To develop your custom indicators Overcharts has two programming languages: Overbasic and .Net (coming soon).

OverBasic is a basic style easy language. This means: ease of learning and power of development.
Slightly more complex than a scripting language, OverBasic provides the ability to create custom functions using all major syntax of a structured language (For, Do Until, If, Variables, Arrays etc). These features make it a powerful and versatile language suitable to create particularly complex indicators and trading systems.

Soon the .NET programming language (C#, Visual basic.Net) integrated with the Developer app will be available.
