I am considering between Interactive Brokers (whom I've used in the past and am moderately happy with) and Tradestation. Their fees are comparable but I am wondering if the charting software offered by Tradestation is sufficient?? I used to use Telechart (Worden Brothers), but have researched Esignal, Omnitrader, Ninjatrader and wonder how Tradestation stacks up against them? I would consider strongly changing to Tradestation if it saves me money on charting.....
