george - I don't see this either. In fact, at the risk of generalising, the dramatic market moves tend to be reversals, and these need to emerge from a trend, hopefully with a reversal signal, which also needs to occur at the end of a trend. But a range is not a trend, so don't expect a signal. Even though candlesticks give 4 significant price levels, OHLC, and their use gives more weight to the O-C 'real body' element, the close is always the most significant price of any session.
