This error occurs when there are no available prices for the selected instrument at that moment or when the last recorded prices are no longer valid. When a trader attempts to execute an order at these outdated prices, the trading server returns an "Off Quotes" message and denies the execution.
Other possible causes include:
The instrument being traded is no longer available.
A previous trade rejection, such as "Not Enough Free Margin."
To troubleshoot this issue:
Avoid trading when the market is highly volatile and liquidity is low.
Verify that the instrument is available for trading.
Review preceding rejection messages in the log or journal to identify any other errors affecting trade execution.
