Nothing that I have said represents a shift in thinking. I have simply pointed out the limitations of data sets that do not have the same basis.
You can only compare results from tests that have the exact same data sets and rules. If a backtest can only access OHLC data, you cannot compare the results to live data unless the live strategy also only makes decisions based only on OHLC data. That means that if you want to peek into the intrabar historical data on a higher time frame, you have no choice but to use a datastream with a finer granularity. That is simply a function of how digital data is processed.
