after a breakout how much fall below the support line is considered as false breakout?
does volume come into consideration when we try to determine false breakout?
The price dropping and remaining below the support line itself is considered a false breakout. There is no "how much below". It may even go down to the next support line. Also volume is not a consideration, the drop may be on small volumes.( I have noticed that normally volume decreases)
I am enclosing the chart of Alok Textile showing a false breakout in September 2004. Please note that it is not an ideal example. But this is the only one I could get hold of now. It does present some idea of a false breakout.
Normally in a break out after the penetration of the resistance line, the traders are reluctant to accept the new higher price level and there will be selling pressure. The price will then return to earlier resistance / present support level. This is called the
TRADERS REMORSE. The action of the price after the Traders Remorse is very crucial. The price may rise to higher level from the support line signaling the breakout. If the general feeling is still that the new price is not warranted then selling persists and price goes down further. This results in a Bull trap (refer Saint's post) or False breakouts.
Iam enclosing the Chart of Alok Textile showing the recent breakout. The Traders Remorse is quite visible in this.
Thus it may be a better idea to enter the stock after the upturn from the pullback (trader remorse ). see chart.
Hope I was able to clarify your doubt.
