Ameritrade is turning off Streamer/Command Center later this week. I'm looking for some charting package that can show real-time bid/ask/trade with 10 second bars or even tick-by-tick values. Thinkorswim charts, as far as I can tell, can have bar size no shorter than 1 minute, and can show trade or bid or ask but not more than one simultaneously. Many traders can deal with 1 minute charts showing just trades, but I'm kind of used to the more detailed Streamer charts.
