The LinRegExtreme-FIN[SS] Trend Algorithm uses advanced regression and standard deviation calculations to create a visual filter on the price chart of an investment instrument, distinguishing between upward and downward movement waves. The FIN[SS] Algorithm also enables informed buy-sell and partial profit-taking transactions. At the beginning of an uptrend, it generates a BUY signal when the price threshold for a trend or wave formation is crossed, and a SELL signal when the uptrend or trend is complete. A detailed explanation of the algorithm's operating dynamics, signal criteria, and sample applications are included in the training content. I wish you success.
