Is there any indicator named gartley? If yes, then what is its use?

<p id="isPasted">The Gartley pattern is the most common harmonic chart pattern. Harmonic patterns operate on the premise that Fibonacci sequences can be used to build geometric structures, such as breakouts and retracements, in prices. The Fibonacci ratio is common in nature and has become a popular area of focus among technical analysts who use tools like Fibonacci retracements, extensions, fans, clusters, and time zones.</p><div style="box-sizing: border-box; position: relative;" id="isPasted"><div style="box-sizing: border-box; height: 461.6px; overflow: hidden; background: 0px 0px; position: relative; width: 600px; padding-bottom: 0px;" class="forexqa-img-container"><img width="5146" height="3959" data-sizes="750px" alt="Gartley Pattern" data-hi-res-src="https://www.investopedia.com/thmb/L7efxjIsczTNZMRlyWaiTSvM9Mo=/1500x0/filters:no_upscale():max_bytes(150000):strip_icc():format(webp)/GartleyPattern-5541ce000da34023a20348e5681bbffb.png" data-img-lightbox="true" sizes="750px" srcset="https://www.investopedia.com/thmb/MpbaEe8VGp6fpg3nM_RE5G0iUIc=/750x0/filters:no_upscale():max_bytes(150000):strip_icc():format(webp)/GartleyPattern-5541ce000da34023a20348e5681bbffb.png 750w" src="https://prod-forexqna.s3.amazonaws.com/uploads/froala_editor/images/1744095336727.png" style="box-sizing: border-box; height: auto; max-width: 100%; background-color: transparent; width: 730px; cursor: zoom-in;" class="fr-fic fr-dii fr-draggable forexqa-img"></div></div><p>Image by Julie Bang © Investopedia&nbsp;2020</p><p>The Gartley pattern above shows an uptrend from point 0 to point 1 with a price reversal at point 1. Using Fibonacci ratios, the retracement between point 0 and point 2 should be 61.8%. At point 2, the price reverses again toward point 3, which should be a 38.2% retracement from point 1. At point 3, the price reverses to point 4. At point 4, the pattern is complete and buy signals are generated with an upside target that matches point 3, point 1, and a 161.8% increase from point 1 as the final price target. Oftentimes, point 0 is used as a stop loss level for the overall trade. These Fibonacci levels do not need to be exact, but the closer they are, the more reliable the pattern.</p><p>The bearish version of the Gartley pattern is simply the inverse of the bullish pattern and predicts a bearish downtrend with several price targets when the pattern reaches completion by the fourth point.</p>
