I am trying to build a strategy with daily data, however, a run-time error showed "Sorry we do not have daily or hourly resolution yet. We recommend using minute data and building daily bars if required". Does this mean I have to use minute resolutions for all my tickers in my strategy in order to make it consistent? If so, how many minutes are included in a day? Is it regular trading hours only, or including pre-market, post-market hours or every minute in a day counts (24*60)?
