The Slow Relative Strength Index by Vitali Apirine
The Tortoise Or The Hare
J. Welles Wilder’s classic relative strength index has enjoyed a large following of technical analysts over the years. Here’s a slow version of it.
The slow relative strength index (SRSI) is a momentum price oscillator that measures change in price movements relative to an exponential moving average (EMA). Like the relative strength index, it oscillates between zero and 100. SRSI is considered overbought when above 80 and oversold when below 20. SRSI can also generate signals by looking for divergences and centerline crossovers. Sounds similar to RSI, doesn’t it? It is, and in fact, I use Wilder’s RSI formula to calculate the SRSI.
