Hi, The smaller chart shows a two box reversal even though it's configured for three, like the other chart (both charts have identical settings). I already tried to Delete and Download Data. How can I fix this? Thanks. http://www.sierrachart.com/image.php?Image=1536785984959.png |

Here is the documentation for how Point and Figure bars are constructed: Point and Figure Chart The Reversal Size does not mean that there is always going to be a minimum of three boxes before a new column is started. Otherwise, there can be conditions where a new column never starts. If the price of the symbol reverses direction by the number of boxes specified by the Reversal Size Input setting or more, then a new column is created in the opposite direction. If the prior column consisted of X's, then the next column will be O's, or O's if the prior column is X's.

There are actually two issues here. 1) "The Reversal Size does not mean that there is always going to be a minimum of three boxes before a new column is started". Sorry but this doesn't make any sense and it's contradicted by what's in your link: "If the price of the symbol reverses direction by the number of boxes specified by the Reversal Size Input setting or more, then a new column is created in the opposite direction." If the reversal size is set to "3 boxes" then you simply can't have a "2 box" reversal. Incidentally I only see this on my CL (Crude oil futures) and GBP (British pound futures) charts -- not on ES, YM, NQ, RT, EUR, or JPY. 2) My screenshot shows two charts with the same settings yet different bars. How is that possible? This is a consistent problem on the CL charts, and practically non-existent on the others. Thanks! |

If the reversal size is set to "3 boxes" then you simply can't have a "2 box" reversal. We are looking at one particular example, and we will explain how the reversal is calculated. There is a down bar with a low of 69.80. The price moves to 69.90. If you count boxes there is a box at .8, .85 and .9. This is a total of three boxes and is a reversal. So it looks right to us.You can also create your own bars: ACSIL Interface - Custom Chart Bars 2) My screenshot shows two charts with the same settings yet different bars. How is that possible?

We say it looks right to us, but really the way it works is based on prior questions from users where when counting boxes, there is a reversal by the number of boxes counting from the low/high of the current bar. We think that it probably did not work this way previously but was changed based on a prior question. It would seem to make sense that there would have to be price movement in this particular example to 69.95. But then there would be a total of four boxes counting from the low of 69.80.

Yes price has to hit 69.95 to reverse into Xs, this is how P&F charts should work. If you count the bottom of the O at 69.80 then yes, it's four boxes above when the first X column is drawn. This is the definition of a "three box reversal" and I think the Point and Figure study gets it right. I only encountered this issue recently when I switched my intraday charts to the new Bar Period Type.

Okay what we found is that actually it is implemented to calculate the reversal properly so that the difference in prices has to equal or exceed the reversal amount. And the only places we could find where there were two boxes is where there was the start of a new trading day. Make sure this option is disabled: Chart Settings: New Bar at Session Start (Chart >> Chart Settings >> Session Times >> Intraday Chart Session Times menu) Sierra Chart Support - Engineering Level Your definitive source for support.

Here is a screenshot of many two box reversals from the past few days on CL. I've noted the dates and times that were displayed by the cross-hairs for each instance. http://www.sierrachart.com/image.php?Image=1537147602423.png I've always had New Bar at Session Start disabled and these reversals definitely do not occur at the start of a trading day. For comparison, looking at the same time period on a chart with the Point and Figure study (with identical chart settings) does not cause two box reversals. For reference my session times are: Start Time 06:00:00 End Time 13:59:59 [x] Use Evening Session Evening Start 15:00:00 Evening End Time 05:59:59 |

We cannot reproduce the issue. We definitely need to get that particular chart by following the instructions here: Support Board Posting Information: Providing Chartbook with Only a Single Chart We do not need an image. We need the Chartbook. Also, set Sierra Chart to a Tick by Tick Data Configuration.

Okay we have so far narrowed the issue down to just simply a case where there is a missing Box like an X or O. Otherwise, the chart bar formations are correct and the reversals are correct.

The problem relates to the accumulation of floating-point error over a large span of bars.
