Intraday GDB
TradersLab INTRADAY GDB Documentation
Overview
The Intraday GDB (Global Daily Breadth) feature in TradersLab provides real-time insights into market breadth and momentum throughout the trading day. By tracking price-breadth-momentum in major indices, traders can gauge the strength and direction of the market with precision.
Unlike traditional end-of-day breadth indicators, Intraday GDB helps short-term traders assess market conditions as they evolve, making it a powerful tool for intraday decision-making.
What is Intraday GDB?
Global Daily Breadth (GDB) is a TradersLab proprietory indictoror measuring the price-breadth-momentum behavior within a given market or index. The Intraday GDB tracks this measure in real time, updating continuously to reflect shifts in market sentiment, momentum, and overall participation.
Instead of relying on just price movement, Intraday GDB gives traders an X-ray view of market health by highlighting whether price action is supported by broad participation or driven by just a few stocks.
How to Use Intraday GDB for Trading
1. Assess Market Strength in Real Time
Positive GDB readings indicate broad market participation on the upside, suggesting a strong, sustainable rally.
Negative GDB readings suggest market weakness, with more stocks declining than advancing, increasing the likelihood of further downside.
Extreme GDB shifts often precede market reversals or confirm ongoing trends.
2. Spot Intraday Momentum Shifts
Divergences between price and GDB can be a strong signal.
If the market index is rising but GDB is falling, it suggests weakening internals and potential exhaustion.
If the market index is falling but GDB is improving, it signals potential accumulation and a reversal opportunity.
Sharp GDB inflections can indicate liquidity injections, rotations, or program trading events that traders should be aware of.
3. Identify High-Probability Trading Opportunities
Breakouts & Continuations: When GDB strengthens alongside a price breakout, it increases the probability of follow-through.
Mean Reversions: When price moves sharply but GDB remains steady, it may signal exhaustion and a high-reward mean reversion opportunity.
Intraday Trend Confirmation: If GDB remains strong through multiple sessions, it reinforces the trend’s reliability.
4. Compare Breadth Across Different Markets
TradersLab's Intraday GDB provides real-time GDB readings for major indices such as:
NYSE Composite (^NYA)
S&P 500 (RSP - Equal Weight)
Nasdaq 100 (QQQE - Equal Weight)
Russell 2000 (IWM - Small Caps)
By comparing the breadth across these markets, traders can identify which indices are leading or lagging, helping them position trades accordingly.
