The Prompt
You are tasked with aligning the MQ5 Expert Advisor (EA) with a Pine Script indicator by replicating the indicator values and the entry/exit logic exactly. You will be provided with the MQ5 EA code and the Pine Script indicator code for reference.
Your objective is to analyze both pieces of code comprehensively, understand the calculation of indicator values and trading logic in the Pine Script, and then adjust or rewrite the MQ5 EA so that it produces the same indicator values and executes trades based on the identical entry and exit criteria.
**Steps:**
1. Carefully review the Pine Script indicator to understand how its indicator values are calculated, including any parameters, data references, or unique formulas used.
2. Examine the MQ5 Expert Advisor code to identify how the current indicator values and trading logic are implemented.
3. Map the indicator calculations from the Pine Script to their equivalents in the MQ5 MQL5 language, adapting any constructs as necessary.
4. Update or rewrite the MQ5 EA to replicate the exact behavior of the Pine Script, ensuring the same indicator outputs and trading signals.
5. Verify that entry and exit conditions in the MQ5 EA match those in the Pine Script, reflecting precisely the same logic flows.
6. Test the MQ5 EA where possible to confirm it behaves consistently with the Pine Script indicator.
**Output Format:**
Provide detailed notes comparing the Pine Script and MQ5 logic, specify all changes made, and supply the updated MQ5 EA code with clear comments explaining each modification and how it corresponds to the Pine Script logic.
**Notes:**
– Preserve variable names where meaningful to maintain clarity.
– Comment extensively on the conversion steps and any assumptions.
– Ensure all numeric parameters match between both scripts.
– Retain the original trading logic and do not introduce new strategies or rules.
– When differences or limitations arise, explain how you resolved them clearly.
– If you encounter ambiguous logic in Pine Script, describe the ambiguity and your approach to handle it.
You will be provided the relevant codes to facilitate this task.

How to Use This Prompt
- Paste both MQ5 and Pine Script codes.
- Review Pine Script indicator calculations and logic.
- Map Pine Script functions to MQL5 equivalents.
- Rewrite MQ5 code to match Pine Script exactly.
- Add detailed comments for all changes made.
- Output updated MQ5 code with comparison notes.
Tips for Best Results
- Review Pine Script Thoroughly: Carefully analyze the Pine Script’s indicator calculations, including all built-in functions, lookback periods, and data handling, as MQL5 may require explicit implementation of equivalent logic.
- Map Data Structures and Series: Identify how Pine Script’s time series arrays (like `close`, `high`, `low`) and custom variables are handled, and replicate this in MQL5 using arrays or buffers, ensuring proper indexing and initialization.
- Replicate Entry/Exit Conditions Exactly: Translate Pine Script’s conditional logic (e.g., `crossover`, `crossunder`) precisely into MQL5, accounting for bar-by-bar execution and avoiding off-by-one errors in signal generation.
- Validate Parameter Consistency: Ensure all input parameters (periods, multipliers, thresholds) match exactly between scripts, and adjust MQL5 calculations to use the same data types and rounding methods as Pine Script.
