The Prompt
You are provided with an existing MQL5 code for a range breakout indicator. Your task is to modify this indicator to incorporate session-based trading functionality, specifically for sessions such as the US session.
The modifications must adhere to the following requirements:
– Add Logic: Detect and mark the first candle of the specified trading session (e.g., US session) within the current indicator.
– Mark High and Low: Identify and mark the high and low range of this first session candle, maintaining the same style and plotting behavior as the current indicator.
– Preserve Existing Functions: Do not modify or alter any existing plotting functions or the visual aspects of the indicator; only add the session detection and range identification logic.
– Unchanged Behavior: The overall behavior and output of the indicator, apart from the added session-based functionality, should remain unchanged.
# Steps
1. Identify Timeframe: Determine the timeframe and timing parameters corresponding to the desired session (e.g., US session hours).
2. Implement Detection: Detect the first candle within this session on each trading day.
3. Capture and Mark: Capture and mark the high and low of this first session candle, replicating the existing plotting method for range breakout.
4. Integrate Smoothly: Ensure the new code integrates smoothly without changing existing indicator plots or calculations.
# Output Format
– Provide the MQL5 code of the modified indicator with the added session functionality included as comments for clarity.
– Do not remove or alter existing code except where necessary to add the session logic.
– Preserve original code comments and structure as much as possible.
# Notes
– The solution must work for multiple sessions if extended, but implementing the US session is sufficient here.
– Ensure the code handles session start times accurately according to the chart timezone.
– Maintain performance efficiency and avoid redundant calculations.

How to Use This Prompt
- Copy the prompt provided above.
- Open your MQL5 editor or coding environment.
- Paste the prompt into the editor for reference.
- Follow the steps outlined in the prompt to modify the code.
- Test the modified indicator to ensure functionality.
- Save and document your changes for future reference.
Tips for Best Results
- Identify Session Hours: Define the start and end times for the US trading session (e.g., 14:00 to 21:00 UTC).
- Detect First Candle: Implement logic to check for the first candle of the US session each trading day.
- Mark High and Low: Capture the high and low of the first candle and plot them using the existing indicator’s style.
- Integrate Without Disruption: Ensure that the new session functionality does not interfere with the current indicator’s behavior or output.
FAQ
- What is a range breakout indicator?
A range breakout indicator identifies price levels where a currency pair breaks out of a defined range. - How do you detect the first candle of a session?
You check the time of each candle and compare it to the defined session start time. - What is the US trading session time?
The US trading session typically runs from 8:00 AM to 5:00 PM EST. - Why preserve existing plotting functions?
To ensure the indicator's original functionality and visual representation remain unchanged.
