SportX Gauge Indicator – User Guide #

Introduction #

The SportX Gauge Indicator is a predictive tool designed to give you a clear and intuitive sense of potential short-term price movements in sports betting markets on Betfair—especially useful in the moments leading up to the start of an event (pre-off).

The indicator combines multiple market signals—such as market margin, recent trading ranges, weight of money, and price momentum—to produce a dynamic needle gauge. This needle moves continuously to reflect the combined strength of bullish (price likely rising) or bearish (price likely falling) signals, helping you quickly assess market sentiment at a glance.

Important:
The SportX Gauge is disabled once an event turns in-play, as in-play market conditions become too volatile and unpredictable for reliable short-term forecasting.

How to Read the Gauge #

The gauge needle moves between 0 (bearish) and 100 (bullish):

• 0 (Fully Bearish): Strong indication the price might soon drop.
• 50 (Neutral): Balanced market sentiment, no strong directional signals.
• 100 (Fully Bullish): Strong indication the price might soon rise.

The gauge updates every 500 milliseconds (0.5 seconds) to reflect fast-changing market conditions pre-off.

⚙️ Customisable User Settings #

The gauge lets you tune precisely how sensitive it is to different market signals. Below is a clear description of each setting, allowing you to adjust the indicator to match your trading preferences or specific sports markets:

📌 1. Overround Settings #

• Overround Weight (0–100%)
  Controls how strongly changes in the bookmaker’s profit margin (overround) influence the gauge. Higher values emphasise market-wide margin signals.
• Overround Center (%)
  Defines the “neutral” overround percentage. For example, if set at 110%, any market margin above this number pulls the gauge bearish (down), and below this pulls bullish (up).
• Overround Sensitivity (%)
  Adjusts how much overround fluctuations affect needle movement. Lower sensitivity means smaller margin changes will have stronger effects, and higher sensitivity smooths these movements out.

📌 2. Range Settings #

• Range Weight (0–100%)
  Controls how strongly the price’s current position within its recent trading range moves the gauge needle. A higher weight means this factor has a stronger influence.
• Range Method (Individual or Peer-based)
  Choose how the indicator calculates range:
  • Individual: Compares current price only to this selection’s recent high/low.
  • Peer-based: Compares this selection’s range to other runners or participants, highlighting relative market strength or weakness.

📌 3. Weight of Money (WoM) Settings #

• WoM Weight (0–100%)
  Controls how much the gauge responds to imbalances between money waiting to back vs. lay. High weight means big back-side volumes push the gauge bullish, and big lay-side volumes push it bearish.
• WOM Inner Depth (ticks)
  How close to the current price the indicator examines resting volume. Lower numbers (e.g., 1–2 ticks) reflect immediate trading intentions.
• WOM Middle Depth (ticks)
  A medium distance from the current price, showing volume pools slightly further away.
• WOM Outer Depth (ticks)
  The farthest examined volume depth, capturing more strategic or longer-term money placements.

📌 4. Momentum Settings #

• Momentum Weight (0–100%)
  Determines how much recent price moves (typically over the last 2 seconds) influence the gauge needle. High momentum weight makes the gauge react quickly to recent trends.
• Momentum Ticks
  Defines how many price-tick moves over the recent period represent maximum momentum. Lower tick numbers (e.g., 1–2) mean the indicator responds strongly to small changes, higher tick numbers (e.g., 4–6) require bigger price jumps.

📌 5. Catalyst (Volume) Settings #

• Significant Volume
  Sets the trade size threshold at which a single large matched bet triggers a stronger gauge reaction. Larger trades above this threshold amplify market signals.
• Bullish Multiplier
  Determines how strongly a large back-side trade (buying pressure) pushes the gauge further upward (bullish).
• Bearish Multiplier
  Determines how strongly a large lay-side trade (selling pressure) pushes the gauge further downward (bearish).

📌 6. Additional Settings #

• Use Stored Trade Range (ON/OFF)
  When enabled, re-uses the last calculated trading range value rather than recalculating each tick. This smooths gauge movements, useful in slower or less volatile markets.

🏇 Recommended Settings for Horse Racing (Pre-Off) #

Horse racing markets, especially near the start of a race, experience rapid price changes, sudden momentum shifts, and quick large trades. A good baseline configuration is:

This setup ensures sensitivity to rapid movements without extreme needle volatility.

🎾 ⚽ Recommended Settings for Tennis & Soccer (Pre-Off) #

Tennis and soccer prices move more gradually before events begin, meaning a smoother, less reactive gauge is preferable:

These settings produce a stable indicator, helpful for observing subtle shifts rather than reacting to every small price fluctuation.

⚠️ Important Reminder (In-Play Limitations) #

The SportX Gauge Indicator is designed exclusively for pre-off market conditions. Once a market moves in-play, real-time betting volumes and price movements become too unpredictable and erratic, reducing the indicator’s accuracy and reliability.

As a safeguard, the gauge automatically hides itself when markets go in-play.
