+===== Understanding Price Representation =====
+The WebSocket API provides prices exactly as published by the exchange, using a **decimal format**. However, understanding price movement requires knowledge of **minimum price increments** and **point value calculations**.
+===== Minimum Price Increment =====
+Markets do not trade at arbitrary price levels; instead, they move in predefined steps known as the **Minimum Price Increment**. This defines the smallest amount by which a price can change.
+For example, if a market has a **MinPriceIncrement** of **25**, price levels would move as follows:
+  * **4000.00**
+  * **4025.00**
+  * **4050.00**
+  * **4075.00**
+  * **4100.00**
+This ensures that all price movements align with the market’s allowed increments.
+*Reference:* The **MinPriceIncrement** field is found in the **MarketDetails** message.
+===== Converting Price Differences to Cash Value =====
+To determine the cash value of a price movement, use the **Point Value**. This represents the dollar value of a single price unit.
+Formula:
+''(Price2 - Price1) × PointValue = Cash Equivalent''
+Example:
+<code>
+  Price1 = 4200.00**
+  Price2 = 4225.00**
+  Point Value = 0.5**
+  (4225.00 - 4200.00) × 0.5 = 12.5
+</code>
+This means a move from **4200.00 to 4225.00** corresponds to **$12.50 per contract**.
+*Reference:* The **PointValue** field is found in the **MarketDetails** message.
