Hi, Babu,
One qn about trendlines, just to get an opinion... is a trendline valid once its breached ?
Just want to know what eveyone feels on the issue, i think emperically and logically i have the answer but whats your point of view ?
[Please keep in mind the answers to "What exactly is a trendline?" and "What validates a trendline?" when answering the above]
Thanks.
Is a trend line valid, once it is breached?

One must have a dynamic view as far as Technical Analysis is concerned. How this dynamism plays an important role is explained below.
Once a trend line is breached, there are three possibilities.
1. A reversal or
2. A side ways movement or
3. The continuation of the same trend but to a much shallower degree than the previously steeper one.
Case Study of Bank Nifty on Daily chart
Period: Jan ’08 to Apr ’09 down trend period
Chart legends:
Line 1B: The very obvious down trend line of that decline.
Line 1A: Drawn connecting the points 1 and 2 (Lower High of May ’08).
Line XY: it isn’t a trend line but a Support during Oct & Nov ’08 and Jan & Mar ’09.
Let’s consider the down trend line 1A (hmm.. sounds like a bus route, here in Chennai). It had consistently been Resistance level at points marked 2, 3 and 4. After the point 4 Resistance, there was a break out in Aug ’08. Let’s pause here for a while. Since, there was a break out, did it stop us from extending that line? Not at all! As an analyst, we would always extend these trend lines to see whether there would be any retest to happen in future; if so, will these extensions provide the required Support (in this case) or Resistance (in case of an uptrend line break down). Here, there was a retest at point 5 which held well as a Support. Again, this extension of the down trend line held up as Support levels at points 6 and 7.
One may question about the validity of this Support level when the price went down through this line twice, between the point 6 and 7. I’ve drawn the Support line XY at lows of those pull backs which later had provided Support on two other occasions. Please be reminded that the line XY is not a trend line but a Support level formed when price went down through our main trend line 1A. The reversal occurred from the point 7 and to dwelve upon it would be a deviation from our point of discussion now.
The down trend line 1A was breached in Aug ’08; the trend still continued but on a slightly shallower angle; and the price happened to take the Support of this breached down trend line before reversing at point 7 for good.
Conclusion:
The trend lines must dynamically be extended, even if breached, to get a clear picture of the price actions.
