Was watching HIG depth today as had a sell on some of my stock. Market was someone buying a 100 k on 6.0 with me at 6.3. When wompa a big shark came along and took out my bid in 2 chunky bits.Very strange. Last time a jump like that happened on big volume was January. Check out the chart to see what happened then.Something is up. Hold on to your stock for a look see. I jumped back in to buy at 6.1. Anyone know anything tangible ? Also having been a member of hot copper for maybe 15 years. I think it doesn't matter what we write it makes didly squat on the SP. There is a much bigger force than us out there. But sharing knowledge is good karma. Enjoy your weekend
