So I found a system with a product that was S/B at 15k. I leave to a system and buy the same product at 10k. I return to the first system to sell product at 5k profit and I am golden right?? Nope..within the 10 min I was gone the system at 15k S/b is now 10K S/B..so ZERO profit. Is this really had bad the market is or does the system adjust the prices based on what I bought no matter where to screw me over?
