With the new Custom Sub Period on the TPO Study we can set the first 10 min bracket on the Notes. This is really cool but it still can mislead its reading. Looking at the image, on 7-17 we have the (m) period which is the 10 min bracket and then at 7:30 CT we initiated the (A) period. Looking at it it seems there's a 2 period bracket on that price area where indeed that was not the case, this can mislead the profile reading. So my idea would be to merge the first 10 min bracket with the (A) period. This would mean that the first bracket of the day would have 40 minutes instead of the standard 30 min but we would remove that (m) period and have a much better reading of the profile, without that 2 period bracket appearance. http://www.sierrachart.com/image.php?l=1374161035835.png Regards.

This is not completely clear for us and we do not have enough details, but we are doing some work in this area and going to have a new release out today or tomorrow and we will want you to do some testing and also review the release notes about the changes.

Hi, Maybe this can help explaining the problem. Market RTH open is 08:20. All settings are default. On the TPO we have a first "A" period from 08:20 to 08:30. A second "A" period from 08:30 to 09:00. B period from 09:00 to 09:30. C period from 09:30 to 10:00. We are supposed to have A period at 08:20, B at 08:50, C at 09:20 etc.. This also means the Initial balance is wrong because it shows 08:20 to 09:00 instead of 08:20 to 09:20. I have not succeed getting around this problem using the custom sub periods. But maybe I did something wrong. I am rather new to SC. W. |

"... We are supposed to have A period at 08:20, B at 08:50, C at 09:20 etc ... " Actually, no! TPO brackets are to be measure on each 30min period, A at 8:30, B at 9:00, C at 9:30, D at 10:00 and so forth... This is the standard (default) TPO settings. Everything outside this is your own way of reading it, not the way Market Profile was created. So for commodities and treasuries opening at 8:20, those initial 10 minutes need to be merged with the A period that starts at 8:30 otherwise we get the result already showed and explained here.

Hi trademechanics, OK and thank you. I merged the A periods and it worked. Now I wonder if the Initial balance is 08:20-09:00 or 08:20-09:30... will check what works best. W. |

Please see the release notes for version 998 here: http://www.sierrachart.com/index.php?l=doc/Whats_New.php Update to version 999 and see if this meets your requirements. Although as we read through how you want this to work, it does not seem so. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

This is not my topic, but the two sub periods resolved my problem. They are now set to 08:20-08:59 and 09:00-09:29. This gives me 40 and 30 mn first periods, a correct profile, and a 70 mn Initial Balance. However, I know some traders consider the Initial Balance to be 40 mn, so they will use 10 and 30 mn sub periods. The only remaining problem, for me, is that the value and POC computation is now different on the TPO Value Area Line. This is normal since it is impossible to set a different first periods like the TPO profile. I've posted a message about this : TPO Value Area Lines problem when first period is diffrent . W.

Please take a look at he following screenshot http://www.screencast.com/t/g6wVhzAt5zS4 First chart with the 10 min sub period is gives the (A) period for those 10 min and the (B) period for the following 30 min. But, using User24143 settings we can have indeed a 40 min initial bracket, by "merging" the initial 10 min with the following 30 min. The problem though it appears that sub period removes the (B) letter (not the period itself as I wrote on the chart). The period is there but with the letter (C). Although setting a sub period that extends the (A) period till 8:00, the study continues to distribute the letters the same way, on 30 min intervals. That's why we can't see the (B) letter. Due to the opening at 7:20 (sorry, i've always used exchange time so it's easier for me to mention Chicago time), even though we set the sub period, the study continues to read that initial 10 min as (A), the following 30 min as (B) and finally at 8:00 it initiates (C). The sub period should force the study to calculate the letter distribution differently. Yes, it continues to distribute the letter on 30 min intervals but always from that sub period onward. So if the sub period is between 7:20 and 7:59:59, which is the (A) period, at 8:00 the study should start the (B) period, not the (C). From there the distribution would run as usual, 8:30 (C), 9:00 (D), 9:30 (E) and so on... Of course theoretically it's easy to talk about this. If it's possible to code it, maintaining the integrity of all the other calculations that's another problem. Date Time Of Last Edit: 2013-07-24 08:16:26

trademechanic, I set the first AND second sub periods. So the B period does not disappear. I've attached a file to show that. |

Have you recalculated the chart ?
|

Yes, I recalculated and still no (B). It must have to do with the changes made on 998 and 999 versions. Will see what support have to say. |

To summarize: 1. You cannot use custom subperiods as you are with 999 and higher. They are going to conflict with the special 30 minute subperiod handling that exists. 2. As we understand, when you have a starting time which is not a multiple of 30 minutes or starts at 0:00, you want the very first subperiod to be more than 30 minutes and encompass this extra odd first time block. So for example with the session times that you give, the first subperiod will be 40 minutes. And then all of the subperiods after that will be 30 minutes. The letters will be applied appropriately. We can do this. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

I am not sure point 2 is right : * some traders want a first subperiod of 40 mn (like me, for a 70 mn IB). * other traders want a first subperiod of 10 mn. * and, yes, 2nd period, is always 30 mn. |

Exactly.If we cannot use the subperiods maybe it's better for you to remove them from the inputs so they don't confuse users? I believe it would be preferable to have a simple option so users can select if they want to merge the "odd" time block with the immediate 30 min block or not. If not than the periods will be plotted as they are now, the first 10 min bracket will be A, the immediate 30 min bracket will be B and so on. If users want to merge the "odd" period than the merged period will be A, the immediate 30 min bracket will be B and so on. This would be easier. Two options available, the only two possible, merge or not merge. Date Time Of Last Edit: 2013-07-25 09:37:55

We understand and we will add the option. This will be all done by the end of today. The custom subperiods are meant for another specialized purpose for a particular group of users. So those need to stay. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

This is now out in version 1000. Please let us know how it works. There is a new study input to support merging or not.

As far I can see, it's working perfectly. I'll continue to monitor it and if I find some inconsistency I'll report. Thanks |

I didn't know where to post this message since this is related to the TPO Value Area Study but since it's also related to the new merge option I decided to put it in here. Please see attached image. I'm overlaying on the TPO chart the TPO Value Area applied on the candle chart extending the previous day value area onto today's trading day. As you can see, there's a couple of value areas and POCs that are out of sync with the previous days value area on the TPO chart. Is it possible to fix this or since the calculations are based on a 30 min chart it's impossible to work with the "odd" open period? EDIT: Just been working with a couple of charts and different time frames and if I set the candlestick to a 10 min periodicity, the same as the "odd" open period the value areas become in sync with the TPO. Nice. Thank you Date Time Of Last Edit: 2013-07-27 16:29:19

Yes, I saw that thread. Maybe I should have posted it there... Anyway, like I said, the issue with the out of sync is resolved with a 10 min chart: |

if I set the candlestick to a 10 min periodicity, the same as the "odd" open period the value areas become in sync with the TPO. Yes this is essential. Otherwise, it is not possible to do accurate calculations. You can also use 1 minute and 5 minutes.

Can you confirm on your side with 30 minutes charts using the @ES#C IQFeed symbol? I'm seeing some out of sync days when I overlay the TPO Value Areas from a 30 minutes bar chart into the TPO chart. This should be in sync since we are dealing with 30 min periods. Thanks |
