Very true. Nice explanation of this concept!
THE SHORTEST TIMEFRAMES HAVE THE MOST EDGE! This is a view Iโ€™ve mentioned before in interviews, but Iโ€™ve never taken the time to fully expand on. In general, you want to be an expected value maximalist (within risk constraints). And the shortest human timeframes offer that. Yes, I mostly do bigger picture trades now but thatโ€™s due to scalability and quality of life, not bc they offer the most edge. The paradox of markets is this: -The shortest timeframes often have the biggest dislocations (most โ€œedge per minuteโ€) -The longest timeframes often have the biggest tailwind (asset prices tend to rise over time) -The middle is where many traders get chopped up This principle is the reason why there were traders at Trillium that could be positive hundreds of days in a row. Youโ€™ll never see that with a swing trader or value investor. 1. Why short timeframes can have so much edge At very short horizons, markets can be temporarily inefficient because of: -forced behavior (stops, liquidations, margin pressure) -delayed human interpretation of information -mechanical flows around opens/closes -short-lived supply/demand vacuums Those create moments where price can be โ€œwrongโ€ for seconds/minutes relative to where itโ€™s about to reprice. In fact, at the extreme short end of human discretionary trading like the two following examples, you can find opportunities that approach 100% win rate with a profit factor of 10 . Of course there is a trade-off which Iโ€™ll get into. 2. Order flow imbalances One of the biggest short-term edges is understanding order flow imbalance. Yes, these happen far less of the now than they used to as discussed in my interview yesterday with Serge. But they still exist particularly during times of market extremes. -aggressive buyers/sellers temporarily overwhelm passive liquidity -one-sided flow causes price to overshoot or stall -liquidity can disappear at key moments, then refill at new levels Youโ€™ll see this around: -opening auctions -panic flushes / squeezes -large fund rebalancing windows -crowded positioning unwinds This is where the tape can get dislocated from โ€œfairโ€ value in the short run and where active traders can extract edge. It is also why some of those hyperscalpers like @EdBarry4 are positive so many days in a row. 3. Breaking news is where discretionary human traders still have the edge over algos in interpreting novel headlines. Thereโ€™s usually a sequence: -headline reaction -second-order interpretation -positioning unwind/chase -stabilization If youโ€™re prepared and fast, these windows can be highly asymmetric. In fact, breaking news can offer some of the best opportunities in existence, especially when applied to liquid instruments (think April 2025 tariff headlines!). In fact, Iโ€™d argue tariff headlines due to their massive impact on global markets are some of the best expected value opportunities Iโ€™ve ever seen. 4. But thereโ€™s a tradeoff: liquidity scalability The shorter the timeframe, the more your edge depends on: -execution speed -order optimization -fee minimization -slippage minimization So yes, edge can be highest in short windows but liquidity becomes the constraint. Many short-duration edges donโ€™t scale without degrading returns. That is why many traders post eye-watering returns in small caps but then you constantly see them doing their dumb small account challenges. Itโ€™s because their strategies donโ€™t scale! 5. Beware the middle ground. Take this thought experiment. Letโ€™s say $AAPL flash crashes 90%. With near-certainty, Apple will bounce within minutes close back to the unaffected price. What happens overnight is more of a toss-up. What does the market do? Does news come out? Yet over the course of 5-10 years, itโ€™s likely the $AAPL goes up. In that middle ground, you take on variance from overnight risk, headline risk, and market risk. But donโ€™t benefit much from the fact that over years, markets go up. Itโ€™s much more of a coin flip whether we go up or down any given day. If I had to guess, the most edge is in tenths of seconds and seconds for humans. The least edge is in the window of weeks. Why not compete at even faster timeframes? Bc then you fight with HFT, commission structures, co-location, and more. 6. So how to apply this? First, this is useful for the sniff test. Understanding that there is a trade-off between edge and liquidity is critical! There is a reason why you see small cap traders that can scale a small account over 1,000% in a year (think early days of @theshortbear). There is also a reason why Warren Buffett has approached market returns. Itโ€™s that trade-off between edge and scale. Similar to the general trade-off between win-rate and profit factor, itโ€™s a safe assumption that these often tend to move inverse to each other. Itโ€™s the reason why that if I managed $1B my returns would probably get quartered and if I managed $10B my returns would approach market returns or worse. This framework is also useful for finding the most edge and understanding your strategies. If youโ€™re moving to a higher timeframe, you generally SHOULD expect more variance. That comes with the benefit of scalability. Similarly, if you want to study micro-inefficiencies, particularly in less efficient markets like crypto, you can find some insane edges there.

