Trading a system does not involve two hours (or two minutes) of "research" per day.
Trading a system does require acquiring daily data (price data, fundamentals data, sentiment data, astrological data, etc.), running software, preparing order sheets, checking orders, filing records, reconciling statements, documenting filled orders, tracking slippage, placing new orders, canceling obsolete GTC orders, moving stops, correcting out-trades, and balancing accounts. This may require a substantial amount of time. But none of it is "research".
