service overview
Convert Existing Trading Software to a New Platform
Nordman Algorithms provides cross-platform conversion and migration of custom trading software, including indicators, automated strategies, Expert Advisors, scripts, dashboards, execution utilities, and other platform-specific tools. We work with existing projects that need to be converted, adapted, or rewritten for a different trading environment.
Cross-platform converting is rarely a line-by-line code translation. Trading platforms differ in programming languages, market-data models, order APIs, strategy lifecycle, charting systems, event handling, historical data, and available platform features. We analyze the original system, map its required behaviour to the target environment, rebuild the necessary components, and validate the converted version against the agreed functionality.
conversion scope
What Trading Software Can Be Converted?
Conversion can cover a single calculation or a complete trading workflow. The scope is defined by the functionality that must be reproduced on the destination platform.
Automated Strategies & Trading Bots
Expert Advisors, NinjaTrader strategies, cBots, Pine Script strategies, EasyLanguage systems, and other automated trading logic.
Scripts & Trading Utilities
Order-management scripts, scanners, execution utilities, chart tools, automation helpers, and platform-specific workflows.
Trading Panels & Dashboards
Trade panels, risk dashboards, account controls, monitoring interfaces, and other custom user-facing components.
Alerts & Signal Logic
Indicator alerts, strategy conditions, signal-generation rules, webhook workflows, and platform-specific event logic.
Complete Trading Systems
Projects combining indicators, automated execution, account logic, interface components, alerts, and external integrations.
conversion workflow
How Cross-Platform Conversion Works
This is the technical method behind every conversion project. The objective is not to make the target code look like the source code. The objective is to reproduce the required behaviour using the architecture and capabilities of the destination platform.
Analyze the Original System
We review calculations, parameters, signals, plots, alerts, entry and exit rules, trade management, state logic, data dependencies, and interface behaviour.
Map Logic to the Target Platform
We identify the equivalent target APIs, data sources, order model, event lifecycle, charting framework, and platform-specific implementation constraints.
Rewrite & Adapt
The required functionality is rebuilt in the target environment. Where direct equivalence is not possible, an alternative implementation is defined before development.
Compare & Validate
We compare calculations, signals, plots, settings, historical behaviour, and execution logic against the agreed reference and test the converted version on the target platform.
Refine Platform-Specific Behaviour
UI, alerts, data handling, order workflows, performance, and platform-native controls are adjusted so the migrated software behaves naturally in its new environment.
Deliver Source Code & Support
After final validation, the converted project is delivered with the agreed source code, installation guidance, and post-delivery support defined in the project scope.
platform adaptation & equivalence
Platform Adaptation & Functional Equivalence
Cross-platform conversion is not simple code translation. The goal is to preserve the required trading behaviour while adapting or rewriting the implementation around the destination platform's data, APIs, execution model, architecture, and interface.
Market Data
Tick data, bid/ask history, volume, order-flow information, bar construction, and historical availability can differ between platforms and brokers.
Trading & Order Models
Order types, hedging or netting, partial fills, account handling, strategy position state, and execution APIs require platform-specific logic.
Platform Architecture
Indicators, strategies, threading, callbacks, persistent state, lifecycle events, and communication components are structured differently.
Charts & User Interface
Plots, drawing objects, panels, alerts, inputs, and interactive chart controls often need to be redesigned for the destination platform.
Core principle: the goal is functional equivalence, not identical source code. Conversion may involve translating some logic, adapting other parts, and completely rewriting platform-specific components.
What We Preserve
The conversion specification defines the behaviour that matters in the original system and how it should appear or operate in the target environment.
Core calculations, conditions, and signal logic
Inputs, outputs, plots, alerts, and user controls where supported
Strategy rules, position management, and execution behaviour where technically reproducible
Historical behaviour and reference results used for validation
Where Adaptation May Be Required
Differences in tick history, volume data, order handling, broker behaviour, chart rendering, platform permissions, or missing APIs can require an alternative implementation. These differences are identified during the technical assessment before the scope is finalized.

beyond platform-to-platform
Trading Software Conversion Beyond Platform Languages
Not every migration needs to end on another trading platform. We can also assess projects that move platform-native logic into external software, or bring existing external code into a supported trading environment.
Trading Platform → External Application
Existing platform code can be assessed for rewriting in Python, C#, C++, or another suitable environment when the objective is external analytics, data processing, execution infrastructure, or a standalone trading application.
MQL4MQL5NinjaScriptPine Script→PythonC#C++
External Code → Trading Platform
Existing models, calculations, algorithms, or application logic written outside the target platform can be reviewed and adapted for native implementation in MT4, MT5, NinjaTrader, cTrader, TradingView, TradeStation, Quantower, or another supported destination.

Don't See Your Source Platform?
If your existing trading software runs on another platform, we can review its source code, functionality, APIs, data dependencies, and documentation to determine whether it can be converted or rewritten for one of our supported target platforms.

faq
Cross-Platform Conversion — Common Questions
Common questions about converting, migrating, and rewriting trading software between platforms.
Cross-platform conversion is the process of recreating existing trading software for a different trading environment. It can involve translating reusable logic, adapting platform-specific behaviour, migrating data or execution workflows, and rewriting components that depend on the source platform's APIs or architecture.
No. A trading platform migration usually requires more than syntax conversion. Market data, indicators, order handling, chart objects, lifecycle events, execution models, and platform permissions can differ significantly, so the target implementation is normally rebuilt around the destination platform.
Yes. MT4 to MT5 conversion can include indicators, Expert Advisors, scripts, panels, alerts, and other MQL4 projects. The required logic is reviewed and rewritten or adapted for the MT5 environment rather than treated as a simple file-format conversion.
Yes. MT5 indicators, Expert Advisors, and custom trading logic can be assessed for conversion to NinjaTrader. The project requires mapping MQL5 behaviour to NinjaScript, NinjaTrader's event model, market data, charting framework, and order-handling architecture.
Yes, when the Pine Script logic can be reproduced with the data and capabilities available on the target platform. TradingView indicators, strategy logic, visual calculations, and alerts can be reviewed for migration to MT4, MT5, NinjaTrader, cTrader, TradeStation, Quantower, and other supported destinations.
We currently do not offer conversion into Tradovate or Thinkorswim. However, existing Tradovate and Thinkorswim projects can be reviewed as source environments for conversion to supported target platforms. We also do not currently offer conversion into Interactive Brokers or DAS Trader.
Possibly. If the source platform is not listed, we can review the source code, documentation, available APIs, data dependencies, and reference behaviour to determine whether the project can be rewritten for one of our supported target environments.
Yes, subject to technical assessment. A conversion project can move platform-native logic into an external Python, C#, C++, or other suitable application, or adapt externally developed algorithms for a supported trading platform.
Sometimes, but feasibility depends on what can be documented and independently reproduced. Source code is the best reference. Without it, we need sufficient specifications, inputs, outputs, screenshots, test cases, and behaviour examples. We do not reproduce proprietary third-party software without appropriate authorization or rights.
The goal is to reproduce the agreed functionality as closely as the destination environment allows. Exact one-to-one behaviour may not be possible when platforms use different market data, broker execution, order models, charting features, or proprietary APIs. Any known limitations or required adaptations are identified during the project assessment.
Yes. Source code and full IP ownership are transferred on final delivery and full payment unless a different arrangement is agreed in writing for a specific project.
