This ProBuilder code snippet demonstrates how to calculate a running volume total during specific trading hours. The code is particularly useful for markets like the ASX aus200, where trading volume outside of regular hours might not be relevant.

// cummulative volume for ASX aus200 Timezone
if Time < 095000 or Time > 163000 then
  vol=0
endif
vol=vol+volume
return vol coloured(285,165,32)style(histogram)

The code snippet provided performs a conditional check on the trading time and adjusts the volume calculation accordingly. Here’s a breakdown of how it works:

• Conditional Time Check: The if statement checks if the current time is before 9:50 AM (095000) or after 4:30 PM (163000). These times are likely chosen based on the specific trading hours of the ASX aus200.
• Reset Volume: If the condition is true (meaning it’s outside of the designated trading hours), the volume (vol) is set to zero. This prevents accumulation of volume data during non-trading hours.
• Accumulate Volume: If the time is within trading hours, the volume for each period is added to the running total (vol).
• Output: The final line returns the cumulative volume and applies a specific color (RGB: 285, 165, 32) and style (histogram) to the volume data on the chart. This visualization helps in quickly assessing the volume changes over the trading day.

This example is useful for understanding conditional statements and accumulation of data in ProBuilder, which can be adapted for various market analysis scenarios.
