On the market page, the Rule of Price-Suggesting governs how prices are suggested for both market and limit orders. This system dynamically evaluates current market conditions, including the state of the order book, market depth, and real-time pricing trends, to offer informed and competitive price recommendations for traders. By integrating these factors, the framework ensures efficient and transparent trading decisions.

### 🛒 For Buyers

When placing a buy order, the system will suggest the following prices:

**Market Order** — displays the **lowest Ask (selling) price** in the order book at the current time.

**Limit Order** — displays the **lower** of the two values for the market you are trading:

| Market         | Value 1                             | Value 2                            |
| -------------- | ----------------------------------- | ---------------------------------- |
| **Yes Market** | Lowest Ask (selling) price of *YES* | Highest Bid (buying) price of *NO* |
| **No Market**  | Lowest Ask (selling) price of *NO*  | Highest Bid (buying) price of *YES* |

### 🏷️ For Sellers

When placing a sell order, the system will suggest the following prices:

**Market Order** — displays the **highest Bid (buying) price** in the order book at the current time.

**Limit Order** — displays the **higher** of the two values for the market you are trading:

| Market         | Value 1                             | Value 2                            |
| -------------- | ----------------------------------- | ---------------------------------- |
| **Yes Market** | Highest Bid (buying) price of *YES* | Lowest Ask (selling) price of *NO* |
| **No Market**  | Highest Bid (buying) price of *NO*  | Lowest Ask (selling) price of *YES* |

The Rule of Price-Suggesting ensures that traders have clear and competitive price recommendations for both buying and selling, based on the real-time state of the order book. By referencing the lowest asks and highest bids dynamically, this framework aligns user actions with market conditions, enabling informed decision-making and streamlined trading.
