I cannot tell because all the trading techniques have different result due to the market volatility. If you are knowledgeable enough, I think you can increase your income out of it or have a consistent earnings.

Well, maybe it improves your daily income or in the contrary it gives you headache. All I can say for the beginners, they must use simple trading techniques and avoid complicated methods.

Using different techniques has no guarantee in making profits. Your profits defends how you manage your trades and analyze the current news.

You will be confused for sure. Mixing trading technique is not a wise moves according to Forex experts. Every pair has different movements, so other methods are not applicable.
