This one was hard, and there is not just one Gann possibility. I used the formula price^0.5*180 to convert the chart to degrees, and then normalize it by making the absolute bottom 0 degree and with the help of a factor of 10. The result seems correct, though, not certain. The most probable turning point for CADUSD in this picture is 120 degrees - 1/3. That level corresponds to the price 0.725. However, this does not mean the price will return from that point. This means, on the other hand: IF the price hits that level and returns in a strong manner, then it is very unlikely for it to revisit there again. So this is not a forecast, but just a confidence tool when the time comes.
