In the world of foreign exchange (FX), two indicators help traders decode market mood: Risk Reversal (RR) and Butterfly (BF) volatilities. Imagine RR as a compass, pointing to bullish or bearish winds by comparing the price expectations of currency going up (call options) to it going down (put options). On the other hand, BF is like a barometer, forecasting calm or stormy weather by measuring the expected price stability of currencies.
Les risk reversals (RR) et les volatilités butterfly (BF) offrent des indications clés sur le sentiment du marché FX. Le RR mesure la différence de volatilité implicite entre calls et puts, reflétant un biais haussier ou baissier. La BF quantifie les attentes de volatilité autour du niveau ATM, révélant des périodes d’incertitude ou de mouvements de prix.
