Our forecasting system uses a specialized "Anchor & Offset" approach to provide a more accurate, reliable, and logical look at potential stock price movements. Instead of simply guessing the price, the model analyzes the behavior of the stock relative to its Opening Price each day.

Here is how to interpret your forecast to better understand potential price trends.

The Four Pillars of the Daily Forecast

Each day in your 30-day view provides four specific data points. Think of these as the "blueprint" for that day’s expected price action:

• Open (The Anchor): This is the baseline. We use the opening price as the starting point because it represents the market's reset button for the day.

• High (The Ceiling): The maximum level the stock is expected to reach. A rising "High" over several days suggests strong buyer momentum.

• Low (The Floor): The minimum level the stock is expected to dip toward. A rising "Low" indicates that the stock is finding stronger support as time goes on.

• Close (The Settlement): The final price of the day. This is the most critical value for determining if the overall trend for that day was positive or negative.

Understanding Our "Typical Price Deviation" Metric

To help you gauge the potential momentum of a stock, we use a specialized metric called the Typical Price Deviation (fap value above). This value tells you—in percentage terms—how much the stock is expected to "drift" from its current price point.

What is the "Typical Price Deviation"?

Each day, a stock moves through a range of prices (Open, High, Low, and Close). Instead of looking at just the closing price, we calculate the Typical Average Price by averaging these four values: {Open + High + Low + Close} / 4

Think of this as the "center of gravity" for the day's trading. It smooths out the noise and gives us a single, representative value for the day's activity.

What the "Typical Price Deviation" Tells You

Once we have the Typical Average Price, we compare it to the next day forecasted Open Price (the reference price) to calculate the Percentage Deviation. This results in a single value that represents the expected momentum for the day:

A Positive Value (+): The model expects the stock's "center of gravity" to shift upward. This is a bullish signal, suggesting the stock is likely to trade higher than the reference price.

A Negative Value (-): The model expects the stock's "center of gravity" to shift downward. This is a bearish signal, suggesting the stock is likely to trade lower than the reference price.

A Value Near Zero: The model expects the stock to remain relatively stable, trading sideways with minimal directional bias.

How to Use the Typical Price Deviation

You can use this percentage to quickly rank or filter your stock list:

• Filter for Opportunity: If you are looking for high-momentum stocks, look for those with the highest positive percentage values.

• Identify Support & Resistance: A large deviation indicates that the model expects a significant move. A small deviation suggests the model expects the stock to remain within its current range.

• Compare Across Assets: Because this value is expressed as a percentage, you can compare different stocks on an equal footing—even if one is a $10 stock and the other is a $500 stock.

How to Evaluate Market Sentiment

You can quickly gauge the outlook for any day in your forecast by comparing the Close to the Open:

• Bullish (Positive): If the Close is higher than the Open, the model expects buyers to control the day, resulting in a net price gain.

• Bearish (Negative): If the Close is lower than the Open, the model expects selling pressure to outweigh buying activity.

• Neutral/Consolidation: If the Close and Open are nearly identical, the model expects a day of indecision where the stock may trade sideways.

Gauging Volatility and Risk

The distance between the High and the Low (the "Range") tells you how volatile the model expects the day to be:

• Wide Range: Indicates high expected volatility. There is greater potential for movement, but also higher uncertainty.

• Narrow Range: Indicates low expected volatility. The model expects a calm, stable day with minimal price fluctuations.

Quality Assurance: Our "Clamping" Logic

You may notice that our forecast always maintains logical consistency—for example, the High will never be lower than the Open, and the Low will never be higher than the Open.

We apply an internal "Clamping Layer" to ensure that all daily predictions respect the fundamental laws of market behavior. This prevents the model from generating "impossible" prices, giving you a cleaner and more realistic set of data for your decision-making.

Tips for Success

1. Look for Trends in the "Close": Rather than focusing on one day, look at the 30-day trend of the Close price to see if the overall trajectory is moving up, down, or sideways.

2. Monitor the "Support" Levels: Watch the Low values. If the predicted Low begins to rise over several days, it often signals that the stock is finding a new level of support, which can be a bullish indicator.

3. Combine with Context: While our model identifies patterns based on historical data, it cannot predict sudden, unexpected news events (like earnings reports or global economic shifts). Use these forecasts as a statistical "map" to assist your analysis, but always pair them with your own research.
