### Description

David Sepiashvili's Self-Adjusting RSI from February 2006 Traders' Tips (Stocks & Commodities magazine) presents a technique to adjust the traditional RSI overbought and oversold thresholds to ensure that 70-80% of RSI values lie between the two thresholds. Wealth-Lab's calculation is based on an algorithm by Sepiashvili which adjusts the thresholds based on a simple moving average of the RSI.

### Example

The demo Strategy below uses the traditional RSI rules, going long when the RSI indicator crosses over its lower benchmark and exiting when it crosses below the upper benchmark.

```using System; using System.Collections.Generic; using System.Text; using System.Drawing; using WealthLab; using WealthLab.Indicators; using TASCIndicators;namespace WealthLab.Strategies { public class MyStrategy : WealthScript { protected override void Execute() { RSI rsi = RSI.Series( Close,50 ); SARSIUpper saru = SARSIUpper.Series( Close,50,2.0 ); SARSILower sarl = SARSILower.Series( Close,50,2.0 ); ChartPane rsiPane = CreatePane( 40,true,true ); PlotSeries( rsiPane, rsi, Color.DarkBlue, LineStyle.Solid, 2 ); PlotSeriesFillBand( rsiPane, saru, sarl, Color.Silver, Color.Transparent, LineStyle.Solid, 2); for(int bar = GetTradingLoopStartBar(50 * 3); bar < Bars.Count; bar++) { if (IsLastPositionActive) { if( CrossUnder(bar, rsi, saru) ) SellAtMarket(bar+1, LastPosition); } else { if( CrossOver(bar, rsi, sarl) ) BuyAtMarket(bar+1); } } } } }```
