if you're considering selling USD/CHF (the US Dollar against the Swiss Franc) due to an ABC correction wave, it suggests that you believe the market has completed the A and B waves, and you expect a strong downward movement (C-wave) to follow. This would mean you're anticipating a further decline in the USD/CHF exchange rate.
However, trading decisions should be based on thorough analysis that includes not only technical patterns like the ABC correction but also fundamental factors, market sentiment, and risk management strategies. It's also important to note that forex trading involves substantial risk, and it's always a good practice to consult with a financial advisor or do your own research before making any trading decisions. If you're not an experienced trader, it might be wise to practice caution and consider gaining more knowledge before entering the market.
