Timeframe Specification (Issue #365)

Status: ✅ IMPLEMENTED - Multi-timeframe analysis support with CLI integration Implementation Phase: Phase 1 - Core Configuration and CLI Tools Author: Claude Code Date: 2025-11-28

Overview

Issue #365 implements comprehensive timeframe support for the AutoGen-Trader system, enabling traders to analyze and trade on different timeframes from scalping (1-minute) to long-term positioning (monthly). This document covers the complete implementation, configuration, and usage.

What is a Timeframe?

A timeframe (or interval) represents the time period of each candle in technical analysis:

  • 1m = 1 minute (60 candles per hour)
  • 5m = 5 minutes (12 candles per hour)
  • 15m = 15 minutes (4 candles per hour)
  • 30m = 30 minutes (2 candles per hour)
  • 1h = 1 hour (24 candles per day)
  • 4h = 4 hours (6 candles per day)
  • 1d = 1 day (daily chart, ~252 candles per year)
  • 1w = 1 week (weekly chart)
  • 1M = 1 month (monthly chart)

Timeframe Categories

Strategy Timeframes Use Case Risk Level
Scalping 1m, 5m Micro trends, EA signals High
Day Trading 15m, 30m Intraday swings, trend following Medium-High
Swing Trading 1h, 2h, 4h Medium-term trends Medium
Position Trading 1d (recommended) Daily trends, strong signals Medium-Low
Intermediate 1w Weekly trends, major support/resistance Low
Long-term 1M Monthly trends, institutional moves Very Low

Architecture

Core Components

1. TimeframeConfig Dataclass (config_defaults/trading_config.py)

@dataclass
class TimeframeConfig:
    """Timeframe configuration for multi-timeframe analysis."""

    default: str = "1d"  # Default timeframe
    enabled_timeframes: list = None  # List of enabled timeframes

    def is_valid(self, timeframe: str) -> bool:
        """Check if a timeframe is valid."""

    def validate(self) -> bool:
        """Validate entire configuration."""

Features:

  • Default timeframe set to "1d" (validated best Sharpe ratio: 0.856)
  • 10 enabled timeframes by default (1m, 5m, 15m, 30m, 1h, 2h, 4h, 1d, 1w, 1M)
  • Validation methods for both individual timeframes and complete configuration
  • Easy to customize: enable/disable timeframes, change default

2. TimeframeManager (src/trading/timeframe_tools.py)

Core class for managing timeframe state:

class TimeframeManager:
    def __init__(self):
        """Initialize timeframe manager."""

    def get_current_timeframe(self) -> str:
        """Get currently active timeframe."""

    def set_timeframe(self, timeframe: str) -> Dict:
        """Set active timeframe with validation."""

    def get_available_timeframes(self) -> Dict:
        """Get timeframes grouped by trading style."""

    def validate_timeframe(self, timeframe: str) -> Dict:
        """Validate a timeframe string."""

    def list_timeframes(self, verbose: bool = False) -> Dict:
        """List all available timeframes."""

3. Agent Tools (src/trading/timeframe_tools.py)

AutoGen-compatible function tools for agents:

Tool Purpose Parameters Returns
get_current_timeframe() Get active timeframe None {"current_timeframe": "1d"}
set_current_timeframe(tf) Change timeframe timeframe: str Status dict
list_available_timeframes() List all TFs include_descriptions: bool List of timeframes
validate_timeframe(tf) Validate TF timeframe: str {"valid": bool, ...}
get_timeframe_recommendations() Get strategy recommendations None Grouped recommendations

4. CLI Commands (src/cli/timeframe_commands.py)

User-facing CLI interface:

class TimeframeCommands:
    def list_timeframes(self, verbose: bool) -> str
    def set_timeframe(self, timeframe: str) -> str
    def show_current_timeframe(self) -> str
    def show_timeframe_recommendations() -> str
    def validate_and_info(self, timeframe: str) -> str

5. CLI Integration (src/cli/cli_session.py)

Natural language command routing:

  • Detects timeframe-related user input
  • Routes to _handle_timeframe_request()
  • Supports flexible natural language phrasing

Configuration

Default Configuration

File: config_defaults/trading_config.yaml

strategy_parameters:
  timeframe:
    default: "1d"
    enabled_timeframes:
      - "1m"    # 1 minute - scalping/EA signals
      - "5m"    # 5 minutes - fast intraday trading
      - "15m"   # 15 minutes - standard intraday
      - "30m"   # 30 minutes - intraday swing trading
      - "1h"    # 1 hour - medium-term trading
      - "2h"    # 2 hours - medium-term swing
      - "4h"    # 4 hours - swing/position trading
      - "1d"    # 1 day - VALIDATED DEFAULT
      - "1w"    # 1 week - intermediate-term trends
      - "1M"    # 1 month - long-term positioning

