Get market quote for a symbol

Fetches the current bid price, ask price, and timestamp for a specific trading symbol. Note: Not all platforms support real-time quote fetching. If there is no response or an error is returned, it means the platform does not support this feature.

Set includeSymbolInfo=true to also receive the symbol details (points, digits, volume limits) in the same response, which avoids a second call to /accounts/{accountId}/symbols/{symbol}.
