Parameters from the server's own tool schema.
This tool modifies an existing algo order's parameters (take-profit/stop-loss prices or size). It is a reversible write operation on an existing order rather than executing a trade or moving funds directly, but it operates in a financial exchange context with high blast radius since incorrect TP/SL modifications could lead to significant unintended trading outcomes.
From the tool's definition Amend a pending spot algo order (modify TP/SL prices or size)
