Discuss Sofia's answer to: Is there any intelligence to trading FOREX or is it merely subject to interbank flows and basic supp/demand?

There is definitely a science of cause and effect and logical trends and patterns in the Forex market.

Technical analysis is a sound strategy in trading Forex and here is why...

The large money management firms, the hedge funds and the sovereign wealth funds all use programmatic systems to monitor and signal entries and exits in the Forex Market . If an individual trader studies technical analysis they can use the same pivot points, Fibonacci theory, support and resistance levels that the big boys use.

This gives you enough edge in trading Forex that you can increase your probability of success.
