If the stock price first pulls back to the 257-260 zone (near MA10) before initiating a wide-grid position building, the risk-reward ratio would be more favorable. In the current high-level consolidation phase, a fine grid is better suited for capturing intraday volatility of 6-8%, but strict stop-loss protection is required.

Grid spacing: Wide grid ±10% (approx. ±26 CNY); Fine grid ±4% (approx. ±11 CNY)

Strong bullish alignment (MA5 > MA10 > MA30 > MA20), YTD gain of +91.4%

However, warnings from multiple resonances: extreme overbought conditions with BIAS at +23%, KDJ death cross at high levels (K 83.6 < D 86.0), and the combination of high AR with extremely low BR.

Significant short-term pullback risk exists, with MA10 (267 CNY) as the first key support. Risk Management: Given the stock's average daily amplitude of 6-8% and a 52-week maximum drawdown of 58% (374→155), it is recommended that total position size does not exceed 15-20% of personal investable assets, leaving ample margin.

Extreme Market Protection: A stop-loss line can be set 5% below the lower boundary (Wide grid 142 CNY / Fine grid 222 CNY). Once triggered, pause grid operations and wait for stabilization before re-evaluating.

Earnings/Event Window: Monitor the Q3 2026 earnings release date (expected late October). Pause grid operations around the earnings period to avoid gap risk.

Dynamic Center Adjustment: If the stock price continues to trade above MA20 for over 2 weeks, shift the center up to the latest MA20 value; if it breaks below MA30, shift the center down and widen the grid spacing.
