p95 Jitter Monitor – Network Stability & Data Feed Diagnostics

Success in Order Flow trading relies on fast and consistent data delivery. The p95 Jitter indicator is a professional diagnostic tool for NinjaTrader 8 that measures the time variance (inter-arrival time) between incoming market data events. It helps traders identify network micro-latency and “data bursts” that can negatively impact execution.

What is p95 Jitter?

Traders often experience “chart freezing” or delayed order executions. Frequently, the culprit isn’t the broker, but network jitter. This indicator calculates the 95th percentile (p95), showing the maximum latency within which 95% of your data packets arrive.

If the p95 value is high, your data stream is inconsistent. For scalpers and Order Flow traders, this inconsistency can lead to “slippage” in decision-making and execution.

Key Features:

• Real-Time p95 Measurement: Provides the statistically significant 95% threshold in milliseconds (ms), rather than a misleading simple average.

• Burst Detection: Tracks and counts “burst events” where data arrival exceeds a user-defined threshold (e.g., 200ms).

• Visual Status Alerts: A discrete, color-coded text overlay in the top-right corner of your chart:

  • Lime Green: Excellent connection (<80ms)

  • Goldenrod: Warning / Average (80-150ms)

  • Red: Unstable data flow (>150ms)

• Customizable Data Filtering: Choose to monitor only Trade events (Last), Bid/Ask changes, or all incoming market data.

• Performance Optimized: Built with a high-efficiency “QuickSelect” algorithm and throttled updates to ensure zero impact on your platform’s performance.

Why Should You Use It?

1. System Diagnosis: Instantly verify if your VPS, internet connection, or data provider is underperforming.

2. Market Context: Understand if a sudden price jump was a real market move or a “data dump” where multiple packets arrived simultaneously after a delay.

3. Clean Interface: Non-intrusive design. It functions as an overlay on the price panel without adding unnecessary plots or cluttering your workspace.
