The Bid Advisor analyzes four data signals for each COE category:

  • Price Trend (35%) — Compares average prices of the last 3 bidding rounds vs the 3 rounds before that. Falling prices are favorable.
  • Bid Ratio (30%) — The ratio of bids received to certificates available. A lower ratio means less competition.
  • Quota Supply (20%) — Whether the available quota is increasing or decreasing compared to recent rounds.
  • Seasonal Pattern (15%) — Historical tendencies (e.g., pre-CNY prices are typically higher, mid-year prices are typically lower).

Each signal is scored from -1 (unfavorable) to +1 (favorable) and combined into a weighted composite score. Scores above 0.3 are Favorable, below -0.3 are Unfavorable, and in between are Neutral.

Using the Bid Advisor Effectively

The Bid Advisor synthesises four data points into a single traffic-light signal for each COE category. It is designed to give you a quick read on whether current market conditions favour buyers, sellers, or neither — saving you the effort of tracking multiple data sources manually.

For the best results, combine the Bid Advisor's signals with your own research. Check the price trends for historical context, review the supply forecast for upcoming quota changes, and read our latest analysis for qualitative market commentary.

Frequently Asked Questions

How often is the Bid Advisor updated?
Signals are recalculated after every bidding round, typically twice a month. The analysis uses the latest available results, bid ratios, and quota data from the results archive.
Is the Bid Advisor financial advice?
No. The Bid Advisor is a data-driven tool for informational purposes only. It analyses publicly available data to highlight market conditions, but COE outcomes depend on many factors that cannot be predicted with certainty. Always do your own research before making a bidding decision.
What does a "Favorable" signal mean?
A favorable signal indicates that the weighted combination of price trend, bid ratio, quota supply, and seasonal pattern is pointing towards lower prices or weaker competition. It does not guarantee prices will fall — it means current conditions are historically associated with more buyer-friendly outcomes.
Why might all categories show the same signal?
When macro-level factors (such as a large quota increase or an economic downturn) dominate, all categories tend to move in the same direction. Category-specific signals differ most when supply or demand dynamics are uneven — for example, when Cat A quota rises but Cat B quota falls.
