Frequently Asked Questions


What is data rains?

Data Rains is an AI-powered daily forecasting system that analyzes over 500 assets—including stocks, commodities, and currencies—to predict directional movement in the market. Think of it like a weather forecast—but for the financial climate.

HOW DOES THE FORECAST WORK?

Each night, our proprietary engine—DopplerXGB 4000—ingests market data and news signals to generate forecasts using machine learning. We rank assets by their likelihood of moving up or down during the trading day, using two primary models:

  • XGBoost (gradient boosted decision trees)

  • LSTM (long short-term memory neural networks)

Their predictions are blended into a single ensemble score that reflects directional confidence.

What does the Percent next to each asset mean?

This is the forecasted probability that the asset will go up in price by the end of the trading day.

  • A score above 50% = expected increase

  • A score below 50% = expected decrease

  • The higher the number, the more confident the model is in its directional forecast

what is AUC? Why does it matter?

AUC (Area Under the Curve) measures the model’s ability to separate winners from losers.

  • AUC of 0.5 = no skill (random)

  • AUC of 1.0 = perfect separation

  • AUC above 0.60 = meaningful signal

  • AUC above 0.65 = high-quality forecast radar 📶

We display AUC scores alongside each forecast to give you insight into how confidently the model identified that signal.

what data powers the model?

Our forecast engine processes a variety of inputs daily, including:

  • Price/volume-based market features

  • Recent movement trends

  • News sentiment scores

  • Calendar effects (e.g., FOMC, earnings events)

  • Macroeconomic regime flags (risk-on / risk-off detection)

All of this is analyzed, preprocessed, and modeled using our in-house machine learning (ML) pipeline, which is retrained and validated regularly.

What does the DopplerXGB 4000 actually do?

It’s our tongue-in-cheek name for the model stack that powers our forecasts. But behind the weather-tech branding is a serious system:

  • XGBoost models rank directional potential

  • LSTM models pick up sequential/momentum trends

  • A blend of predictions + model confidence produces the final signal

  • AUC is used to measure signal clarity

This process is executed daily using NVIDIA RTX-powered computation and outputs clean, interpretable probabilities.

When is the forecast updated?

Forecasts begin to update every weekday starting at 6:30 PM EST and published before the opening bell at 9:30 AM EST.

Can i download the forecast?

Yes. Subscribers to the Full Market Access plan can download a CSV with the full daily signal set across 500+ assets since the historical start of tracking by Data Rains.

Each row includes:

  • Run Date

  • Predicted Date

  • Ticker

  • Predicted direction (% confidence)

  • AUC score (accuracy of model for each ticker)

  • Model class outputs (1=up, 0=down)
