I think a mixture of both is quite necessary. Performing technical analysis is powerful as it really helps you understand how the trends are going but also intuition is important as the market does not always follow the predicted trend.
Most people are relying with other person's intuition which there's no specific may happen due to its unpredictable, for me I'm the one who make analysis and observation in order not to regrets at the time. Your the only one who make mistake.
