Which market trend typically reflects the most significant peak in trading volume?

The last hour before closing typically reflects the most significant peak in trading volume due to several market dynamics at play. During this period, traders are often making final adjustments to their positions before the market closes, leading to increased buying and selling activity. Many institutional investors prefer to execute their trades in the final hour to ensure they are reflected in the day's closing price, which can influence their portfolio valuations.

Moreover, as the trading day comes to an end, there is often a heightened sense of urgency among retail traders and day traders to close out positions or capitalize on any last-minute movements. This buildup of activity results in a substantial increase in trading volume, marking the final hour as one of the busiest times in the market. The closing price is also particularly significant, which fosters additional trading as participants seek to influence or react to price movements right up until the end of the trading session.

The other time frames mentioned may have higher volume, but they do not consistently match the closing hour's levels. For instance, while the first hour after opening is typically busy as traders react to news and establish positions, it generally does not surpass or equal the volume seen in the last hour. Similarly, midday trading hours often experience a lull in activity as traders assess the market's direction
