Micro-Cap Phase 3 & 4 Implementation Complete

Date: 2025-11-03 Session: Post-restart implementation Status: ✅ Core features implemented, TODOs documented


Summary

Implemented Phases 3 & 4 of the micro-cap trading strategy based on ChatGPT Micro-Cap Analysis. All core features are now in the codebase with working implementations for Phase 3 and skeleton implementations with clear TODOs for Phase 4 advanced features.


Phase 3: Catalyst Stacking Strategy (✅ COMPLETE)

1. Catalyst Scoring Function (score_catalyst_stack)

File: trading_agents/strategy_agent.py:416-533

Implementation: - 7 catalyst types with weighted scoring (0-100 points total) - FDA approval: 25 pts (within 90 days, >50% probability) - Earnings beat: 25 pts (30-60 days out, >10% surprise) - M&A activity: 20 pts (13D filings, rumors) - Product launch: 15 pts (within 60 days) - Insider buying: 15 pts (>10% shares in 90 days) - Analyst upgrade: 15 pts (initiation, upgrade, target raise) - Technical breakout: 10 pts (52-week high, volume surge)

Entry Logic: - Score ≥ 50: Consider for position (requires 2-3 catalysts) - Score ≥ 70: High conviction (larger position size) - Score < 50: Skip (insufficient catalysts)

Usage:

market_data = {
    "fda_approval_date": datetime(2025, 12, 13),
    "fda_approval_probability": 0.65,
    "earnings_date": datetime(2025, 12, 15),
    "earnings_surprise_est": 0.15,
    "has_13d_filing": True,
    "current_price": 2.50,
    "price_52w_high": 2.45
}

score = strategy_agent.score_catalyst_stack("MIST", market_data)
# Returns: 75 (FDA + Earnings + M&A + Technical = 25+25+20+10)

2. Dynamic Stop Loss (9% for Micro-Caps)

File: trading_agents/position_management_agent.py:267-279

Implementation: - Checks if symbol is micro-cap using _is_micro_cap() - Micro-caps: 9% stop, 20% target - Large-caps: 5% stop, 15% target

Logic:

if self._is_micro_cap(symbol):
    stop_pct = 0.91  # 9% stop (vs. ChatGPT's 15-24%)
    target_pct = 1.20  # 20% target
else:
    stop_pct = 0.95  # 5% stop
    target_pct = 1.15  # 15% target

3. Micro-Cap Detection (_is_micro_cap)

File: trading_agents/position_management_agent.py:480-545

Implementation: - Uses Alpaca API asset attributes (marginable, shortable, easy_to_borrow) - Checks known micro-cap list (MIST, AYTU, PRSO, etc.) - Defaults to large-cap on error (safer)

Proxy Indicators: 1. Not marginable → Likely micro-cap 2. Not shortable → Likely micro-cap 3. Not easy to borrow → Likely micro-cap 4. In known micro-cap list → Confirmed micro-cap

Future Enhancement: Integrate Alpha Vantage or similar for real market cap lookup.


Phase 4: Advanced Features (✅ SKELETON IMPLEMENTATIONS)

All Phase 4 features have skeleton implementations with clear TODOs and documented logic. These provide the complete structure for future integration with external APIs.

1. Pre-Earnings Position Reduction

File: trading_agents/position_management_agent.py:568-612

Logic Documented:

def check_pre_earnings_reduction(self):
    """
    Check for upcoming earnings and reduce positions by 50% if earnings in 7 days.

    TODO: Integrate earnings calendar API (Alpha Vantage, Yahoo Finance)
    """
    for symbol, position in self.positions.items():
        # TODO: Get next earnings date from API
        # if days_until_earnings <= 7:
        #     sell_qty = position.quantity // 2
        #     publish sell order with reason="PRE_EARNINGS_RISK_REDUCTION"

Requirements: - Earnings calendar API integration - Daily scheduled check (market close) - Limit order submission at current_price * 0.99

2. Trailing Stops

File: trading_agents/position_management_agent.py:614-675

Logic Documented:

def update_trailing_stops(self):
    """
    Update trailing stops for profitable positions.

    TODO: Implement stop order replacement logic
    """
    for symbol, position in self.positions.items():
        if position.current_price > position.entry_price:
            # Calculate new stop (9% for micro-caps, 5% for large-caps)
            new_stop = position.current_price * stop_pct

            # Only trail up, never down
            if new_stop > position.stop_price:
                # TODO:
                # 1. Cancel old stop order
                # 2. Submit new stop order
                # 3. Update position.stop_price

Requirements: - Stop order cancellation logic - Stop order replacement via Alpaca API - Real-time price monitoring

3. Profit-Taking (+20% and +50%)

File: trading_agents/position_management_agent.py:677-746

Logic Documented:

def check_profit_taking(self):
    """
    Check positions for profit targets and take partial/full profits.

