If you don't understand the Fibonacci Retracement setup, excuse, I explain.
1- The retracement tool Is extended from the top of the candle that starts the previous decline with the 0.5 level at the candle pivot (lower price) of the price's retracement;
2- Then, the 0.786 (49467) level now Is the resistance for the pullback. Respecting that, the setup Is validated;
3- Now, the expected fall can be touch the levels below with a logical target at least the 0.236.
