+# Randebu
+
+**Create Trading Bots Through Natural Conversation**
+
+Randebu is a web-based platform that allows traders to create and manage automated trading bots through simple chat interactions. No coding required.
+
+---
+
+## The Problem
+
+Trading bots like **OpenClaw** and similar platforms are powerful but come with a steep learning curve:
+
+- Complex configuration files
+- Requires understanding of trading strategies
+- CLI-based interfaces
+- Steep technical barrier for non-developers
+
+## The Solution
+
+Randebu lets you create trading bots by simply chatting:
+
+> "Create a bot that buys PEPE when it drops 5% and sells when it profits 10%"
+
+That's it. Randebu handles the rest.
+
+---
+
+## How It Works
+
+1. **Chat** - Tell Randebu what you want in plain English
+2. **Bot Created** - Randebu creates a configured trading bot
+3. **Backtest** - Test your strategy with historical data
+4. **Simulate** - Run a simulation with real-time data
+5. **Deploy** - Activate your bot on the blockchain
+
+---
+
+## Built on AVE Cloud
+
+Randebu is powered by **AVE Cloud Skills** - the same infrastructure used by professional trading teams.
+
+### AVE Skills Currently Integrated
+
+Randebu uses **AVE Cloud Skills** (the skill scripts from `ave-cloud-skill` repository) for data fetching:
+
+| Skill Script | Command | Purpose | Line in agent.py |
+|-------------|---------|---------|------------------|
+| `ave_data_rest.py` | `trending` | Get trending tokens | 218 |
+| `ave_data_rest.py` | `search` | Search tokens by keyword | 285 |
+| `ave_data_rest.py` | `risk` | Honeypot/risk analysis | 367 |
+| `ave_data_rest.py` | `token` | Get token details | 487 |
+| `ave_data_rest.py` | `price` | Get token prices | 509 |
+
+### AVE Integration Points
+
+The AVE skills are called through `_call_ave_script()` in `agent.py`:
+
+```python
+# agent.py - Calling AVE skill scripts
+def _call_ave_script(self, command: str, args: list) -> tuple[int, str]:
+    ave_skill_path = os.path.join(
+        repo_root, "ave-cloud-skill", "scripts", "ave_data_rest.py"
+    )
+    result = subprocess.run(
+        ["python3", ave_skill_path, command] + args,
+        ...
+    )
+```
+
+### Direct API Usage (Not Skills)
+
+These components use the AVE API directly (not through skills):
+- `backtest/engine.py` - Uses `AveCloudClient.get_klines()` for historical kline data
+- `simulate/engine.py` - Uses `AveCloudClient.get_klines()` for real-time kline data
+
+---
+
+## Further AVE Integration Opportunities
+
+### 1. Trading Execution (Priority: High)
+- **AVE Skills**: `trade-chain-wallet`, `trade-proxy-wallet`
+- **Use**: Execute trades directly from the bot (market orders, limit orders, TP/SL)
+- **Status**: Not yet integrated - this is the next major feature
+
+### 2. Real-Time Alerts (Priority: Medium)
+- **AVE Skills**: WebSocket streams (`data-wss`)
+- **Use**: Notify users when price hits targets
+
+### 3. Portfolio Tracking (Priority: Medium)
+- **AVE API**: `address/walletinfo` endpoint
+- **Use**: Show user's complete portfolio across chains
+
+### 4. Advanced Risk Analysis (Priority: Low)
+- **AVE Skills**: Extended token analysis
+- **Use**: More detailed honeypot detection, liquidity analysis
+

+
+## Tech Stack
+
+| Component | Technology |
+|-----------|------------|
+| Frontend | SvelteKit, TypeScript |
+| Backend | FastAPI, Python |
+| Database | PostgreSQL |
+| AI | MiniMax (extended thinking) |
+| Trading Data | AVE Cloud API |

+
+## Future Development Plan
+
+### Phase 1: Core MVP (Current)
+- [x] Chat-based bot creation
+- [x] Strategy configuration via conversation
+- [x] Backtest historical data

