Lanczos CandlesThis indicator reconstructs price action using Lanczos resampling, incorporating lower timeframe data to create a more detailed representation of market movements. Traditional candle aggregation on higher timeframes tends to lose some price action detail - this indicator attempts to preserve more of that information through mathematical resampling.
The indicator samples price data from a lower timeframe and uses the Lanczos algorithm, a mathematical method commonly used in signal processing and image resampling, to reconstruct the price series at the chart's timeframe. The process helps maintain price movements that might otherwise be smoothed out in regular candle aggregation.
The main settings allow you to select the source timeframe for sampling, adjust the Lanczos filter width to balance smoothness versus detail preservation, and optionally enable Heikin Ashi calculation. The filter width parameter (default: 3) affects how aggressive the smoothing is - higher values produce smoother results while lower values retain more of the original variation.
This approach can be useful for technical analysis when you want to work with higher timeframes while maintaining awareness of significant price movements that occurred within those candles. The optional Heikin Ashi mode can help visualize trends in the resampled data.
The indicator works best when there's a clear ratio between your chart timeframe and the source timeframe (for example, using 1-minute data to build 5-minute candles).

Renko MTF - Traditional and ATRSomehow there aren't too many renko bars that have the traditional setting built-in so I put one up. This one has the option to choose between Traditional and ATR, the size number corresponds to the option that was chosen. And just in case if anyone wanted, I put up a multi-time frame option to choose the time frame the bars take place. D is for day, W is for week, flat numbers are in minutes, and leaving it blank looks at the current time frame the chart is in. The calculation comes from how Tradingview handles renko bars.
Renko bars don't paint a color unless the market moves a certain amount based on its settings. When the market moves up it turns green, if it moves down it turns red, simple color changes alone can say a lot. They're a good way to try to find trends somewhat objectively and seem to be a good way to eliminate time and can replace other time-based indicators that can whipsaw or lag. The bars have a tendency to repeat themselves so it's a good way to find trends. There aren't too many settings for the box size, most people either just choose 5, 10, 14, etc where as other indicators have many options that differ on different markets. The numbers can be chosen easily enough to pick a sweet spot with just a single input where other indicators such as MACD have multiple inputs to pick the right number that can make it difficult to choose from(although it won't be as precise as a MACD would sometimes but can be worth the objectiveness and consistency and same setting repeatability in different markets in my opinion). Some example strategies could be to use them as an alternative trailing stop, finding trends, a simple color change for entry and exit on top of other strategies, etc. It can do the job of many in an all in one price action type indicator(although not better all the time, it can come close enough). Despite all this, it does seem to depend on which time-frame it's being looked at, how TV does the calculation for it, and how one can use this with the lack of practical information on it out there.
