Trade Copier from MT4 to MT5

Mandatory Requirements

• Development Requirements: This project must be completed within one day. To achieve this timeline, only developers who have prior experience with local trade copier development and already possess the relevant source code are encouraged to apply, as this is essential for minimizing development time.

• Source Code: The project must include the complete source code for both the MQL4 (MT4) and MQL5 (MT5) sides.
  

• Speed: The MT5 receiver must process trade information from the MT4 transmitter with a reaction time of approximately 0.05~0.1 seconds.  (should use EventSetMillisecondTimer)

• Only Copy Executed Orders: Copying TP, SL, limit, and stop orders is unnecessary. Only executed trades need to be transmitted. However, the system must include a mechanism to ensure no trade is missed, even when multiple orders (2-3 trades) are executed rapidly on the transmitter side.  (In other trade copiers, it has been observed that one or two orders are occasionally missed, which is considered a critical functional issue.)

• No Reverse Copy: Reverse trade copying is not required

• Multiplier: The receiver should support multipliers that can be assigned for each symbol mapping pair individually. This is necessary because the lot size ratio may vary between instruments, especially when working with different brokers. (For example, the proportional relationship between lot sizes for different instruments might not be consistent.) To simplify configuration, each multiplier should be written as part of the symbol mapping.

• Symbol Mapping: A 1:1 mapping between symbols on the transmitter and receiver is required, with the ability to specify individual multipliers for each symbol pair during the mapping process.

• Async Order Execution: Orders on MT5 should utilize OrderSendAsync for faster execution.

• Partial Closures: The transmitter's partial closures must reflect accurately in the corresponding MT5 positions, referencing the transmitter's ticket number for matching.

While the above requirements are mandatory, the developer's suggestions are welcome for additional features, user interface design, and INPUTS configuration. There is considerable flexibility to incorporate ideas that enhance functionality or improve user experience.

Considering the prior effort invested in similar projects, the additional mandatory requirements, and the focused attention needed to complete the project within a single day, I welcome the developer’s proposal for the development cost.