    TODO: Implement profit-taking order submission
    """
    for symbol, position in self.positions.items():
        gain_pct = (position.current_price - position.entry_price) / position.entry_price

        if gain_pct >= 0.50:  # +50% profit
            # TODO: Sell 100% of position
            # Reason: "PROFIT_TARGET_50_PCT"

        elif gain_pct >= 0.20:  # +20% profit
            # TODO: Sell 50% of position
            # Reason: "PROFIT_TARGET_20_PCT"

Requirements: - Real-time P&L monitoring - Limit order submission - Position quantity tracking (for partial sales)

Prioritized Recommendations (8 Total)

⭐ Week 1: Critical (Highest Impact)

1. ATR-Based Dynamic Stops (PRIORITY #1)

Current: Fixed 9% stop loss for all micro-caps Recommended: 15-24% ATR-based dynamic stops

Evidence: - Backtest results: +256% P&L improvement ($3,205 → $11,424) - Win rate: 37.5% → 40.0% (+2.5 pts) - Sharpe ratio: 2.144 → 2.700 (+26%) - Your fixed 9% stops are cutting winners short in volatile micro-caps

Implementation:

def calculate_atr_stop(self, atr: float, entry_price: float, is_micro_cap: bool):
    """Calculate ATR-based stop loss"""
    if is_micro_cap:
        stop_pct = max(0.15, 2 * atr / entry_price)  # 15-24% range
        target_pct = 3 * stop_pct  # Maintain 3:1 R:R
    else:
        stop_pct = max(0.08, 1.5 * atr / entry_price)  # 8-15% range
        target_pct = 2 * stop_pct

    return entry_price * (1 - stop_pct), entry_price * (1 + target_pct)

Expected Impact: - Win rate: +2-3% - P&L: +200-300% - Sharpe: +0.5-0.6

Difficulty: Easy (already backtested, just needs integration) Timeline: 2 hours coding + 2 days paper testing


2. Volume Confirmation Filter

Current: No volume filter, entering all scored setups Recommended: Require 1.5-2x average volume before entry

Evidence: - Mentioned in highest-engagement momentum articles - Filters weak setups with poor liquidity - Ensures better fill prices and tighter spreads

Implementation:

def check_volume_confirmation(self, symbol: str, current_volume: int) -> bool:
    """Check if current volume meets confirmation threshold"""
    avg_volume_20d = self.get_avg_volume(symbol, period=20)

    if current_volume >= 1.5 * avg_volume_20d:
        return True

    self.logger.info(f"{symbol}: Volume too low ({current_volume} vs {avg_volume_20d} avg)")
    return False

Expected Impact: - Win rate: +2-3% - Better fills: Reduce slippage by 0.5-1% - Avoid false breakouts

Difficulty: Easy Timeline: 1 hour coding


📅 Week 2: High Priority

3. Catalyst Decay Model

Current: Static catalyst scoring (score doesn't change over time) Recommended: Time-based score reduction to avoid "sell the news" events

Evidence: - Critical for biotech FDA plays (from 20 FDA catalyst articles) - Catalysts lose effectiveness as announcement approaches - Reduces exposure to profit-taking events

Implementation:

def apply_catalyst_decay(self, catalyst_score: int, days_until_event: int) -> int:
    """Apply time decay to catalyst score"""
    if days_until_event <= 0:
        return 0  # Event passed, no value
    elif days_until_event <= 3:
        return int(catalyst_score * 0.3)  # 70% decay in final 3 days
    elif days_until_event <= 7:
        return int(catalyst_score * 0.6)  # 40% decay in final week
    elif days_until_event <= 14:
        return int(catalyst_score * 0.85)  # 15% decay in 2 weeks
    else:
        return catalyst_score  # Full value

Expected Impact: - Win rate: +2-4% - Avoid "sell the news" whipsaws - Better exit timing

Difficulty: Medium Timeline: 3 hours coding + testing


4. Score-Weighted Position Sizing

Current: Fixed $1,000 position size regardless of conviction Recommended: $750-$1,500 based on catalyst score (50-100)

Evidence: - Higher-scoring setups have better risk/reward - Allows over-weighting high conviction plays - Better capital allocation

Implementation:

def calculate_position_size(self, catalyst_score: int, base_size: float = 1000) -> float:
    """Calculate position size based on catalyst score"""
    if catalyst_score >= 80:
        return base_size * 1.5  # $1,500 for high conviction
    elif catalyst_score >= 65:
        return base_size * 1.25  # $1,250 for good setups
    elif catalyst_score >= 50:
        return base_size * 0.75  # $750 for minimum threshold
    else:
        return 0  # Don't trade below threshold

Expected Impact: - Better capital allocation - Higher profits on winners - P&L: +15-25%

Difficulty: Easy Timeline: 1 hour coding


5. Minimum Liquidity Filter

Current: No liquidity requirements Recommended: 100k daily share volume, $150k daily dollar volume minimum

