I can recommend SierraChart.
Togehther with IB that is a highly cost-efficient combination. Sierra support not one Second charts but two second charts ( as smallest). Two seconds is the smallest unit you store and show. But the realtime update is going on in 200ms intervalls on the chart. The is a data provider available for good historical data in two second increment special for SierraChart
