Summary: This article introduces the "detachment" rule from a former chief Asia FX strategist at an investment bank. It details the specific methods professionals use to filter noise, maintain independent thinking, and manage risk with strict stop-loss discipline.




The trading floor was buzzing. It was a major US jobs report release, and screens were flashing with conflicting numbers. The junior traders were scrambling, trying to catch the first move, some buying, some selling, most just reacting.

In the corner, a man sat still. He didn't touch his keyboard. He didn't even seem to be watching the screen with any urgency. He was Ken Cheung, a former Chief Asia FX Strategist at a major investment bank. He was doing exactly what he had learned to do over years of managing multi-million dollar institutional portfolios: he was filtering the noise.

"Information flows so fast now," Ken would later explain. "Institutions and retail traders receive almost the same news at the same time. The real edge is how you filter the noise and think independently."

The Core Mindset: Detachment from the Herd



Ken's trading philosophy, honed in the pressure cooker of a global investment bank, centers on a single, powerful concept: detachment.

This doesn't mean ignoring the world. It means actively separating information from noise. In his view, most retail traders make the mistake of treating every piece of news as actionable. The noise — the initial spike in volatility, the first round of commentary, the social media panic — destroys their judgment.

"The traders at a bank, they look at the same charts and news as you," Ken says. "The difference is they have a process to process that information."

This process is what I call the "Detachment" rule. It's a three-step checklist that turns a reactive trader into a proactive one.

The "Detachment" Rule: A Three-Step Checklist



Step 1: The News Filter



Ken's rule starts with a simple but brutal self-assessment: "Is this news actually relevant to the medium-term trend, or is it just noise?"

  • Actionable News: Economic data that fundamentally changes interest rate expectations (e.g., a major shift in CPI or unemployment figures that alters central bank policy projections).

  • Noise: The initial "headline" reaction, comments from non-influential officials, or the first few minutes of volatile price action after a data release.


    • The Rule: Do not execute a trade based on the first 15 minutes of price action following a major data release. Let the market digest the information. As Ken notes, the professional approach is to "look at macro themes and whether they will continue or whether the market is overheating." You can't judge that in the first few seconds of chaos.

    Step 2: The Independent Thinking Filter



    Once the news has been filtered, the second step is about thinking independently. Ken emphasizes that "the advantage of institutional traders is not just getting information first, but also exchanging views with peers." This peer exchange, however, is a double-edged sword. It can lead to groupthink.

  • The Rule: If a majority of traders are leaning one way, your job is to challenge that consensus. This is a fundamental part of a professional's independent thinking. You must ask: "Is this consensus already priced in? What is the risk of the consensus being wrong?"


    • Step 3: The Risk Management Filter



    This is where the "detachment" rule becomes specific and mechanical. Investment banks use strict risk limits to control their traders and prevent catastrophic losses. Ken recommends retail traders adopt the same discipline.

    He explains that banks force traders to do two things:
  • <strong>Set a stop-loss on every trade.</strong>

  • <strong>Adhere to a maximum position size.</strong>


    • Ken takes this a step further. He notes that one of the biggest mistakes retail traders make is moving their stop-loss after entering a trade, or worse, averaging down on a losing position, which increases risk. "They might set a stop-loss, but then think it's inappropriate and change it," he says. "This leads to bigger losses."

    The Specific, Executable Rules



    Based on Ken's principles and the practices of institutional traders, here are the concrete rules you can implement:

    1. The "Trading Diary" and Risk Cap



  • Rule: Every trade must be logged with a clear rationale. More importantly, the total risk across all open positions must not exceed a set percentage of your account.

  • Institutional Practice: Banks impose a cap on the maximum position a trader can take. For retail traders, a sensible cap is 5% of total account equity for all open positions combined.


    • 2. The 15-Minute Pause (The Noise Filter)



  • Rule: After any major economic data release (NFP, CPI, FOMC, etc.), you must wait for the first 15-minute candle to close before considering any new position.

  • Why this works: The "market noise" creates initial false moves. The first 15-minute candle often shows the true direction. If the candle closes with a long wick, it signals rejection of that level — a potential counter-trend opportunity.


    • 3. The "Golden Pair" (Technical + Macro Analysis)



    Ken recommends using a combination of technical and macro analysis. This is called the "golden pair" in professional circles.

  • Technical: Use charts to identify support and resistance levels, and find your entry and exit points.

  • Macro: Use the macro news to judge the validity of the technical signal.


    • An Original Viewpoint: The "Detachment" Rule in Today's Market



    In 2026, the "Detachment" rule is more relevant than ever, but it also faces a unique challenge: the speed of information. As Ken points out, AI and instant news have leveled the playing field on information access. "Institutional traders no longer have a unique advantage in information processing," he notes. "Retail traders don't have an information disadvantage."

    This is the double-edged sword. The noise is louder than ever. Social media and news alerts can make you feel like you're missing out if you don't act immediately.

    My Experience:
    I have adapted the "Detachment" rule to my own trading with a specific "No-Action" zone. In my own trading during the volatile swings of 2025 and 2026, I've found that the 15-minute pause rule consistently saves me from chasing false breakouts. The best trades I've taken were the ones where I waited for the initial "noise" to settle, saw the price reject a key level, and then entered.

    Conclusion



    Ken Cheung's approach to the market is a powerful reminder: the goal is not to be the first to act, but to act correctly. By filtering the noise, thinking independently, and managing risk with the discipline of a professional, you can remove the chaos from trading and focus on what matters: the trend.
