Distinguish the approaches

Manual trading relies on human interpretation. An EA usually executes predefined rules, while AI may support classification, forecasting or research. Hybrid systems are common, so an AI label says little about actual risk.

Test failure conditions

Test disconnections, repeated signals, missing quotes and rejected orders. A practice system might allow only one new order at a time and check for duplicates after reconnection. Correct execution does not establish profitability.

Keep human oversight

Define pause conditions, exposure limits and logs. Historical results do not replace simulation, and model explanations still require verification. Faster execution can also accelerate mistakes.

A controlled test

In an offline test, send the same signal three times. Check whether the system creates one order or three, and record why. This verifies duplicate-handling logic. Passing the test establishes that particular behaviour, not that the trading strategy will earn a return.
