Looking at thsi index in the major timeframes i coudl fidn a very nice set up forming on the weekly and daily tiemframe where price has been creating a typical break adn retest of a broken ascending TL and structure adn 3rd weekly impulse meaning a possible revesal and new downtrend formation so in order to confiorm this i have marked to critical rejections zones where price needs to clse below them on the daily timeframe to go down,first important area would be a clsoe below 23.300 giving a possible push to the 22.600 area and the other one woudl be a close below 22.250 and if a clsoe below the last mentioned area would mean a drop to the first and main parabolic TL (20.000)
