This indicator is designed to provide visual and audible signals for traders by identifying specific momentum shifts in the market. It combines technical analysis with a time-based security feature, making it a systematic tool for spotting potential entry and exit points.

Core Analytical Logic

The script functions by monitoring two primary layers of technical data:

1. Stochastic Momentum Crossings The core of the logic relies on "Stochastic" oscillators—tools that measure whether an asset is overbought or oversold by comparing recent price movements to a specific range. The indicator tracks two lines within this oscillator (a Fast line and a Slow line).

  • Buy Signals: When the Fast line crosses upward over the Slow line, the script identifies a potential upward momentum shift.
  • Sell Signals: When the Fast line crosses downward under the Slow line, the script identifies a potential downward momentum shift.

2. Historical Signal Verification Unlike basic indicators that only look at the current moment, this script performs a deep-history analysis. It scans back over a large number of previous candles (defined by the "days" parameter) to calculate:

  • The frequency of bullish versus bearish signals.
  • The success rate of these signals compared to the actual price action that followed them. This historical data is processed internally to help determine the reliability of the current market trend.

Visual and Audible Alerts

To ensure traders do not miss critical movements, the script includes an active notification system:

  • On-Chart Markers: It places specific visual symbols (arrows) on the price chart at the exact moments where a bullish or bearish cross occurs.
  • Audio/Popup Notifications: When a significant crossover happens, the script triggers a sound file and displays a text alert on the screen, providing the current price for the trade.

Accessibility and Security Features

The script includes several user-friendly interface elements:

  • Expiration Logic: The tool features a built-in "validity" system. It checks the current date against a pre-set expiration date. If the date has passed, the indicator will display an expiration notice and disable its trading signals.
  • Information Labels: Upon loading, the script automatically generates labels on your chart to show the developer's information and provide status updates regarding the indicator's validity.
  • Customizable Parameters: Users can adjust how the data is calculated (such as choosing between "Simple" or "Exponential" smoothing) and choose which price data (High/Low vs. Close/Close) the logic should prioritize.