+- [ ] Community strategies
+- [ ] Premium features (for fees)
+
+---
+
+## Business Opportunity
+
+### Target Market
+
+1. **Retail Traders** - People who want to automate trading but can't code
+2. **Crypto Enthusiasts** - Active traders looking for easier tools
+3. **Small Funds** - Need automation without expensive developers
+
+### Revenue Model
+
+| Tier | Price | Features |
+|------|-------|----------|
+| Free | $0 | 1 bot, 50 chats, basic features |
+| Pro | $19/mo | Unlimited bots, backtests, simulations |
+| Enterprise | Custom | API access, priority support, custom integrations |
+
+### Competitive Advantage
+
+- **No-code** - Unlike OpenClaw, 3Commas, Cryptohopper
+- **Natural Language** - Describe strategy in plain English
+- **AVE Integration** - Built on professional-grade infrastructure
+- **Focused UX** - Simple, clean interface designed for beginners
+
+### Market Size
+
+- Crypto traders: 100M+ globally
+- Trading bot market: $1.5B+ by 2027

+# Open Issues

+## Frontend
+
+### Token Address Confirmation Dialog
+- **Priority**: High
+- **Status**: Open
+- **Description**: When user configures a trading strategy via chat and mentions a token (e.g., "buy PEPE"), the AI asks for the token contract address. The frontend should show a confirmation dialog allowing user to:
+  1. See the token the AI detected (PEPE)
+  2. Enter/confirm the BSC contract address
+  3. Save the strategy with the confirmed address
+
+**Related Files**:
+- Frontend: `src/frontend/src/routes/bot/[id]/+page.svelte`
+- Backend: `src/backend/app/services/ai_agent/conversational.py`
+
+**Acceptance Criteria**:
+- [ ] Modal/dialog appears when AI detects a token without address
+- [ ] User can enter the contract address (0x...)
+- [ ] Strategy is saved only after user confirmation
+- [ ] Clear error handling if address is invalid

+
+IMPORTANT CHAIN LIMITATION:
+- We ONLY support BSC (Binance Smart Chain) blockchain
+- If user asks about any other chain (Solana, ETH, Base, etc.), respond with: "Currently we only support BSC (Binance Smart Chain). All trading strategies and token searches are performed on BSC."
+- Never search or recommend tokens on other chains
+- The search_tokens tool defaults to BSC, never change this
+
+Your response must be valid JSON with exactly this structure:
+{
+  "thinking": "Your internal reasoning and analysis (what you're thinking about)",
+  "response": "Your actual response to the user (be concise and helpful)",
+  "strategy_update": null or {
+    "conditions": [{"type": "price_drop" | "price_rise" | "volume_spike" | "price_level", "token": "TOKEN_SYMBOL", "token_address": null, "threshold": number, ...}],

+    "risk_management": {"stop_loss_percent": number, "take_profit_percent": number}
+  }
+}
+
+Guidelines:
+- "thinking" should be detailed reasoning about the user's request
+- "response" should be conversational and clear
+- "strategy_update" should be populated ONLY when the user provides specific trading parameters (percentages, tokens, conditions, etc.)
+- IMPORTANT: When a token is mentioned, set "token_address": null and ask user to confirm the token address before saving. Your response should say something like: "I need to confirm the token address. Could you provide the contract address for [TOKEN]?"
+- If no strategy parameters are provided, set "strategy_update" to null
+- Be friendly, concise, and helpful in your response
+

+  "response": "Randebu is your AI trading assistant! It can monitor cryptocurrency prices and execute trades based on your configured strategies. Tell me your trading parameters and I'll set them up for you.",
+  "strategy_update": null

+
+Example 2 (token needs confirmation):
+User: "I want to buy PEPE when it drops 10%"
+{
+  "thinking": "User wants to buy PEPE. I need the token contract address to proceed. I should ask for confirmation.",
+  "response": "I'd be happy to set up a buy order for PEPE! However, I need to confirm the token contract address. Could you provide the BSC contract address for PEPE? (It usually starts with 0x...)",
