Great idea on GS. For our set up, we have identified major resistance and support levels. Price is approaching our first support at 171.75 which is made up of 61.8% Fibonacci extension , 76.4% Fibonacci retracement and a horizontal overlap support. We found a major resistance at 209.4, which is made up of 61.8% Fibonacci retracement and a horizontal pullback resistance. Stochastic is testing its support at 3.15% and we might see a corresponding rise in price should a bounce occur. Please take a look at our idea and let us know what you think.
