AI Assistant
The Vantixs AI Assistant is an AI-powered co-pilot built into the Strategy Builder. It helps you design, analyze, and fix trading strategies through a natural-language chat interface --- no manual required.
During the BETA period, the AI Assistant is available to all users. It works alongside backtesting and paper trading features. Live trading with real capital is planned for a future release.
Overview
The AI Assistant sits inside the Strategy Builder and has full awareness of your current canvas --- the nodes, connections, indicator settings, and validation state. You can ask it questions, request strategy modifications, or let it diagnose and fix problems.
It is powered by LangChain + LangGraph on the backend, using a tool-calling agent architecture. The AI can read your canvas, suggest changes, build strategies from descriptions, and surface actionable next steps.
Getting Started
The Floating Button
In the Strategy Builder, a floating sparkle button appears in the bottom-right corner. Click it to open the AI Assistant panel.
Quick Start Actions
When you first open the panel, a set of quick-start actions is displayed:
Quick Start Actions
Create SMA Crossover
Ask the AI to build a complete SMA crossover strategy on your canvas
Add RSI Indicator
Request an RSI indicator node added to your current canvas
Set Up Stop Loss
Ask the AI to add stop-loss protection to your existing strategy
Analyze Strategy
Have the AI review your current canvas for issues and improvements
Click any quick-start button or type a message in the chat input to begin.
Capabilities
The AI Assistant handles 9 specialized intent types, each focused on a different aspect of strategy building:
| Intent | What It Does |
|---|---|
| root | General-purpose assistant for open-ended questions and guidance |
| ANALYST | Analyzes your current strategy, identifies weaknesses, and suggests improvements |
| ARCHITECT | Designs strategy architectures and recommends node layouts for your goals |
| AUDITOR | Reviews your pipeline for logical errors, missing connections, and best-practice violations |
| FIXER | Diagnoses and resolves pipeline validation errors automatically |
| BACKTESTER | Helps configure backtest parameters and interpret results |
| TUTOR | Explains trading concepts, indicator behavior, and strategy patterns |
| CREATOR | Builds complete strategies from natural-language descriptions |
| RISK_MANAGER | Advises on position sizing, stop-loss placement, and risk parameter tuning |
The AI automatically selects the right intent based on your message. You do not need to specify which mode to use.
Strategy Design Suggestions
Describe what you want to trade and the AI will recommend a node layout:
- "Build a mean reversion strategy for ETH using Bollinger Bands and RSI"
- "Create an ICT order block strategy with multi-timeframe confirmation"
- "I want a momentum strategy that enters on MACD crossover and exits on RSI overbought"
The AI generates the node graph, places it on your canvas, and explains the logic.
Parameter Optimization Hints
Ask the AI about indicator settings and it will provide context-aware recommendations:
- "What RSI period should I use for 15-minute BTC charts?"
- "Are my Bollinger Band settings too tight for this timeframe?"
- "Suggest better EMA periods for my crossover strategy"
Node Connection Recommendations
The AI understands port types and data flow between nodes. It can suggest how to wire nodes together and flag incompatible connections.
Auto-Fix for Validation Errors
When your pipeline has validation errors (shown in the validation panel), the AI can diagnose and propose fixes. It reads the error context, understands which nodes and connections are involved, and suggests specific corrections.
Workflow Progress Tracking
For complex operations that involve multiple steps (e.g., building a full strategy from scratch), the AI displays a workflow progress indicator showing each step's status --- pending, in progress, completed, or error. This gives you visibility into what the AI is doing behind the scenes.
Chat Interface
The AI Assistant panel includes:
- Resizable window: Drag the edges to resize the panel on desktop
- Message history: Full conversation history with syntax-highlighted code blocks
- Copy support: Copy any AI response to your clipboard
- Scroll-to-bottom: Jump to the latest message when scrolling through long conversations
- Typing indicator: See when the AI is processing your request
- Error recovery: Clear error banners and retry failed requests
Tips for Effective Prompts
Be specific about your trading goals for the best results
- Good: "Create an RSI divergence strategy for BTCUSDT on the 4-hour timeframe with a 2% stop loss"
- Less effective: "Make me a strategy"
The more context you provide --- trading pair, timeframe, risk tolerance, indicators of interest --- the more tailored the AI response will be.
Technical Architecture
The AI Assistant uses a LangChain + LangGraph agent on the backend:
- Tool-calling agent: The AI can invoke structured tools to read your canvas, create nodes, connect ports, run analysis, and suggest actions
- Canvas awareness: Every request includes a snapshot of your current canvas state (nodes, edges, validation errors)
- Streaming responses: Messages stream in real-time via Server-Sent Events (SSE) for a responsive experience
- Circuit breaker protection: If the AI backend is temporarily unavailable, the system fails gracefully with a clear error message
