This is a WMA equipped with a feature that allows you to adjust when to start real-time drawing, anywhere from 0 seconds to 5 minutes before the candle closes. It also includes other useful features.
[WMA]
The WMA (Weighted Moving Average) is a moving average that places the greatest weight on the most recent price data, and decreases that weight at a constant rate as it goes further back in time. Because the EMA decays past data "exponentially," even data from 10 years ago continues to leave a microscopic impact on the calculation indefinitely. On the other hand, the WMA has the characteristic of "completely excluding" old data that falls outside the specified period from the calculation.
