Bad suggestion.
This program no bargain; it is still in beta. A lot of the features you had taken for granted in other programs, are either not ready, or not tried in real life trading. Furthermore, not all the EL is supported. And don't ask about autotrading, it is not ready yet. (even if they say it is working now, would you trust it with your real money?)
Just go to the support section of the website, you will see they are doing bug fix by trial and error.
The news gets worse if you plan to use IB as your datafeed. I know people who have QT and IBCharts with MultiCharts side by side. Both QT and IBCharts drew the charts quickly, but MultiCharts would sometimes hang there for hours, not knowing what to do. My friend called their tech support for help. Would you believe it, they blamed the problem on IB !!! How could it be when QT and IBCharts are working off the same datafeed? Their solution -- don't use IB and everything will be alright.
Compared with TradeStation, TradeStation has been around for ages (more than 10 years). The program has been tested in real life trading by professionals all over the World. It will take MultiCharts 5~6 years of further development to come up to speed to TradeStation.
Would you trade your real money on a beta program?
If you are not happy with TradeStation, the chances are, you will be even more frustrated with MultiChart.
