#### **How it works**

1. **Choose a category**\
   Use the dropdown to filter markets by category (for example, Politics, Crypto, or Sports).
2. **Apply filters**\
   Adjust filters by:
   * **24H Volume**: find markets with high trading activity.
   * **Liquidity**: focus on markets with strong liquidity.
   * **Spread (%)**: identify markets with tight or wide spreads.
   * **Spread (Cents)**: narrow your search to markets within specific price ranges.
3. **Sort by metric**\
   Sort markets by Volum&#x65;**,** Liquidity, or Spread to find the best opportunities.
4. **Monitor results**\
   Use the table to analyze each market’s BID, ASK, Volume, and Liquidity values in real time.
5. **Save to Watchlist**\
   Add interesting markets to your personal Watchlist for quick access later.

#### **Example**

Suppose you want to find markets with the following parameters:

* Volume above **$1,000,000**
* Spread below **2%**
* Liquidity over **$500,000**

After applying these filters, the scanner will instantly display all active markets that meet your criteria, allowing you to act on opportunities in real time.
