You can try MultiCharts. http://www.tssupport.com/multicharts/ It is EasyLanguage compatible, and it has an Auto-Trade interface to IB. Caution: MC is still under development. Not all the EasyLanguage functionalities are completed yet. On the other hand, they have extended some of the EL capabilities. This program eventually will be more powerful than TradeStation.
You can lease the TradeStation8 software without opening an account. Then you can use TradeBullet to route the TS orders to IB.
