[blackcat] L3 Supertrend of Nadaraya-Watson Envelope

The Nadaraya-Watson Envelope is a statistical technique used in finance and time series analysis. It is derived from the Nadaraya-Watson estimator, which is a non-parametric regression method.

In the context of the tradingview pine script provided, the Nadaraya-Watson Envelope is calculated based on the Volume Weighted Exponential Moving Average (VWEMA). The VWEMA is a type of moving average that takes into account both the price and volume of an asset. It is calculated by multiplying the closing price of the asset by its volume, then applying an exponential moving average to the result. This weighted moving average gives more importance to periods with higher trading volume.

The Nadaraya-Watson Envelope consists of an upper and lower envelope, which are calculated by applying a smoothing factor (alpha) to the standard deviation of the VWEMA. The standard deviation measures the volatility of the VWEMA, and the smoothing factor determines the width of the envelope. By adjusting the smoothing factor, traders can customize the sensitivity of the envelope to market conditions.

The Nadaraya-Watson Envelope can be used to identify potential overbought and oversold conditions in the market. When the price of an asset moves close to or beyond the upper envelope, it may indicate that the asset is overbought and due for a price correction. Conversely, when the price moves close to or below the lower envelope, it may indicate that the asset is oversold and due for a price rebound. Traders can use these signals to make informed decisions about buying or selling assets.

Additionally, the Nadaraya-Watson Envelope can be used to generate trading signals. For example, when the price crosses above the upper envelope, it may indicate a buy signal, suggesting that the price will continue to rise. Conversely, when the price crosses below the lower envelope, it may indicate a sell signal, suggesting that the price will continue to decline. Traders can use these signals in conjunction with other technical indicators and analysis to make well-informed trading decisions.

In summary, the Nadaraya-Watson Envelope is a powerful tool in technical analysis that combines the Volume Weighted Exponential Moving Average with upper and lower envelopes. It helps traders identify potential overbought and oversold conditions in the market and generate trading signals. By incorporating this technique into their analysis, traders can gain valuable insights into market dynamics and improve their trading strategies.
