How to do an on-chart RSI modification?

<p id="isPasted"><a href="https://www.tradingview.com/script/9TpYIBZK-RSI-Modified/">RSI Modified</a></p><p id="isPasted">The RSI is an excellent indicator for determining when equities are overbought/oversold. Though I believe there is a shortcoming in using the 70/30 levels since they are static and do not adjust for when an equity is trending. It stands to reason that in a downtrend, the overbought might be less than 70 and the oversold less than 30—Vice versa for a bull trend. Using the built-in function of pivots, I have attempted to create overbought/oversold lines that adjust with the trend. Leaving the 70/30 lines on the indicator also helps visualize the equity trend. All pivot settings are adjustable in the input menu. The pivot limits serve as a filter for recording pivot points. For example, with an upper pivot limit of 60, only pivots greater than 60 will be recorded into the array used to determine overbought. The crosses represent which values are used to determine overbought/oversold and do not provide timely indications.</p><p><br></p>
