Hey, I realized that whenever I buy 3 contracts of Soybeans say at 7.85 the system actually buys it at 7.87 and I lose money. When I sell, it sells at a price lower than what it should actually sell for.. Why is this happening? I feel like I'm being screwed over every f'in trade I make. I buy, the wave goes down, I sell, the wave jumps up. Wtf?
