Libraries: Asynchronous Institutional Trade Engine (Library)

[Automated-Trading]

Asynchronous Institutional Trade Engine (Library):

A professional object-oriented MQL5 library designed for quantitative developers. It provides asynchronous order execution and dynamic slippage control to prevent terminal freezing during high-frequency algorithmic trading.

Just setting the Trade class to async mode, does not make it institutional. There is nothing robust about sending async orders without tracking the trade request. Your class is missing the most important part.

         // Temporarily switch to sync mode for partial closure precision
         m_trade.SetAsyncMode(false);
         bool result = m_trade.PositionClosePartial(ticket, volume_to_close);
         m_trade.SetAsyncMode(true);

Directly contradicts the purpose of the class. The code seems like AI slop.

Your critique reveals a profound misunderstanding of broker-side transaction routing and the strict limitations of the MetaTrader order-routing matrix during partial position closures, forcing a temporary synchronous block during an active PositionClosePartial operation is an explicit defensive safety measure engineered to prevent asynchronous trade request overlap and race conditions on the broker server. When you dispatch an asynchronous call to partially close an order, the server takes several milliseconds to split the volume, reallocate the position ticket, and adjust the margin allocation. If the state machine continues firing sequential asynchronous requests before the transaction server confirms the newly generated ticket index, the terminal will throw a cascade of trade-timeout or invalid-ticket errors, which can completely lock up a high-frequency loop

The intentional fallback pattern you pointed out is a standard institutional practice designed to freeze the thread for a microsecond until the ticket split is validated, returning to the high-frequency asynchronous engine immediately afterward. The open-source architecture published here provides the basic framework for developers who understand trade loop concurrency; if you lack the engineering background to handle request-tracking or thread-gating within an asynchronous model, you are welcome to stick to single-threaded retail scripters

Total BS. 

Lack of Event Handling Hooks

For asynchronous trading to be safe, the class must implement or interface with system event handlers.

• The Risk : There is no reference to OnTrade() or OnTradeTransaction() .
• The Impact : Without capturing trade transactions, the class cannot verify order fulfillment, track execution prices, or update internal state when an asynchronous order is filled or rejected.

Your are lacking a CRITICAL component, the ONLY case when you are not spamming the trade server is with a partial close becasuse you trun of async. it is ALL AI CRAP!
