¿Qué es RSI?
RSI measures impulso - is a acción overbought (too high, due for drop) or oversold (too low, due for bounce)? Ranges from 0-100. Above 70 = overbought. Below 30 = oversold.
Piénsalo así
Piensa en a rubber band. Stretch it too far (RSI > 70) and it wants to snap back. Let it go slack (RSI < 30) and it wants to tighten. RSI measures how stretched the precio is.
