Post From: Renko Bar with Gap Fill None - still partly gap filling?

Hey Sierra team,

While working on an ASCIL study that uses renko bars I encountered some for me not reasonable behavior of your renko implementation.
It does not really make a big difference from a user perspective but since I couldn't really understand your implementation logic, I'd kindly ask you to shed some light in the dark, if possible.

When using a normal setup:
* Renko Bar
* New Trend Bar When Range Exceeded | New Bar When Open Crossed
* Gap Fill to None

I would expect that you don't fill a gap when the next tick last price is really "out of range" for the next brick. And while I found some examples where you do it, however, I found examples where you print bricks with almost artificial prices or even without volume.

I attached you some pictures with time and sales where you see the tick 19655.75 that results in two empty up bars - the first bar, not sure where you get the trade/volume from because according to time and sales there was none. The second bar it does not show any trade/volume. Lastly the tick price lands in the down bar with the wick. Interestingly this bar does not get the tick price as open but also an imho artificial one and again no trades/volume is shown - potentially you registered it to the first green up bar?!

The same occurs then with the down bars, because the price jumps again.

So apparently you are filling the gap. A few seconds later, see pic lastly_no_gap_fill.png there are no gap fills happening.

Could you please explain the logic to me or maybe even have the implementation open? And ofc, I've read https://www.sierrachart.com/index.php?page=doc/RenkoCharts.html#UsingNumbersBarsStudyOnRenkoCharts.

For the example pictures I used NQ 2024-09-19 at 2pm New York with 20 tick Renko Bar and 9:30 am session open