The "All on my own" trader is a myth that limits your P&L. If you want to be your best, stop hoarding your "secret sauce" and start building a team. ๐Ÿงต Trading is often sold as a solo journey, but the fastest way to find a new edge is through the eyes of someone who thinks differently from you. What youโ€™ll learn from this philosophy: The Trust System: Collaboration isn't "willy-nilly"โ€”itโ€™s a systematic process of building trust with peers. The Giverโ€™s Advantage: Being a "default giver" opens doors to strategies and ideas you literally couldn't conceive of on your own. The Achilles Heel Fix: When you stop hoarding tools and start sharing, you find partners who fill your blind spots. The Insight: "The more you share as a trader, the more you're going to get back. Most people are takers; they are only thinking about themselves. You should be thinking about how you can improve someone else's life and make their trading better. When you start thinking that way, you develop collaborations with people who think in completely different ways than you do. They will share ideas with you that you would literally never think of on your own."- @DaveMabe (1:08:00 ๐Ÿ‘‡) #TradingPsychology #TradingMindset #Collaboration Your Trading Strategy Will Fail Until You Understand This ONE Process youtu.be/pPIPvyticq4?si=B_59โ€ฆ via @YouTube @GarrettDrinon @BeldenTim

In the latest episode of the @smbcapital Trading Floor Podcast, we sat down with @davemabe (founder of MabeKit) as he broke down his path to high-output systematic trading. We learned that optimization is the true edge, not the initial signal. Mabe argues that "good traders are just skipping the bad trades," and systematic tools allow you to do this with mathematical precision. Dave shows us how building a robust "column library" of indicators, traders can move away from "guess-and-check" loops and toward a repeatable process of strategy discovery and refinement. This conversation felt just like one of the many times @BeldenTim and I have sat down over coffee with Dave to pick his brain, and thatโ€™s why I enjoyed this episode so much. youtu.be/pPIPvyticq4?si=VPNGโ€ฆ

The first backtest is meant to build a large data set, not your final strategy. Edge comes from refining that data over time. ๐Ÿ‘‰ Watch the full video with @davemabe here: investorsunderground.com/davโ€ฆ

The best way to minimize the time it takes your backtest to run is to set up your process to minimize the number of backtests you need to run at all.

Sorry, but you're not important enough for anyone to be "hunting" for your stop. Here's the right way to come up with a strategy with a stop loss that's optimal. That means you'll be stopped out by a penny routinely. Which is a good thing: lineyourownpockets.com/episoโ€ฆ

