Multi-Exchange Trading Status Report
Issue: “Still no kraken connection or trade” + Coinbase rate limiting
Executive Summary
Current Situation: The bot is experiencing API rate limiting on Coinbase while Kraken remains disconnected due to missing credentials. This creates a single point of failure where all trading load falls on Coinbase, exacerbating rate limit issues.
Impact:
- ⚠️ Coinbase API health at 48% with batch size reduced to 5 markets
- ❌ Circuit breaker triggering after 4 errors (30s cooldown)
- ❌ Kraken NOT connected (cannot distribute load)
- ✅ Alpaca IS running (Cycle #9 shown in logs)
Solution: Configure Kraken credentials to enable multi-exchange trading and distribute API load.
Detailed Status by Exchange
1. Coinbase Advanced Trade
Status: ✅ CONNECTED but ⚠️ RATE LIMITED
Symptoms:
2026-01-12 10:38:27 | WARNING | ⚠️ API health low (48%), using reduced batch size=5
2026-01-12 10:38:27 | INFO | 📊 Market rotation: scanning batch 70-75 of 12337 (1% through cycle)
Error fetching candles: {"message": "too many requests."}
2026-01-12 10:38:29 | ERROR | 🚨 GLOBAL CIRCUIT BREAKER: 4 total errors - stopping scan to prevent API block
2026-01-12 10:38:29 | ERROR | 💤 Waiting 30s for API to fully recover before next cycle...
Root Cause:
- Scanning 732+ cryptocurrency markets on single exchange
- Even with reduced batch size (5 markets), rate limits being hit
- API health degraded to 48% from accumulated errors
- Circuit breaker protecting against full API ban
Current Mitigation:
- Adaptive batch sizing (reduced from 15 to 5 markets per cycle)
- 8-second delay between market scans (was 6.5s, increased for better rate limiting)
- Circuit breaker stops scanning after 4 errors
- 30-second cooldown period before retry

- Rate limiting:
bot/trading_strategy.py lines 19-43
- Circuit breaker:

