You only count TRTC shares and GLDFF shares bought, while ignoring the dollar volume.
Most OTC investors don't buy massive dollar amounts at one sitting. Even the playing field to be "real" with a comparison. Start comparing dollars bought, not shares.
One share of TRTC at close equals 10.4 shares of GLDFF at close.
No wonder more "shares" sold of GLDFF than TRTC. Math.
