Before you start

What Runs Inside Each Platform, and What Runs Outside

Platforms differ in what their own language can do. That decides whether your project is a native tool, an external application, or both, and it shapes the scope and price.

Inside the platform strategies trade from the platform’s own language
Partly analysis runs inside; execution needs an external part
Outside the platform automation runs in your own application

API and data access depend on your broker, account type and permissions. We confirm them during the free technical assessment.

Choosing a platform

Not Sure Which Platform Fits Your Project?

The right environment depends on your situation more than on any ranking of platforms. These four things usually decide it.

Your broker and accountThe broker and account type decide which platforms and APIs you can use, and for prop accounts, what the firm allows.
The result you needChart analysis, fully automated execution, trade management and reporting often point to different environments.
Data and API accessMarket data rights, API permissions and platform limits decide what can run natively and what needs an external component.
What you already haveExisting code, indicators and tools you rely on are usually worth building around rather than replacing.

FAQ

Trading Platform Development Questions

Questions about choosing, combining and extending trading platforms.

Can you help me choose a platform for my trading project?

Yes. We look at your broker and account type, the result you need, the data and API access available to you, and any code or tools you already use. From there we explain which environment fits the project and what would run inside the platform versus in an external application.

Can you convert an existing strategy or indicator to another platform?

Yes. We rebuild the logic in the target platform’s language and check that calculations and signals match the original. Where the target platform lacks a feature or uses different data, we agree on the adjustment before development starts.

Can you connect signals and trades between different platforms?

Yes, where both sides provide a suitable interface. Signal automation carries alerts or messages from a source such as TradingView into an execution platform; a trade copier follows the trades placed on a source account. Several common routes are available as ready-made copiers.

Do you develop for platforms not listed here?

Often, yes. Send us the platform name and what you want to build. We review its scripting language, API access, and account requirements, and confirm whether we can take on the project before you commit to anything.
