Set what the trader's strategy tests report at every step: up to 8 items, each a field id from watch_fields or an expression over those fields (numbers, + - * / and brackets, optionally one comparison with < > <= >=). This replaces the list. It applies to the NEXT test, so offer to rehearse again afterwards. An item that cannot be read is refused by name and the rest are kept. Use it when the trader says what they want tracked ('watch the RSI and how far price is from the EMA'): translate their words into fields; never invent a field.
