I hate MultiCharts. Not good UI/UX. Also, I prefer C# to easyLanguage. NinjaTrader would be better, or IQBroker, or ProTrader, all C# based apps. As a rule of thumb, for algo trading, stay away from 'easy' scripting languages, with the exception of Python or Lua. All these scripting languages are only good for automated trading based off technical indicators, and 'good' is a generous term when applied to these languages.
For algo trading, you need a language that has solid math and neural net libs available: Python, Lua, or C#, or Java/Scala/Clojure, Julia, R, etc.
