It is difficult see the current prices when placing an order, as prices move faster, like option prices move way faster. And we would work with limit order.
It would be nice to see depth in the buy/sell window itself. as buy/sell sidebar is wasting a lot of space. the depth can be easily accommodated in it.
See we can’t see the depth, the price is 461, but we don’t know what the current price is. So it will be useful while ordering limit orders.
