i have simple query.. should gap up or gap down should be used as support or resistance i have attached a chart of bharti plzzz let me know how will gap works on this chart and how much volumes matters in gap up or gap down..... senior member plzz help ....
the bharti chart has a runaway gap which typically happens on low volume . In any case volume doesn't play a key role in runaway gaps.
Also its important to note that runaway gaps usually take a much longer time to be filled as it implies the presence of a very strong trend.
Breakaway gap is usually preceded by a classical break-out like ascending triangle , rounding bottom ,inverted h & s etc... the key point in a break-away gap is that if the volume is high before the gap then there are even chances that it will get filled even in a minor reaction and in that case the gap area may act as a support.
Find BHEL chart which shows a breakaway gap , between 2462-2503 area after a rounding bottom formation ,which got filled in the recent correction..
