Cannot market exit strategy, {strategy_id} not found

Error message

Cannot market exit strategy, {strategy_id} not found

What it means

Registration guard behind strategy_command_handler: market_exit_strategy needs a command handler for the strategy, but the strategy_id is not registered with the trader, so the exit-market command cannot be routed.
