The prices
The reading
The 14-period RSI is 37.1: between 30 and 70, so neither side has dominated recently.
- Simple 20-period average
- 100.24: the last close of 96.14 is 4.09% below it.
- Exponential 20-period average
- 100.02: the last close of 96.14 is 3.88% below it.
- Read it with care
- In a strong trend the RSI can stay above 70 or below 30 for weeks. On its own it is a description of the recent past, not a signal.
Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

What the RSI measures
The relative strength index compares the average rise with the average fall over the last 14 closes, smoothed the way J. Welles Wilder set out in 1978, and scales it from 0 to 100. Above 70 is called overbought, below 30 oversold. It tells you how one-sided the recent moves were, nothing more.
Simple rules such as buying at 30 and selling at 70 often fail once costs are counted, and in a strong trend they sell far too early. If you use it, test the exact rule on your market first. See the trend filter lesson for what a moving average did over a century, and the historical volatility calculator for the size of the swings.