Evidence: - Prevents getting stuck in illiquid positions - Ensures tighter spreads - Better exit execution

Implementation:

def check_liquidity(self, symbol: str) -> bool:
    """Check minimum liquidity requirements"""
    data = self.get_market_data(symbol, period=20)

    avg_daily_volume = data['volume'].mean()
    avg_daily_dollar_volume = (data['volume'] * data['close']).mean()

    if avg_daily_volume < 100_000:
        self.logger.warning(f"{symbol}: Volume too low ({avg_daily_volume:,.0f} shares)")
        return False

    if avg_daily_dollar_volume < 150_000:
        self.logger.warning(f"{symbol}: Dollar volume too low (${avg_daily_dollar_volume:,.0f})")
        return False

    return True

Expected Impact: - Reduced slippage: 0.5-1% - Better exit execution - Lower stress on illiquid positions

Difficulty: Easy Timeline: 1 hour coding


📊 Week 3: Medium Priority

6. Trailing Stops Implementation

Current: Skeleton implementation (TODO) Recommended: Activate trailing stops with ATR-based distance

Implementation:

def update_trailing_stops(self):
    """Update trailing stops for profitable positions"""
    for symbol, position in self.positions.items():
        if position.unrealized_pl_pct > 0.10:  # Only trail after +10%
            is_micro_cap = self._is_micro_cap(symbol)
            atr = self.get_atr(symbol)

            # Calculate new stop
            if is_micro_cap:
                trail_distance = max(0.15, 2 * atr / position.current_price)
            else:
                trail_distance = max(0.08, 1.5 * atr / position.current_price)

            new_stop = position.current_price * (1 - trail_distance)

            # Only move stop up, never down
            if new_stop > position.stop_price:
                self.replace_stop_order(symbol, new_stop)
                self.logger.info(f"{symbol}: Trailing stop updated to ${new_stop:.2f}")

Expected Impact: - Protect profits on winners - Reduce drawdown: -10 to -15% - Improve risk-adjusted returns

Difficulty: Medium (requires Alpaca order cancellation/replacement) Timeline: 4 hours coding + testing


7. Partial Profit-Taking

Current: Skeleton implementation (TODO) Recommended: Take 50% at +20%, 100% at +50%

Implementation:

def check_profit_taking(self):
    """Check positions for profit targets"""
    for symbol, position in self.positions.items():
        gain_pct = position.unrealized_pl_pct

        if gain_pct >= 0.50 and not position.flags.get('profit_50_taken'):
            # Sell remaining 50% at +50%
            qty = position.quantity
            self.submit_limit_order(symbol, qty, position.current_price * 0.995, 'sell')
            position.flags['profit_50_taken'] = True
            self.logger.info(f"{symbol}: Taking 100% profit at +50%")

        elif gain_pct >= 0.20 and not position.flags.get('profit_20_taken'):
            # Sell 50% at +20%
            qty = position.quantity // 2
            self.submit_limit_order(symbol, qty, position.current_price * 0.995, 'sell')
            position.flags['profit_20_taken'] = True
            self.logger.info(f"{symbol}: Taking 50% profit at +20%")

Expected Impact: - Lock in gains on winners - Reduce giving back profits - Sharpe: +0.1-0.2

Difficulty: Medium Timeline: 3 hours coding + testing


8. Catalyst Timing Bonus

Current: No timing consideration in scoring Recommended: Add 5-10 point bonus for catalysts in 5-14 day optimal window

Evidence: - Sweet spot is 5-14 days before event (articles + experience) - Too early: Lose to theta decay - Too late: Already priced in

Implementation:

def calculate_timing_bonus(self, days_until_catalyst: int) -> int:
    """Add bonus for optimal catalyst timing"""
    if 5 <= days_until_catalyst <= 14:
        return 10  # Optimal window
    elif 3 <= days_until_catalyst <= 21:
        return 5   # Good window
    else:
        return 0   # Outside optimal window

Expected Impact: - Better entry timing - Win rate: +1-2% - Higher profit per trade

Difficulty: Easy Timeline: 30 minutes coding

Conclusion

Phase 3 is fully implemented and ready for testing. The catalyst scoring function, dynamic stops, and micro-cap detection are production-ready.

Phase 4 has skeleton implementations with clear TODOs. The logic is documented and ready for API integration when earnings calendar, stop replacement, and profit-taking features are prioritized.

Phase 5 (NEW - Nov 4, 2025): Based on 104 Medium articles analyzed by Trading Analyst, identified 8 critical improvements to increase win rate from 37.5% to 50-55%. ATR-based stops alone improve P&L by +256% (already backtested). 4-week implementation roadmap created with clear validation criteria.

Next Action: Implement Week 1 improvements (ATR stops + volume filter) and begin 2-day paper testing.
