Nice idea on CADCHF and there may be bearish potential as you have identified. I have identified a resistance level at 0.77084, which is above your supply zone. It is a horizontal overlap resistance with 61.8% Fibonacci extension and 61.8% Fibonacci retracement. Stochastic is approaching its resistance at 99%, where a corresponding reversal could occur. If a reversal does occur, we may take a closer look at 0.75244. It is a horizontal overlap support with a 50% Fibonacci retracement. Looking forward to seeing how things develop.
Please have a look at my idea and share with me what you think.