Custom Configuration

To customize timeframes in trading_config.yaml:

strategy_parameters:
  timeframe:
    default: "4h"  # Change default
    enabled_timeframes:
      - "1h"
      - "4h"
      - "1d"       # Reduced set for faster backtesting

Usage

1. CLI Commands

Output:

📍 Current Timeframe
==================================================
  1d: 1 day - VALIDATED DEFAULT - best Sharpe (0.856)

Get Recommendations

> timeframe recommendations
> suggest a timeframe
> best timeframe for swing trading

Output:

📈 Timeframe Recommendations
==================================================

🎯 Scalping (Aggressive):
   1m, 5m

   15m, 30m
...

2. Agent Integration

Using with AutoGen Agents

from src.trading.timeframe_tools import TIMEFRAME_TOOLS

# Register tools with agent
agent = SomeAgent(tools=TIMEFRAME_TOOLS)

# Agent can then call:
# - get_current_timeframe()
# - set_current_timeframe("4h")
# - list_available_timeframes()
# - validate_timeframe("1h")
# - get_timeframe_recommendations()

Example Agent Usage

# Agent decides to use 4-hour timeframe for swing trading
response = agent.call_function("set_current_timeframe", {"timeframe": "4h"})
# Returns: {"success": true, "message": "Timeframe changed to 4h", "current_timeframe": "4h"}

# Agent lists available for user
recs = agent.call_function("get_timeframe_recommendations")
# Returns: {"recommendations": {...}, "default_recommended": "1d"}

3. VoterAgent Integration

The VoterAgent already has partial timeframe support. To use it:

from src.autogen_agents.voter_agent import VoterAgent

# Create agent with custom timeframe
agent = VoterAgent(timeframe="4h")  # Instead of default "1d"

# Or use config-based default
agent = VoterAgent()  # Uses "1d" from config

4. Indicator Functions

Technical indicators now accept timeframe parameter for documentation:

from src.trading_tools.indicators import calculate_macd, calculate_rsi

# The timeframe parameter is informational
macd_data = calculate_macd(prices, fast=13, slow=34, signal=8, timeframe="1h")
rsi_data = calculate_rsi(prices, period=14, oversold=30, overbought=70, timeframe="1h")

Note: Actual timeframe aggregation should be done on the data before calling indicators.

API Reference

TimeframeManager

from src.trading.timeframe_tools import TimeframeManager

manager = TimeframeManager()

# Get current
current = manager.get_current_timeframe()  # Returns: "1d"

# Set new timeframe
result = manager.set_timeframe("1h")
# Returns: {"success": True, "message": "...", "current_timeframe": "1h"}

# Validate
validation = manager.validate_timeframe("4h")
# Returns: {"timeframe": "4h", "valid": True, ...}

# Get recommendations grouped by strategy
recs = manager.get_available_timeframes()
# Returns: {"scalping": [...], "day_trading": [...], ...}

TimeframeConfig (from trading_config)

from config_defaults.trading_config import get_config

config = get_config()
tf_config = config.get_timeframe_config()

# Check if valid
if tf_config.is_valid("1h"):
    print("1h is enabled")

# List enabled
print(tf_config.enabled_timeframes)

# Validate entire config
if tf_config.validate():
    print("Config is valid")

Best Practices

1. Choose Right Timeframe for Strategy

If You Want To Use This Reason
Scalp (quick in/out) 1m, 5m See micro trends
Day trade (within day) 15m, 30m Balance noise vs signals
Swing trade (multi-day) 1h, 4h Capture medium trends
Position trade (hold weeks) 1d Strong signals, less noise
Institutional tracking 1w, 1M See major moves

2. Default is Validated

  • 1d (daily) is the default and has been validated with 0.856 Sharpe ratio
  • Use custom timeframes only if backtesting proves better results
  • Don't arbitrarily change without testing

3. Consider Data Requirements

Shorter timeframes require:

  • More frequent market data updates
  • More computational resources
  • More market noise/whipsaws
  • Higher slippage costs

Longer timeframes require:

  • More historical data for indicators
  • More patience (fewer trades)
  • But: fewer false signals

4. Multi-Timeframe Analysis

For professional trading, analyze multiple timeframes:

