‘Seeing thousands of rapid, small-volume transactions on a single stock is usually driven by algorithmic trading, high-frequency market makers, and retail day traders. Instead of one person buying 10,000 shares at once, computers break massive institutional orders into tiny slivers to hide their intentions and minimize market impact.This high volume of fractional or small trades happens for several specific reasons:Algorithmic Slicing (VWAP/TWAP): Large institutions and funds use Volume-Weighted Average Price (VWAP) or Time-Weighted Average Price (TWAP) algorithms. They break down huge block trades into thousands of smaller transactions distributed throughout the day to avoid dramatically moving the stock price.High-Frequency Trading (HFT): Market makers and algorithmic trading firms constantly adjust their positions to maintain liquidity. They may buy and sell thousands of tiny lots (such as 1-share or 100-share blocks) within milliseconds to profit from microscopic price discrepancies.Retail Day Traders: Many independent day traders use strict risk-management strategies, occasionally testing the waters or limiting their exposure by trading in very small, localized increments (e.g., 1 to 5 shares) to minimize risk while testing setups.Automated Order Book Splitting: If a resting limit order is for 100 shares and an incoming market order wants 101 shares, the system executes one transaction of 100 shares and a second transaction of 1 share.’
Not sure if this helps.
