In the trading world, most gurus preach the gospel of "trend is your friend." They urge you to catch the big moves, ride the momentum, and let profits run. But what if your trading style doesn't fit that mold? What if you are more comfortable in chaos, in the back-and-forth chop that makes most traders tear their hair out?
There is a surprisingly effective philosophy for this: the Grid Trading Mindset. It is a strategy often dismissed as "beginner suicide" by risk managers, yet when executed with extreme discipline and specific rules, it can yield staggering results. To understand this, we need to look at a relatively obscure figure in the online trading community: Nayuta Yokoyama, a Japanese trader who flew under the radar until he posted a stunning performance in a prop firm competition.
The "Non-Mainstream" Trader
In August 2025, Nayuta Yokoyama participated in a DooPrime trading competition. In just 12 days, he achieved a return of 1,376.94% , claiming second place in his group . How did he do it? Not by catching a massive trend, but by grinding out tiny profits in range-bound markets using a meticulously crafted grid trading system .
What makes Yokoyama's story relevant is not the flashy return but his background: he is a self-taught trader who had been watching the foreign exchange market for over 18 years . His journey is a testament to focusing on a single, highly specific strategy and polishing it until it shines.
The Grid Trading Mindset: Embracing the Range
The grid trading mindset starts with a simple observation: not all markets trend. In fact, most of the time, currency pairs move sideways. The majority of traders lose money trying to predict the breakout. Yokoyama's philosophy is to accept the uncertainty and profit from the noise.
His approach is to trade "mean reversion" within a range. When the price moves up, he sells. When it moves down, he buys. This is the opposite of the trend-following "let profits run" mantra. The goal is to catch small "ticks" of profit.
However, the grid strategy's most significant weakness is risk. If a trader mechanically adds to losing positions, they will face a catastrophic loss if a strong trend suddenly appears. Yokoyama's secret is not just the grid itself but the rigorous rules he built around it .
Actionable Rules: The "Sniper's Grid"
Here are the specific, actionable rules derived from Yokoyama's approach and the discipline of successful grid traders. If you want to apply this "counter-trend" mindset, you need these boundaries.
1. Choose the Right Instrument (The "Correlation Filter")
You cannot trade a grid on a volatile pair like GBP/JPY. The risk of a runaway trend is too high. Yokoyama specifically trades only AUD/NZD and EUR/GBP. Why? Because the economies of Australia/New Zealand and Europe/UK are highly correlated . This structural relationship creates strong range-bound behavior; they rarely show prolonged divergence. This is a crucial filter that reduces the risk of a sudden trend wiping out the grid.
2. The ATR-Based Grid Spacing (Not Fixed Pips)
The most common mistake in grid trading is using a fixed pip distance (e.g., adding every 10 pips). Yokoyama bases his grid spacing on the Average True Range (ATR) . This means the space between grid levels expands and contracts with market volatility. In volatile markets, the spacing is wider, preventing premature entries. In quiet markets, the spacing is tighter, allowing for more opportunities. This mathematical approach is a key part of his risk management.
3. The "Tiny Profit, Many Times" Exit
Unlike trend followers who look for massive moves, the grid mindset requires taking small profits quickly. Yokoyama scales in with small sizes (0.01 lots) and takes profits as soon as the price retraces slightly . The goal is to accumulate many small wins to offset the infrequent, but inevitable, large losses that occur when the market does break out of the range.
A Unique Perspective: It's Not the Strategy, It's the Prep
The most overlooked aspect of Yokoyama's performance is the prep work. He didn't just pick a grid and start trading. He spent years "polishing his system to the extreme" . He knew exactly when to stop adding orders and, crucially, when to cut the entire grid if the market decided to trend.
This provides a critical lesson: the "Grid Trading Mindset" is less about the technical rules of the grid and more about the psychological discipline to follow your specific rules even when the market is testing you.
Conclusion
Nayuta Yokoyama's 1,376% return is a startling reminder that there is no single "right" way to trade. While the "trend is your friend" narrative is dominant, the "Grid Trading Mindset" offers a viable, albeit high-risk, alternative for those who can master its rules. It demands a specific type of patience—not the patience to wait for a trend, but the patience to grind out ticks in a noisy, chaotic market. As Yokoyama advises, "If you have a trading system, polish it to the extreme" .