- Adaptive batching:
bot/trading_strategy.py lines 46-49
2. Kraken Pro
Status: ❌ NOT CONNECTED
Reason: API credentials not configured
Evidence:
- Environment variables not set:
KRAKEN_PLATFORM_API_KEY, KRAKEN_PLATFORM_API_SECRET
- Bot logs show:
⚠️ Kraken credentials not configured for MASTER (skipping)
- Code gracefully skips Kraken connection when credentials missing
Impact:
- Cannot distribute trading load across multiple exchanges
- All market scanning falls on Coinbase (causing rate limits)
- Missing diversification benefits of multi-exchange trading
Solution: See “Quick Fix” section below
Code References:
- Kraken broker:
bot/broker_manager.py lines 3255-3847
- Connection logic:
bot/broker_manager.py lines 3312-3574
- Credential check:
bot/broker_manager.py lines 3328-3357
3. Alpaca Markets
Status: ✅ CONNECTED and RUNNING
Evidence from logs:
2026-01-12 10:38:28 | INFO | 🔄 alpaca - Cycle #9
2026-01-12 10:38:28 | INFO | alpaca: Running trading cycle...
2026-01-12 10:38:28 | INFO | 🔍 Enforcing position cap (max 8)...
Trading Status: Active (on Cycle #9)
Notes:
- Alpaca is for stock trading, not cryptocurrency
- Running in parallel with Coinbase
- Demonstrates multi-broker trading is working when credentials are provided
Suppressing the Single Exchange Warning
If you prefer to use only Coinbase and want to suppress the single exchange trading warning, you can set an environment variable:
For Railway/Render Deployment:
- Go to your deployment platform dashboard
- Navigate to Variables or Environment Variables tab
- Add this variable:
SUPPRESS_SINGLE_EXCHANGE_WARNING = true
- Redeploy to apply changes
For Local Development:
- Edit
.env file in project root
- Add this line:
SUPPRESS_SINGLE_EXCHANGE_WARNING=true
- Restart bot:
./start.sh
Note: While this suppresses the warning, using multiple exchanges is still recommended for:
- Reduced API rate limiting
- Better trading resilience
- Access to more cryptocurrency pairs
Quick Fix: Enable Kraken Trading
Why This Helps
Enabling Kraken will:
- Distribute API load - Split market scanning across Coinbase + Kraken
- Reduce rate limiting - Each exchange has independent rate limits
- Increase resilience - If one exchange has issues, others continue trading
- Access more markets - Kraken has different cryptocurrency pairs
Step 1: Get Kraken API Credentials
- Go to: https://www.kraken.com/u/security/api
- Click “Generate New Key”
- Configure permissions (required for trading):
- ✅ Query Funds - Check account balance
- ✅ Query Open Orders & Trades - Track positions
- ✅ Query Closed Orders & Trades - Trade history
- ✅ Create & Modify Orders - Place trades
- ✅ Cancel/Close Orders - Stop losses
- ❌ Withdraw Funds - DO NOT ENABLE (security)
- Copy the API Key and Private Key (Secret)
For Railway Deployment (Recommended):
- Go to Railway project dashboard
- Navigate to Variables tab
- Add these variables:
KRAKEN_PLATFORM_API_KEY = <your-api-key>
KRAKEN_PLATFORM_API_SECRET = <your-api-secret>
- Click “Redeploy” to restart with new credentials
For Local Development:
- Edit
.env file in project root
- Add these lines:
KRAKEN_PLATFORM_API_KEY=<your-api-key>
KRAKEN_PLATFORM_API_SECRET=<your-api-secret>
- Restart bot:
./start.sh
⚠️ SECURITY WARNING:
- Never commit
.env file to git (already in .gitignore)
- Never share API secrets in logs, tickets, or screenshots
- Use IP whitelisting on Kraken API keys if possible
- Enable 2FA on your Kraken account
Step 3: Verify Connection
After configuring credentials and restarting:
Check logs for:
✅ KRAKEN PRO CONNECTED (MASTER)
Account: MASTER
USD Balance: $X.XX
USDT Balance: $X.XX
Total: $X.XX
Or run verification script:
python3 check_kraken_status.py
Expected output:
✅ Platform account: CONNECTED to Kraken
Balance: $X.XX USD / $X.XX USDT
Understanding the Architecture
Multi-Broker Independent Trading
The bot uses independent broker trading where each exchange operates in isolation:
Key Features:
- Each broker runs in its own thread
- Failures on one exchange don’t affect others
- Separate rate limiting per exchange
- Independent position tracking
- Automatic load balancing
Code Implementation:
- Main coordinator:
bot/independent_broker_trader.py
- Individual brokers:
bot/broker_manager.py (CoinbaseBroker, KrakenBroker, etc.)
- Strategy integration:
bot/trading_strategy.py lines 146-370
How Brokers Are Discovered
On startup, the bot:
- Attempts to connect to each configured broker (Coinbase, Kraken, OKX, Binance, Alpaca)
- Checks for credentials in environment variables
- If credentials found, attempts connection with retry logic
- If credentials missing, gracefully skips that broker (no error)
- Only connected brokers participate in trading
From logs:
📊 Attempting to connect Coinbase Advanced Trade (MASTER)...
✅ Coinbase MASTER connected
📊 Attempting to connect Kraken Pro (MASTER)...
⚠️ Kraken credentials not configured for MASTER (skipping)
📊 Attempting to connect OKX (MASTER)...
⚠️ OKX credentials not configured (skipping)
Rate Limiting Strategy
Coinbase Limits:
- ~10 requests/second burst
- Sustained rate must be much lower
- Bot uses 8-second delay between market scans (0.125 req/s)
- Adaptive batch sizing (5-15 markets per cycle)
With Kraken Enabled:
- Markets split between exchanges
- Example: 730 markets / 2 exchanges = 365 markets each
- Cuts Coinbase load in half
- Each exchange stays well under rate limits
Circuit Breaker:
- Monitors error count across all API calls
- Stops scanning after 4 errors (configurable)
- 30-second cooldown before retry
- Prevents permanent API bans

- After: Coinbase + Kraken each scanning ~365 markets (7-8 per cycle)
- Result: Halved API load per exchange, reduced rate limiting
Troubleshooting Guide
Issue 1: “Invalid nonce” errors on Kraken
Symptoms:
❌ Kraken connection test failed: EAPI:Invalid nonce
Cause: Nonce issues in multi-instance or rapid request scenarios
Solution: Already fixed in code!
- Custom nonce generator with microsecond precision
- Random offset on initialization (prevents collisions)
- Progressive nonce jumps on retries
- Thread-safe nonce generation
Code Fix: bot/broker_manager.py lines 3291-3450
Issue 2: “Permission denied” on Kraken
Symptoms:
❌ Kraken connection test failed: EGeneral:Permission denied
Cause: API key doesn’t have required permissions
Solution:
- Go to https://www.kraken.com/u/security/api
- Find your API key and click “Edit”
- Enable all required permissions (see Step 1 above)
- Save and restart bot
Issue 3: Still seeing rate limits after Kraken connection
Possible Causes:
- Both exchanges hitting limits simultaneously
- Market scan batch size too large
- Scan delay too short
- Other API calls (balance checks, position queries) adding to load
Solutions:
- Reduce
MARKET_BATCH_SIZE_MAX in bot/trading_strategy.py (currently 15)
- Increase
MARKET_SCAN_DELAY (currently 8.0s)
- Enable additional exchanges (OKX, Binance) to further distribute load
- Monitor API health score in logs
Issue 4: Kraken connected but not trading
Check:
- Is Kraken account funded? Minimum $1.00 required
- Check logs for balance:
USD Balance: $X.XX
- Verify trading cycle is running:
🔄 kraken - Cycle #X
- Check for errors in trading cycle
Common Issues:
- Underfunded account (< $1.00)
- API key permissions insufficient
- Markets not matching (Kraken uses different pair names)
