Spread_mon_kyo
Download script
This tool is designed to monitor and display "spreads"—the difference between the buying and selling prices of various currency pairs—in real-time on a trading platform. It acts as a visual dashboard that allows traders to see how much it costs to enter various markets at any given moment.
Key Functionalities
Real-Time Spread Monitoring The script automatically tracks 14 different major currency pairs simultaneously. It fetches the current spread for each pair and displays the information clearly on your screen. Each pair is assigned a specific position on the dashboard, making it easy to read at a glance.
Visual Dashboard Instead of forcing you to click through different windows to check costs, this script creates a dedicated display area. It shows:
- The name of each currency pair.
- The current spread value in real-time.
- A clear visual indicator showing whether the logging feature is currently active.
Data Logging System One of the more advanced features is the ability to record this data into an external file (CSV format). If enabled, the script calculates and saves the following:
- Time Stamps: Records exactly when the data was captured.
- Average Spreads: It calculates a cumulative average for each currency pair based on the volume of updates processed. This allows you to analyze historical spread behavior over time.
- Automated Export: The logs are organized into a structured format that can be opened in spreadsheet software (like Excel) for further analysis.
How it Works Behind the Scenes
The logic follows a continuous loop:
- Scanning: It constantly checks the live market to grab the current spread for all 14 currencies.
- Updating: It refreshes the numbers on your screen instantly as the market fluctuates.
- Logging: Every time a new candle forms on the chart (specifically on a 1-minute timeframe), the script performs a "snapshot" of the data. If logging is turned on, it calculates the average spread and writes that information into a saved file on your computer.
- Cleanup: When you remove the tool from your chart, it automatically cleans up the visual elements to keep your workspace tidy.
Summary for the User
Essentially, this script serves as a market transparency tool. It eliminates the need to manually check individual charts to see transaction costs, providing you with a centralized "live feed" of spreads while also offering a way to archive that data for long-term performance tracking.
