Relative strength index is a classic technical indicator.
It is frequently applied to spot a market reversal.
RSI divergence is considered to be a quite reliable signal of a coming trend violation and change.
Though newbie traders think that the application of the divergence is quite complicated, in practice, you can easily identify it with the following tips:
💠First of all, let's start with the settings.
For the input, we will take 7/close.
For the levels, we will take 80/20.
Then about the preconditions:
1️⃣ Firstly, the market must trade in a trend ( bullish or bearish )
with a sequence of lower lows / lower highs ( bearish trend ) or higher highs / higher lows ( bullish trend ).
2️⃣ Secondly, RSI must reach the overbought/oversold condition (80/20 levels) with one of the higher highs/higher lows.
3️⃣ Thirdly, with a consequent market higher high / lower low, RSI must show the lower high / higher low instead.
➡️ Once all these conditions are met, you spotted RSI Divergence.
A strong counter-trend movement will be expected.
Also, I should say something about a time frame selection.
Personally, I prefer to apply it on a daily time frame, however, I know that scalpers apply divergence on intraday time frames as well.
❗️Remember, that it is preferable to trade the divergence in a combination with some price action pattern or some other reversal signal.
