Can y'all please explain this to me. For instance, with #CAL, the price for a share on icwealth is 0.79 and the buy and sell price is 0.78 and 0.79 respectively. When I try buying, it's being sold to me for 0.79 and when I'm trying to sell its it shows 0.79 but before you place your order, you'd be selling it at 0.78 instead. Why is that?
