Problem is that your specification is not clear at all.
What we say here is not always going to be very thorough and 100% clear. The documentation is the best point of reference:
Renko Bar Charts


I had a look, it doesn't seem we can manipulate open/close/high/low can we ?
Yes you have complete control over this, start a post in that thread about the new interface and we will provide some examples for this.

Need more time on post #48. Will follow-up in a day or so.

1.
The documentation is the best point of reference:

This is the document that is not clear. Hard to check the logic of the implementation if the spec is fuzzy.
What we understand reading this document is that from the settings we will be able to define a trend amount and a reversal amount, this is OK.
Then the document states that if the price "travels" or "moves" these amounts, we create a new bar.
But it is unspecified how do me measure the price travel or move. Where is the start ?
It should be explicit that the start is the previous bar close. Or isn't it ?


2. Question : instead of having "New Reversal Bar When Reversal Amount Met"/"New Reversal Bar When Open Crossed(what does that mean)'????, could we have, like for the trend bars, a simple Amount Met/Amount Exceeded ? This would very likely restore the original functionality.

3. The "New Trend Bar When Exceeded" setting is not working (see chart)

We think you are looking at the wrong place on the Renko documentation page for the description. You need to refer to the Introduction section for the full technical description:
http://www.sierrachart.com/index.php?page=doc/RenkoCharts.html#Introduction

The other subsections, will as necessary describe alterations to the Introduction, like in the case of Flex Renko and Universal Renko or go into more detail where needed.

2. We still have to write up documentation for this. We will see about adding this.


We have looked at your screenshot, and we think the issue involves what is a completed Renko bar. Sierra Chart uses a definition of a completed Renko bar to mean where the open to close is equal to the bar size. The "Exceeded" mode does not alter this definition. And we very strongly question the validity of altering this definition in that case especially in relation to the standard Renko bars.

The concern at this point is not comparison to what was, or to another program, but what makes sense. The point of reference should always be to standard Renko bars, and what is considered a complete bar. If a complete bar is simply determined based upon the distance between the Open to Close, then that is what should be used consistently.

So rather than debating what is considered a "completed" Renko bar, we can just simply add new options to consider that the reference point for a reversal must always be the prior bar Close. And not the current bar when using "Exceeded" mode.

Not only for reversals, but for trends too. In exceeded mode, reference is the previous close.
We get a new trend bar as soon as the trend amount (Bar sized - Trend Offset) is exceeded.
We get a new reversal bar as soon as the reversal amount (2*Bar Size - Reversal offset) is exceeded.

We get a new trend bar as soon as the trend amount (Bar sized - Trend Offset) is exceeded.
Technically this does not make sense because as soon as the Bar Size has been met or exceeded, a new bar must be started, we cannot continue to accumulate volume and data on to the current bar.

yes in trend mode you accumulate until bar size is met, but the bar is not actually a real new trend bar until the level is exceeded. As soon as the level is exceeded the bar has its "new trend bar" status, it's drawn with it's virtual open/close, and we move on to the next bar.

OK it appears as though we now got what you are looking for in version 1641. At least we think so.

In the list of the New Trend Bar options for Renko bars, there are new ones to reference the prior bar close for reversals always. It is this change, which appears to have done it.

It looks perfect on the DAX!!! Better even then on NT where there were occasionnaly a glitch (white square on attached chart) !

Small issue on GDAXI though, where some candles have holes (second attachment).

Good to go on the CL Ninja UniRenko 262 aka Flex Renko 421x as well, except the same hole in the candle as seen on GDAXI (high volatility moment, gap fill=true). See the blue square.

In regards to the spot where the High-Low is not connected with the bar, actually must be correct because what happened on that bar with the gap is that there was an actual gap of price movement and that particular trade caused both a reversal and initiated a new bar. Since it initiated a new bar, it was added to the next bar. So the high low you see is correct.

We would not do anything to fill that.

The bar high represents the highest high and the low represents the lowest low of the actual trades contained within that chart bar.

No sure I'm getting it, ok here on the example the market dropped 12 ticks, but I'm in gap fill mode.
Why do we have a hole in the reversal candle on that move down ?

If we have a 12 tick gap in the trend direction, we get 12 nice up bars. Why a hole if we get a 12 tick down move ?

There are no holes/gaps in regards to the Renko bars themselves. Those are always filled in.

We tried to explain this as best as we could previously. We cannot spend more time on this. It does make complete sense. We made a slight addition to our prior response.

This discussion must come to an end. We are not going to say anything further. In the end, if these bars do not meet your requirements, then make your own. Also you would see less of that situation if you do not use this new mode we added. This new mode makes no technical sense to us.

It's OK don't touch the bars. But please at least explain why, when the market gaps down from 52.38 to 52.26 in 1 tick, we get a series of Renko candles with a gap between 52.34 and 52.36 ? ( see my previous hole.png chart).

Why 52.34 and 52.36 ? Nothing happened at those prices, market just went, on 1 tick, from 52.38 to 52.26

(october 17 , CL close)

Of course there is a logic, you're just too obsessed by proving them wrong that you're not trying to understand it.
What we have determined, is that aside from the nonzero Flex Renko offsets for trend and reversal bars, the NT Universal Renko bars, do not follow standard Renko logic in regards to points of reference and the starting of a new bar.

What you end up with is a high to low range at some points of reversals where there could be a complete Renko box shown, but there is simply is not.

Refer to:
http://www.sierrachart.com/image.php?Image=1511137149129.png

Now any average average user will look at that and say why is there not a box there. There should be.

With the 9 different Renko New Bar Mode options, Sierra Chart gives you the full flexibility to accomplish what any user wants now. One methodology simply is not correct. That is clear. What you can see in the Sierra Chart image above, is that the logic you have described, now can be applied even standard Renko bars.


The Ninja indicator and the previous Flex Renko implementation use the virtual Renko open = previous bar close. So they measure everything starting from there.
Once you get that, everything just makes sense. I attach a chart describing very clearly how it works. It is perfectly logic.
It was not this simple but we finally got it in 1647. The more recent changes before this, still were not correct.

Post #64 will have to be explained another time. We cannot spend time on that now, but it is all correct.
