"I noticed that gold (spot and August) seems to have left a gap of approx. 4 dollars on the 5 minute chart at about 1 p.m. on Friday, when it finally broke 1250. Do you think this is of any practical significance? I.e. are such gaps likely to be filled in your experience, or could gold continue on up without ever filling it - or at least not for weeks/months/years? Your take on this would be much appreciated."

David Fuller's view Most price gaps occur in thin markets, or after news that changes sentiment, or during breakouts which trigger stops and other limit orders. Although a gap can be part of a price dynamic, statistically, most will be filled, sooner or later, because markets fluctuate.
