Two unusually large dark pool trades were detected in GDX stock in after hours trading on September 5, 2019.
These large dark pool trades were whale orders. Both dark pool trades were for 10.5 million shares of GDX at $29.31.
The dark pool trades look like buy orders because of how GDX responded immediately after the trades were reported by FINRA.
The other reason I think the large dark pool trades were buys is that they occurred right at significant support on the daily chart.
