What the CIEN RSI tells you
The Relative Strength Index (RSI) measures the speed and size of recent price moves on a scale from 0 to 100. It is one of the most widely used momentum indicators in stock trading.
A reading at or below 30 is considered oversold: selling may be overextended and a bounce more likely. A reading at or above 70 is overbought: buying may be stretched and a pullback more likely. Between 30 and 70 is neutral. Signals are strongest when several timeframes agree, which is why the table above shows Ciena on all of them at once.
RSI is a guide, not a guarantee. A stock can stay oversold or overbought for a long time in a strong trend. Traders usually combine it with divergences, volume and structure, all of which you can check on the live chart.
