Exponential SAR based MA

**Description:**

The "Exponential SAR" (ESAR) indicator is a modified version of the classic Parabolic SAR (Stop and Reverse) indicator, incorporating an exponential moving average (EMA) smoothing technique. It aims to provide traders with a smoother representation of trend changes in the price action of a financial instrument.

**Functionality:**

The indicator calculates the Parabolic SAR values using specified parameters for start, increment, and maximum values. These parameters control the acceleration factor of the SAR. The calculated SAR values are then smoothed using an exponential moving average with a user-defined length, providing a more refined interpretation of trend dynamics.

**Inputs:**

- **Length:** Specifies the length of the exponential moving average used to smooth the Parabolic SAR values.
- **Alpha:** Defines the smoothing factor for the exponential moving average, allowing users to adjust the level of smoothing applied to the SAR.
- **Start, Increment, Maximum:** Parameters controlling the acceleration factor of the Parabolic SAR.

**Usage:**

- **Trend Identification:** Traders can use the Exponential SAR to identify trend reversals and continuations in the price action of a security. Bullish signals occur when the price moves above the ESAR, indicating an upward trend, while bearish signals occur when the price moves below the ESAR, signaling a downtrend.
- **Trend Confirmation:** The smoothed nature of the ESAR helps traders confirm trend changes more reliably, reducing the impact of false signals commonly associated with the standard Parabolic SAR.
- **Risk Management:** By incorporating a smoothed SAR, traders can make more informed decisions regarding entry and exit points, improving risk management strategies.

**Customization:**

Users can customize the indicator by adjusting the input parameters according to their trading preferences and market conditions. Experimenting with different lengths and alpha values can provide insights into the effectiveness of the ESAR in various trading scenarios.

**Note:**

As with any technical indicator, the Exponential SAR should be used in conjunction with other analytical tools and risk management techniques to validate signals and mitigate potential losses. Additionally, traders should consider market conditions and adapt their strategies accordingly.
