Task Title  
Acquisition of Source Code and Usage Rights for Center EA (MT4 and MT5)  

Task Description  
I request the complete delivery of the source code for Center EA, developed for MetaTrader 4 (MT4) and MetaTrader 5 (MT5). This task includes the full transfer of usage, modification, and distribution rights for the code.  
The terms of the agreement are detailed below to prevent any misunderstandings or future disputes.  

1. Delivery and Validation Phases  
Demonstration and Preliminary Review  

- The Seller (Enrique Enguix) will provide the Buyer with a functional demonstration via a compiled .ex4/.ex5 file, clearly showing that the Expert Advisor operates as advertised.  
- This demonstration will not include the source code but only the necessary components for the Buyer to verify the operability and confirm that the product aligns with the offer.  
- After reviewing the demonstration, the Buyer must confirm whether they wish to proceed with the acquisition.  

Delivery of Complete Source Code  

- Only after the Buyer confirms their satisfaction with the demonstration will the Seller deliver the full editable source code (.mq4 and .mq5).  
- The source code will correspond to the latest published and functional version available on the MQL5 market, with no additional modifications or customizations.  

Final Review Period (3 Days)  

- Once the source code is delivered, the Buyer will have three days to verify that the material matches the demonstration.  
- During this period, the Buyer may only report functionality issues in the code relative to the prior demonstration.  
- Claims related to adaptations, strategy changes, or requests beyond the initial demonstration will not be accepted.  

Final Acceptance and Payment Release  

- If the Buyer does not report any functionality issues within these three days or explicitly accepts the delivery, the task will be considered complete and accepted.  
- Upon acceptance, the payment will be released to the Seller, and no refunds or further claims will be possible.  

2. Rights Transfer  

- Upon completion of this task, the Seller transfers all usage, modification, and distribution rights for the source code to the Buyer.  
- The Seller waives any future claims regarding the use of the code, provided the Buyer complies with MQL5 platform rules and applicable laws.  

3. Seller Guarantees  
The Seller guarantees that:  

- The code is their original work and does not infringe on third-party rights.  
- The delivered version is functional, as demonstrated during the review process.  
- It contains no malicious software, hidden limitations, or functions that impair its execution.  

4. Exclusions and Limitations  

- No Post-Sale Support: This task does not include support, maintenance, or future updates beyond the specified validation. Any additional services must be agreed upon separately.  
- Market Results and Risks: The Seller is not responsible for results obtained using the code in real or simulated markets.  
- Buyer Modifications: After delivery, the Buyer assumes full responsibility for any modifications or integrations made to the code.  

5. Payment Terms  

- The total task amount is $6,900, which will remain held by MQL5 until the Buyer confirms final delivery.  
- Once the delivery is confirmed, no refunds or disputes will be permitted, except in cases of clear non-compliance with the described conditions.  

6. Arbitration Protection  

- Partial Delivery and Preliminary Validation: The use of prior demonstrations ensures that the Buyer does not acquire the source code without first approving its conditions.  
- Invalid Claims: Claims made after acceptance will not be considered valid for arbitration if they pertain to:  
  - Changes, optimizations, or additional features not initially outlined.  
  - Unsatisfactory results in real markets or specific accounts.  
  - Support or assistance not covered in this contract.  

Conclusion: By accepting this task, both Buyer and Seller acknowledge that the delivered content meets the agreed requirements. Any disputes arising outside these terms may be dismissed in an arbitration process.
