What is DDLM-69?
DDLM-69 is a live walk-forward probability engine for financial markets. It generates real-time directional probability signals (0–1) for a set of instruments using the López de Prado walk-forward backtest methodology. It is the signal source for AGILEra (AI CRM) and Staz Nexus (lead intelligence). Patent Pending US 63/889,131.
What does "walk-forward" mean?
A walk-forward backtest re-fits the model on each new bar of data, predicts the next bar, then advances the window — exactly mimicking live deployment. There is no look-ahead bias because the model never sees future data during fitting. This is in contrast to "full-period" backtests that fit on the entire history and then evaluate on the same data — a method that always produces unrealistically good results.
What methodology does DDLM-69 use?
The engine is built on Marcos López de Prado's framework from "Advances in Financial Machine Learning" (2018): triple-barrier labeling, purging and embargo to prevent leakage, fractionally differenced features for stationarity, and meta-labeling to filter low-confidence signals. All steps are walk-forward validated.
What instruments and markets are covered?
DDLM-69 currently covers a set of US equity and macro instruments. The exact universe is visible in the live dashboard after login. Coverage is expanded based on subscriber demand — email stazmediacorp@gmail.com to request instruments.
Is this financial advice?
No. DDLM-69 outputs are probability values from a statistical model. They are not investment recommendations, financial advice, or signals to buy or sell any security. All use of this platform is at your own risk. See /legal for the full risk disclosure.

US Provisional Patent Application 63/889,131 covers the walk-forward signal architecture and its application to pipeline probability scoring across the Staz Media product stack. Filing date: September 26, 2025. Hard conversion deadline: September 26, 2026.
Pricing & Access
What does the Free tier include?
Free accounts can view the live signal dashboard in read-only mode, see public probability values, and explore limited alert history. Full signal data, CSV export, Whale Tracker, and priority alerts require a Pro or Annual subscription.
What does Pro ($29/mo) include?
Full signal access across all instruments, Whale Tracker (large-position movement detection), Chronos AI forecasts, CSV export of all signal history, and priority alert notifications. Billed monthly, cancel any time.
What does Annual ($249/yr) include?
Everything in Pro, billed annually — $20.75/mo, saving 28% vs monthly. One annual receipt for accounting. Annual subscribers also receive early access to new instruments and methodology updates.
How do I cancel?
After login, click "Manage Billing" in the dashboard header. This opens the Stripe customer portal where you can cancel, change plans, or update payment details. Access continues until the end of the paid billing period.
Technical
How often are signals updated?
Signal updates are driven by the walk-forward loop. The engine runs on a scheduled cycle tied to market data delivery. Live status (LIVE / OFFLINE) and signal count are shown in the dashboard header bar. During market hours, signals update on each completed bar.
What data feeds power DDLM-69?
Market data is sourced via Polygon.io. Feature engineering and model inference run server-side. No client-side data collection occurs. Subscription and session data are stored in Supabase. Payments are handled by Stripe.
Is my data shared with anyone?
No. Session and billing data are stored in Supabase with service-role access only. Stripe handles payments — DDLM-69 does not store card numbers. No advertising pixels, tracking scripts, or analytics SDKs are loaded on any authenticated page.
How does authentication work?
Sessions use HMAC-signed cookies with timing-safe comparison. There is no OAuth or third-party SSO. Credentials are checked against the configured admin/guest env vars server-side. Sessions expire after 24 hours and must be renewed.
How do I report a bug or security vulnerability?
Email stazmediacorp@gmail.com with subject "Security:" for security reports (please include steps to reproduce). For general bugs, use subject "Bug:". We target acknowledgement within 24 hours.
