How much is QCharts going up? Their service has been fairly good recently, but they did seem to be lagging last week. Also, they continue to send out spurious zero ticks every 15 minutes or so on NYMEX, causing you to have to switch chart time frames. Very annoying.
The last time I used TradeStation was the ill-fated version 2000i, which was a total and complete disaster that screwed up my trading for months. Their customer service made IB look like Schwab. Maybe they have improved. Hard to believe they could get worse.
