MQL4 ERR_MARKET_CLOSED
MT4 error 132 market closed maps to ERR_MARKET_CLOSED: market is closed. The server will not accept the trade while the symbol is outside a tradable session. Capture GetLastError immediately after the failed call, correct the cause, and retry only when the condition can change.

}The official MQL4 runtime table names error 132 ERR_MARKET_CLOSED and defines it as “market is closed.” The server will not accept the trade while the symbol is outside a tradable session.
The error number is evidence about one failed call, not a diagnosis of the whole EA. Read the API sentinel first, then call GetLastError immediately because that function returns the current _LastError value and resets it.
Start with the inputs and external state that existed at the failure point. A later log entry or a successful call can overwrite the useful context.
Do not use rapid retries. Schedule the next check for a known open session and revalidate the current quote before submitting.
Keep the original trading and risk rules intact. A workaround that widens stops, increases volume, changes an account setting, or ignores a failed return value can hide the symptom while changing the system.
| Check | Action |
|---|---|
| The order is sent on a weekend, holiday, or session break | Record server time and wait for the next valid trading session. |
| The symbol uses broker-specific trading hours | Use the broker’s symbol schedule instead of a copied generic market schedule. |
| Tester session assumptions differ from the live broker schedule | Test session filters against live server time and the target symbol. |
| The EA retries a closed-market rejection as if it were transient network noise | Stop retrying until the session state changes. |
The diagnostic records the symbol and current quote when OrderSend fails. The EA still needs a broker-specific session filter because source code cannot reopen a closed market.
The example improves validation and logging. It does not prove the operation will be accepted by a broker or behave safely in live trading.

Open MQL4 Coding AgentStatic diagnostics do not prove runtime behavior, backtest results, broker compatibility, or live-trading safety.
Check the API return value before interpreting an error number from the log.
Call GetLastError immediately and record error 132, symbol, prices, volume, ticket, and terminal state relevant to the operation.
Record server time and wait for the next valid trading session.
Compile the revised source, then test with the same MT4 build, broker, symbol, account permissions, and market state.
ERR_MARKET_CLOSED means market is closed. The code should still identify which API returned failure and log the inputs used for that call.

Do not use rapid retries. Schedule the next check for a known open session and revalidate the current quote before submitting.
It reports the current _LastError value and resets it. Other operations can change the error state, so a delayed read may describe the wrong call.
Pineify can revise a self-contained .mq4 file, add validation and error logging, and return static MetaEditor diagnostics. It cannot prove broker acceptance, account permissions, market availability, or live execution.
