Mid-day is very difficult if you are trading equities (ie. 11am - 2pm ET). During this time it's typically just bots trading with other bots. And the bots are hungry at this time, so if you stick your toe in the water, they will try to game your order.
During early morning or late afternoon, there is more institutional flow, which makes it easier to trade, as the bots are busy gaming the big boys.