# Example: Trend on daily, entry on 1-hour
daily_trend = analyze(symbol, timeframe="1d")
entry_signal = analyze(symbol, timeframe="1h")

if daily_trend.is_bullish() and entry_signal.is_bullish():
    # High probability setup
    place_buy_order()

Testing

Unit tests are provided in tests/unit/trading/test_timeframe.py:

# Run all timeframe tests
pytest tests/unit/trading/test_timeframe.py -v

# Run specific test class
pytest tests/unit/trading/test_timeframe.py::TestTimeframeConfig -v

# Run with coverage
pytest tests/unit/trading/test_timeframe.py --cov=src.trading.timeframe_tools

Test Coverage

  • ✅ TimeframeConfig initialization and validation
  • ✅ TimeframeManager state management
  • ✅ Agent tool function calls
  • ✅ CLI command output formatting
  • ✅ Natural language intent routing
  • ✅ Invalid input handling
  • ✅ Integration between components

Performance Considerations

Memory

  • TimeframeManager maintains minimal state (single current timeframe)
  • Configuration is loaded once at startup
  • No per-symbol timeframe storage

Speed

  • Timeframe validation: O(1) - list lookup
  • Current timeframe access: O(1)
  • Agent tool calls: < 1ms

Future Enhancements (Phase 2+)

Potential future improvements (not in Phase 1):

  1. Per-Symbol Timeframes (#366)

    • Different symbols trade better on different timeframes
    • Auto-detection based on historical performance
  2. Timeframe Weighting (#367)

    • Weight signals from multiple timeframes
    • Higher-timeframe signals weighted more heavily
  3. Synchronized Multi-Timeframe (#368)

    • Aggregate data from multiple timeframes simultaneously
    • Ensure all candles close together for fair analysis
  4. Timeframe-Adaptive Indicators (#369)

    • Auto-adjust indicator periods based on timeframe
    • e.g., RSI period = 14 for 1d, but 7 for 1h

Technical Implementation Details

Global TimeframeManager Instance (Issue #445 Fix)

Important: All components must use the same global TimeframeManager instance to share state:

# CORRECT - Use the global getter
from src.trading.timeframe_tools import _get_timeframe_manager

manager = _get_timeframe_manager()  # Gets global singleton

# INCORRECT - Creates separate instance (won't share state)
from src.trading.timeframe_tools import TimeframeManager

manager = TimeframeManager()  # DON'T DO THIS

The CLI's TimeframeCommands and the strategy's get_current_timeframe() both use _get_timeframe_manager() to ensure they share the same state.

Data Fetching with Timeframe

The fetch_unified_market_data() function accepts a timeframe parameter:

from src.data_sources.tools import fetch_unified_market_data

# Fetch hourly bars
data = fetch_unified_market_data(
    symbol="SPY",
    start_date="2025-01-01",
    end_date="2025-01-31",
    timeframe="1Hour"  # Alpaca format: 1Min, 5Min, 1Hour, 1Day
)

Timeframe Format Conversion

User format ("1h") must be converted to Alpaca format ("1Hour"):

from src.trading.timeframe_tools import convert_to_alpaca_timeframe

user_tf = "1h"
alpaca_tf = convert_to_alpaca_timeframe(user_tf)  # Returns "1Hour"

Cache Keys Include Timeframe

Different timeframes are cached separately:

# Cache key: symbol + date_range + source + timeframe
# "SPY_2025-01-01_2025-01-31_alpaca_1Hour"
# "SPY_2025-01-01_2025-01-31_alpaca_1Day"

Troubleshooting

"Invalid timeframe" Error

❌ Invalid timeframe '99h'. Valid options: 1m, 5m, 15m, 30m, 1h, 2h, 4h, 1d, 1w, 1M

Solution: Check spelling and use only supported timeframes. Enable custom ones in config if needed.

Timeframe Not Changing

> change timeframe to 1h
❌ Invalid timeframe '1h'. Valid options: 1d, 1w

Cause: Custom enabled_timeframes in config doesn't include "1h"

Solution: Edit config_defaults/trading_config.yaml to add "1h" to enabled_timeframes

MACD/RSI Values Same Across Timeframes (Fixed in #445)

Issue: Changed timeframe but MACD/RSI values remain identical

Cause (fixed): CLI and strategy were using different TimeframeManager instances

Solution: Update to latest code - all components now use global _get_timeframe_manager()

Indicator Not Respecting Timeframe

Issue: Indicator output doesn't match expected candle frequency

Cause: Timeframe parameter on indicator functions is informational only - actual data aggregation happens upstream

Solution: Ensure data is aggregated to target timeframe BEFORE calling indicator functions
