Universal Renko bar fill on new bar creation

Support Request:

Attached is a snippet comparing the NinjaTrader 2-2-6 vs the Sierra Charts 4-2-6 Universal Renko bar chart bars. In particular, note the last bar. On NinjaTrader, a new bar is filled from the offset position immediately when the bar forms. On Sierra Charts, the bar doesn’t fill from the offset until the bar closes. The offset position is the middle of the previous bar for these settings.

Also attached is a snip of my Sierra Charts chart settings.

1. Is there a way to configure the Sierra Charts 4-2-6 Universal Renko bar chart to immediately fill from the offset position when the bar forms?

2. if the answer to 1. is "no", is it possible for a code-savvy user to modify the existing Universal Renko chart code to make their own Uni-Renko chart code? Is the existing Universal Renko chart code available?

3. If it is possible to create custom chart code, have any users already done this and posted it somewhere? Where would I check for this?

FYI- I already read the whole page on Renko charts: https://www.sierrachart.com/index.php?page=doc/RenkoCharts.html so no need to redirect me there.

Thanks in advance.

1. No this is not supported.

2. Not now. The code is not available and would not be useful in the way that it exists.

3. This capability does not exist but will be available in 45 to 60 days.

Also Universal Renko bars are currently undocumented.

I'm also very interested in this capability. Any update on the status?
Thank you.

We are doing our best to get this done. Hopefully this week maybe.

But unfortunately we get very bothered on this support board which is a major distraction.

Just checked the universal Renko chart operation for the latest version of code, AT1633 (I had also tried AT1628 last week and saw similar results). I can't seem to find any universal Renko settings that provide the desired operation I'm looking for. I reverted back to the AT1614 code and the operation was much closer to what I desire. I captured some snips of the desired operation vs the SC universal Renko chart operation and summarized this in the attached doc. I also tried to describe the desired operation in more detail after the snips. Please review and comment.

Thanks in advance.

We are still looking over your document but there is no need for all these details, at least we do not think so. There was a problem where the reversals were just not handled right on Flex Renko and Universal Renko in the last couple of versions. The offset just was not being applied.

This will be fixed with a new version out tomorrow.

Refer to the version notes for 1646 and use that version. We did some additional Renko development:

Let us know when you have had a chance to test the latest prerelease version because we do think it should do exactly what you require if you use this Renko Mode setting:
New Trend Bar When Range Exceeded | New Reversal Bar When Reversal Amount Met Plus 1 Tick and References Prior Close

I checked the new pre-release, AT1647, yesterday and today, though today is a bad day to compare due to lack of choppiness (in the chop and at reversals are where the differences are most obvious). I tried the 4-2-5, 4-2-6, and 4-2-7 settings for the Flex Renko Inverse bars and I tried all New Trend Bar... settings for each. I was unable to find a good match to the desired renko bars.

Yesterday, I also reverted back to the AT1614 release and compared the 4-2-6 universal renko bars to the desired bars. The match was quite good except for 2 bars at the end of a bull run (see attached). The AT1614 4-2-6 renko is the closest match I've found so far, but it's not perfect as shown in the attachment.

On the desired chart, the topping green bar body high at the top of the run would never be greater than the wick or body of a following red bar because in order for the next bar to form following the green topping bar, a price 1 tick higher than the body high of the green topping bar would have to occur, and this price would show up as a wick that is higher than the green topping bar body on a following red bar (as shown on the desired chart).
We do not agree with the statement because the price action could cause this condition, but this is not relevant because you are comparing to 1614 which we no longer support and there may very well have been a problem.

However, as you can see in the current implementation which is a much more thorough and complete implementation which was one of the objectives of the recent work on Renko bars, you do not see what you are describing:
http://www.sierrachart.com/image.php?Image=1511304411475.png

So you can see how this issue was resolved.

Aside from this, the way that we ask that you look at this, is to read over the specifications here:
https://www.sierrachart.com/index.php?page=doc/RenkoCharts.html

And decide what particular Renko New Bar mode that you want to use:
https://www.sierrachart.com/index.php?page=doc/RenkoCharts.html#RenkoNewBarMode

And surely you must find one that you would find sensible in your own mind.

Decide on the Bar Size, New trend bar amount, and reversal amount.

And then look at the underlying tick by tick data, and validate that what Sierra Chart provides is 100% accurate and perfect. All of this is of the highest technical standard. There is not even a document out there which even explains Universal Renko bars, unlike the thorough documentation we provide for Renko bars in Sierra Chart.

It should not be a matter of trying to match a substandard and improper chart in the other program despite the following it may have. We have proven that it is just not accurate, in at least one way where it does not catch all reversals, and does not follow proper Renko bar construction methods.

What we offer is unquestionably 100% technically accurate and done properly to well-defined and proper specifications. This is what we hope you will see, and the others apparently you are working with in your trading room.

There simply is not anything further we can or willing to do.

The 4-2-2 Flex Renko with the 3rd New Trend Bar setting matches very well - after I adjusted my Start Time. I originally saw a glitch where one of the bar bodies was only 3 ticks instead of 4. I looked into this and discovered the glitch tracked the Start Time. I had assumed that selecting "Use Evening Session" and setting the Evening Start and Evening End Times overrode the other Start and End Times in the Session Time section, but it doesn't. This may have been one of my issues all along. Anyway, it looks like the 4-2-2 setting is working. I'll monitor it for a few days and see how it goes.

Thanks in advance.
