How I combined GPT, Supabase, and advanced candlestick analysis to build the trading companion that revealed my psychological blind spots and finally broke my destructive patterns.


🧠 Why I Built Daily Wick

Like most traders, I discovered my true enemy wasn't the market—it was my own psychology.

After two years of inconsistent results, I reviewed hundreds of my trades and uncovered disturbing patterns:

  • I'd meticulously create trading plans, then abandon them mid-session when emotions took over
  • During winning streaks, I'd overtrade and give back profits
  • I'd exit profitable positions far too early, letting fear override analysis
  • My journaling became inconsistent exactly when I needed it most—during drawdowns

The revelation came after a particularly painful loss where I:

  1. Ignored my pre-defined risk parameters
  2. Doubled down on a losing position
  3. Abandoned my stop loss
  4. Watched in horror as my account took a 12% hit

The market hadn't beaten me—I had beaten myself.

Existing journals felt like glorified spreadsheets or simplistic note-taking tools with charts bolted on. None understood Inner Circle Trading methodology or addressed the psychology behind my decisions.

I needed something that would serve as both performance tracker and accountability partner—a system that would hold up a mirror to my trading behavior and help me recognize patterns I was blind to. When I couldn't find it, I realized I needed to build it myself.


šŸ› ļø Engineered for Trading Psychology

Every feature in Daily Wick is built around the unique demands of trading performance and psychology.

Rather than listing specific technologies, what matters is the why behind each component:

  • Responsive and intuitive design to remain functional under stress and distraction.
  • Real-time journaling capabilities that help capture insights before they fade.
  • Customized charting tools built to reflect key ICT concepts and multi-timeframe confluence.
  • AI-powered feedback loop that blends technical and emotional insight into actionable guidance.
  • Lightweight deployment ensuring the tool remains fast, even during volatile trading conditions.

The focus has always been aligning functionality with how traders actually think, feel, and operate under pressure.


āœļø Contextual Journaling: Capturing the Complete Picture

Daily Wick's breakthrough is its comprehensive approach to documenting the full trading experience. Each trade entry includes:

  • Technical Elements:

    • Standard metrics (ticker, entry/exit prices, position size)
    • Market structure identification
    • Key levels and timeframe analysis
    • Advanced ICT concepts applied
  • Psychological Components:

    • Emotional state before, during, and after execution
    • Energy levels and external stressors
    • Confidence rating with justification
    • Post-trade emotional impact assessment
  • Decision Framework:

    • Specific reasoning that triggered entry
    • Predefined exit parameters
    • Actual exit reasoning and deviation analysis
    • Alternative scenarios considered
  • Plan Adherence:

    • Verification against trading rules
    • Position sizing compliance
    • Session rules adherence
    • Risk/reward calculation accuracy
  • ICT Methodology:

    • Concepts applied (SMT, FVG, OB)
    • Confluence factors analysis
    • Disconfirming evidence considered
    • Market maker model predictions
  • Context Metrics:

    • Broader market conditions
    • Correlated instrument behavior
    • Session characteristics
    • News impact analysis

This holistic approach revealed patterns I'd never noticed despite years of trading:

  • My win rate drops 32% when trading during periods of personal stress or inadequate sleep
  • Trades entered following my morning routine outperformed others by 47%
  • Certain ICT setups (Order Blocks with FVG confluence) perform exponentially better with my execution style
  • My consistency disintegrates after 3 hours of active trading

The difference between "I bought AAPL at 180" and "I entered AAPL at 180 after confirming an order block with high confluence but felt anxious about upcoming earnings" is everything.


šŸ¤– Your AI Trading Coach: Personalized Feedback

Daily Wick's most transformative feature is its AI analysis system that identifies patterns impossible to see in your own trading. When you complete a trade entry, Daily Wick processes your data through a specialized GPT model that analyzes:

  1. Risk Management Execution
  2. Entry & Exit Decision Quality
  3. Technical Setup Validity
  4. Emotional Discipline Patterns
  5. Strategy Adherence Metrics

Sample feedback that transformed my trading:

"This marks your 7th consecutive trade during FOMC volatility. Your historical data shows an 83% loss rate in these sessions due to wider-than-normal stops not compensated by position sizing. I notice you entered despite documenting 'feeling uncertain' pre-trade. Consider implementing your 'high-volatility protocol' or sitting these sessions out entirely."

This isn't just record-keeping—it's having an experienced trading coach analyze every decision without emotional attachment.


šŸ“Š Visual Intelligence: Seeing Your Trading Clearly

Daily Wick transforms abstract trading data into actionable visual intelligence:

  • Multi-Dimensional Trade Analysis

    • Candlestick overlays with entries/exits
    • Time-of-day heatmaps
    • Position sizing vs. volatility
    • Emotional correlation mapping
  • Psychological Pattern Recognition

    • Emotional state outcomes
    • Rule violation trends
    • Best-performing ICT setups
    • Decision quality scores
  • Performance Evolution Tracking

    • Equity curve with discipline scoring
    • Drawdowns with psychological context
    • Behavior-improvement metrics
    • Custom goal tracking

A recent insight changed my approach:

"The 18 trades where you documented 'high confidence' showed a 78% win rate and 2.8 R:R. The other 24 trades showed only 29% win rate and 0.7 R:R."


šŸš€ Development Insights: Building for Traders

Creating Daily Wick taught me valuable lessons:

  • Start With Core Value: Even a minimal version improved discipline
  • AI Requires Context: Only worked after extensive custom prompting
  • Trader Psychology Dictates Design: UI must remain calm and intuitive
  • Data Structure Flexibility Is Crucial: Journaling needs constantly evolve
  • Community Testing Reveals Blind Spots: Customization needs vary greatly

The meta-lesson: building a tool to improve trading improves trading itself.


šŸŽÆ The Roadmap: Where Daily Wick Is Heading

Daily Wick's roadmap includes:

  • Advanced Mobile Experience
  • Personalized AI Coaching System

  • Deliberate Documentation
  • ICT Framework Application
  • AI-Augmented Awareness
  • Psychological Mastery

The most profound impact has been the transformation of trading from stress to self-awareness.
