PVA (Price-Volume Analysis) is a technical analysis approach that studies the relationship between the price and trading volume of a financial asset. The core idea behind PVA is that trading volume can provide important information about the strength and direction of a trend, helping traders make more informed decisions.

-Increasing volume with rising price: Indicates a strong uptrend, and a green symbol (up arrow) is displayed.

-Increasing volume with falling price: Indicates a strong downtrend, and a red symbol (down arrow) is displayed.

-Decreasing volume with rising price: Indicates that the uptrend may be losing strength, and an orange alert (warning symbol) is displayed.

-Decreasing volume with falling price: Indicates that the downtrend may be losing strength, and an orange alert (warning symbol) is also displayed.

-If the volume is falling in an upward or downward movement, an alert mark (⚠️) is drawn.
