno - Algo Analogue I call it.Pre-Intro - Your Destiny from HookSounds - No subscription licensing.Contents:0:00 AI, Quant Research and Market Regimes5:50 Toby Crabel’s Systematic Trading Origins13:00 How the Opening Range Breakout Was Built18:36 Lessons from Legendary Traders25:04 Why Traders Must Study Market History30:22 How 24-Hour Markets Changed Trading38:02 How Systematic Trading Has Evolved45:17 Crabel’s Multi-Market Strategy Portfolio53:32 Trading as a Business59:58 Price, Volume and Wyckoff Principles1:06:31 Trading Short-Term Strategies at Scale1:14:00 Capacity, Execution and Market Impact1:22:00 Systematic Risk and Portfolio Management1:30:00 Advice for the newer trader1:38:00 The Future of Systematic Trading

Trading your own account was never going to replace a salary — the compounding you need gets wiped out by the withdrawals you need to live on. The more commercial option is to trade investor capital, but the options are limited.In this video we get a look inside a trader's journey with Darwinex, quickly establishing a track record and attracting external capital.In the Substack article I break down why prop firm evaluations are built for the firm to win, not you: daily loss limits, trailing drawdown, and consistency rules that quietly punish traders with genuine edge. I talk about why fixed stop-losses backfire to explain exactly why trailing drawdown is the worst offender, and why the industry's real ~10% pass rate says far more about the rules than about trader skill. Then I cover the alternative most traders never consider: platforms like Darwinex, where there's no evaluation to survive, just a certified track record and capital that's actually incentivised to see you succeed.Check it out: https://algoadvantage.substack.com/publish/post/207723117I've just released an incredible 'Trading Breakthroughs with AI course' for members of the Collective.

Big discount on Martyn's tool for subscribers: https://www.algoadvantage.io/toolbox/Watch Part 1 first! https://youtu.be/Kxvp00VbLx0My detailed write up on Walk Forward Correlation Analysis: https://www.algoadvantage.io/podcast/053-martyn-tinsley-2/Martyn introduces Walk Forward Correlation (WFC) as a diagnostic for two problems that sit at the heart of systematic trading: over-fitting and structural edge. Traditional walk-forward analysis typically optimizes a strategy on an in-sample window, picks the “best” parameter set, then tests that one choice out-of-sample. Used the wrong way, there’s a potential flaw here: one parameter set can look good out-of-sample purely by accident. That tells you very little about whether the underlying model is genuinely robust.Tinsley’s move is simple, but useful. Instead of judging one selected point, he looks at all parameter combinations in the optimisation grid and asks a harder question: does strong in-sample performance tend to map to strong out-of-sample performance across the whole space? If yes, you may have something real. If no, you’re probably flattering noise.Contents:0:00 Walk Forward Correlation Explained 4:22 Best Metrics for Strategy Selection9:27 Building a Combined Performance Metric13:05 Objective Functions and Walk Forward Tests17:30 In-Sample vs Out-of-Sample Validation22:28 Pre-Live Optimization for Live Trading25:14 Why Traditional Walk Forward Falls Short28:59 Walk Forward Correlation Method32:28 Measuring Predictive Power in Trading39:25 Reading Correlation Chart Scenarios41:48 Trade Counts and Statistical Significance45:52 Go/No-Go Gates for Robust Strategies51:03 Optimize Strategy Software Overview56:43 Final Thoughts for Systematic Traders
