🔨 STEP 1: BUILD AI MODELS
Create machine learning models that learn patterns from years of stock market data. No coding required—just choose your settings and click Train.
🎯 What You Choose:
- Stock Universe: QB500, QB1000, NASDAQ-100, or sector-specific
- Training Regime: Bull markets, bear markets, sideways, recessions, expansions
- Target: What return to predict (3-day +2%, 7-day +5%, etc.)
- Features: Select from over 450+ technical, fundamental & macro indicators
- Algorithm: LightGBM, XGBoost, CatBoost, Random Forest
- Backtest Length: Standard walk-forward validation period
⚡ What Happens:
- Training (5-15 mins): AI analyzes thousands of stocks across years
- Pattern Detection: Finds relationships between indicators & price moves
- Validation: Tests model on unseen data to prevent overfitting
- Scoring: Generates performance metrics (accuracy, Sharpe, etc.)
⚡ STEP 2: PORTFOLIO BACKTEST YOUR STRATEGY
Before risking real money, test your model's picks against historical data. See how a $10,000 portfolio would have performed over the past year.
📊 Real Backtest Results - Pick The Best One:
You'll test multiple strategies. Here are 3 variations with different confidence thresholds. Notice how 45% confidence is the winner (better than 46%, which is still solid) but 42% confidence drops off a cliff.
✅ POINT-IN-TIME COMPLIANT BACKTESTS
Our backtests use Point-in-Time (PIT) compliant data, which means:
- ✓ Real Delisting History: Includes bankruptcies, buyouts, and delisted companies—not just "survivors"
- ✓ Historical Accuracy: Uses data as it actually existed at each point in time (no look-ahead bias)
- ✓ Realistic Results: Your backtest sees the same messy reality traders faced in real-time
⚠️ Note: Backtests do not account for commissions or slippage. Real trading costs will reduce your actual returns.
📈 STEP 3: TODAY'S PICKS
Every morning, your models analyze the current market and generate ranked predictions. Each pick shows confidence %, expected return, direction (long/short), and key metrics.
Low Confidence Day - Losses Avoided
When most picks fall below your confidence threshold (typically 45%), the system warns you NOT to trade. This day would have resulted in losses - see the red "Actual Return" column showing negative returns.
High Confidence Day - Better Returns
When picks hit 45%+ confidence, the model delivers strong signals. Check the green "Actual Return" column - multiple winners! This is when you want to be in the market.
🎯 Understanding Confidence
Confidence = how certain the model is. IMPORTANT:55% from Model A might be better than 90% from Model B. It's relative to each model's historical accuracy.
📊 Long vs Short
LONG: Expecting price to GO UP. Traditional "buy" trade.
SHORT: Expecting price to GO DOWN. Profit from decline (requires margin account).
