Hi JonnyT,
The Deal4Free chart doesn't have a trippled bottom, nor does it have a double top breakout.
Strange - I did my own to check & I have both those features. The difference could simply be down to the base figure for the boxes. My boxes are based around 3600 (i.e. boxes at 3597, 3600, 3603, etc) and I was also using the mid-D4F price, so this would equate to boxes at 3595, 3598, 3601 with the bid price.
Using different box levels can result in quite different looking P&F charts (*). Indeed, when comparing different P&F charts it is probably sensible to ignore one box differences or where there is an extra column of minimum height. Actually, for direct comparison it is probably most sensible to use standard bar charts.
* - this is actually a bit of a philosophical issue which I have thought about for some time. If a P&F chart based on 3600, 3603, etc gives good signals but one based on 3601, 3604 doesn't then does that mean that the good chart is merely a statistical fluke? I have a medium term system for the Dow using a 50x2 P&F chart. It produces quite stunning results using boxes at 8000, 8050, etc. I have also checked it using boxes based on 10 & 60, 20 & 70, 30 & 80 and 40 & 90. With all of these the results are mediocre. This hasn't stopped me trading this system, but I do worry that the good results may revert to a mediocre mean.
