Using theĀ Bar Hour building block you get strategies such as:
LongEntrySignal = (((Bar Hour[5] < 18.0)
and Open below BollingerBands(Main chart,10, 1.9).LowerBand)
and (Bar Hour[3] crosses above Bar Hour[4]));
ShortEntrySignal = (((Bar Hour[5] > 18)
and Open above BollingerBands(Main chart,10, 1.9).UpperBand)
and (Bar Hour[3] crosses below Bar Hour[4]));
What does Bar Hour crosses above and crosses below, surely there is no such concept?