The hosts delve into several key takeaways and offer advice for traders: ๐“๐ก๐ž ๐๐จ๐ฐ๐ž๐ซ ๐จ๐Ÿ ๐–๐ซ๐ข๐ญ๐ข๐ง๐  ๐š๐ง๐ ๐’๐ก๐š๐ซ๐ข๐ง๐  [๐ŸŽ๐Ÿ:๐ŸŽ๐Ÿ’]: @DaveMabe recounts how he met me. I reached out after reading Dave's blog, where Dave shared his thoughts on trading. Dave emphasizes that everyone should write about their trading ideas, even if just "shouting into the void," as it can lead to unexpected connections and opportunities. ๐๐ซ๐จ๐ฉ๐ซ๐ข๐ž๐ญ๐š๐ซ๐ฒ ๐“๐ซ๐š๐๐ข๐ง๐  ๐…๐ข๐ซ๐ฆ๐ฌ ๐ฏ๐ฌ. ๐‘๐ž๐ญ๐š๐ข๐ฅ ๐“๐ซ๐š๐๐ข๐ง๐  [๐ŸŽ๐Ÿ”:๐ŸŽ๐Ÿ—]: The hosts discuss the advantages of prop firms like SMB Capital, highlighting that traders there are highly serious and focused, creating a competitive yet collaborative environment. They note that prop firms often get significantly better commission rates. ๐ƒ๐ข๐ฌ๐œ๐ซ๐ž๐ญ๐ข๐จ๐ง๐š๐ซ๐ฒ ๐š๐ง๐ ๐’๐ฒ๐ฌ๐ญ๐ž๐ฆ๐š๐ญ๐ข๐œ ๐“๐ซ๐š๐๐ข๐ง๐  ๐‚๐จ๐ฅ๐ฅ๐š๐›๐จ๐ซ๐š๐ญ๐ข๐จ๐ง [๐ŸŽ๐Ÿ–:๐ŸŽ๐Ÿ–]: SMB Capital is primarily a discretionary trading firm, but the hosts see great potential in integrating systematic trading. They believe that if done correctly, discretionary insights can beautifully feed into systematic strategies. ๐“๐ก๐ž "๐–๐ก๐ฒ" ๐๐ž๐ก๐ข๐ง๐ ๐“๐ซ๐š๐๐ข๐ง๐  ๐’๐ญ๐ซ๐š๐ญ๐ž๐ ๐ข๐ž๐ฌ [๐Ÿ‘๐ŸŽ:๐Ÿ๐Ÿ‘]:ย A crucial point for successful collaboration between discretionary and systematic traders is understanding the "why" behind a strategy. Systematic traders need to translate data-driven insights into a coherent story that resonates with discretionary traders, rather than relying solely on complex models like Monte Carlo simulations. Strategies with a strong underlying psychological or market participant reason are generally more robust and easier to adapt when market conditions change. ๐‚๐จ๐ฅ๐ฅ๐š๐›๐จ๐ซ๐š๐ญ๐ข๐จ๐ง ๐š๐ฌ ๐š ๐…๐จ๐ซ๐œ๐ž ๐Œ๐ฎ๐ฅ๐ญ๐ข๐ฉ๐ฅ๐ข๐ž๐ซ [๐Ÿ‘๐Ÿ‘:๐ŸŽ๐Ÿ]:ย Using a cycling analogy, the hosts explain that just as a group of cyclists can go much faster together than individually, traders can achieve greater success through collaboration. This applies even when skill levels vary, as sharing ideas and working together amplifies collective performance. ๐๐ž๐œ๐จ๐ฆ๐ž ๐š ๐†๐ข๐ฏ๐ž๐ซ [๐Ÿ‘๐Ÿ–:๐Ÿ“๐Ÿ‘]: To foster collaboration, traders should aim to be "givers" rather than "takers." This means offering value, such as systematizing a discretionary trader's ideas or sharing thought processes, to build trust and attract like-minded individuals. They recommend the books ๐บ๐‘–๐‘ฃ๐‘’ ๐‘Ž๐‘›๐‘‘ ๐‘‡๐‘Ž๐‘˜๐‘’ by Adam Grant and ๐‘‡โ„Ž๐‘’ ๐บ๐‘œ-๐บ๐‘–๐‘ฃ๐‘’๐‘Ÿ. ๐ƒ๐จ๐ง'๐ญ ๐“๐ซ๐š๐๐ž ๐€๐ฅ๐จ๐ง๐ž [๐Ÿ’๐ŸŽ:๐Ÿ’๐ŸŽ]:ย The hosts note that I suggest a "surgeon general warning" for traders: "Don't trade alone." The hosts agree that despite trading often being a solitary activity, pushing for collaboration, even by sharing content online, is the best way forward. The hosts note that SMB traders trade shared accounts to further encourage this collaborative environment. Follow Up On Quant/Discretionary Collaboration youtu.be/_j4PN31DJOE?si=tuv0โ€ฆ via @YouTube
