[blackcat] L1 Python Friendly Lucid SAR

2022年6月9日

Level 1

Background

LUCID SAR is an interesting technical indicator. I'm having trouble converting this to Python code. So a "Python friendly" version was rewritten literally. Because some basic functions and structures have been replaced. The performance can be 100% consistent with LUCID SAR.

Function

Mr. Bowman wrote this script after having listened to Hyperwave with Sawcruhteez and Tyler Jenks of Lucid Mr. Bowmannvestments Strategies LLC on July 3, 2019. They felt that the existing built-in Parabolic SAR indicator was not doing its calculations properly, and they hoped that someone might help them correct this. So Mr. Bowman tried his hand at it,adding the rule regarding the SAR not advancing beyond the high (low) of the prior two candles during an uptrend (downtrend), but the core script is as it was.

I use large sized cross with red color for downtrend, with green color for uptrend, so that when I overlapped original work from Mr. Bowman, they can be 100% matched, which provided a validation process for this re-writing work. Enjoy!

Remarks

Feedbacks are appreciated.
Python version Lucid SAR performance discussion is desired.

OVERVIEW
The [blackcat] L1 Python Friendly Lucid SAR is an enhanced version of the traditional Stop-and-Reverse (SAR) indicator designed to be more intuitive and user-friendly. This script calculates the SAR values using a custom algorithm inspired by Python's lucidity, providing traders with clear buy and sell signals based on price action. The indicator plots these points directly on the chart, making it easy to visualize potential trend reversals 📉↗️.

FEATURES

Calculates Stop-and-Reverse (SAR) points using a custom algorithm:
Initial Acceleration Factor (AF_initial): Starting value for acceleration factor.
Increment: Value added to the acceleration factor after each new extreme point.
Maximum Acceleration Factor (AF_maximum): Maximum allowed value for the acceleration factor.
Plots SAR points on the chart with distinct colors:
Green dots indicate bullish trends.
Red dots indicate bearish trends.
Provides clear visual cues for trend changes and potential reversal points 🎯
HOW TO USE

Add the indicator to your TradingView chart by selecting it from the indicators list.
Adjust the AF_initial, AF_increment, and AF_maximum parameters as needed to fine-tune the sensitivity of the indicator ⚙️.
Observe the plotted SAR points on the chart to identify potential trend reversals.
Use the green and red dots as signals for buying and selling, respectively.
LIMITATIONS

The indicator may generate false signals in highly volatile or ranging markets 🌪️.
Users should combine this indicator with other forms of analysis for more reliable trading decisions.
The effectiveness of the indicator may vary depending on the asset and timeframe being analyzed.
NOTES

Ensure that you have sufficient historical data available for accurate calculations.
Test the indicator thoroughly on demo accounts before applying it to live trading 🔍.
Customize the appearance and parameters as needed to fit your trading strategy.
