Profitable Forex trading system and the Most important indicator in your chart 

Many traders, even those with experience use systems based on at least one of the Top five indicators which fall into one of two categories; Leading or Lagging: 
Moving Avarage - A Lagging indicator 
Stochastic - A Leading indicator 
MACD - A Lagging indicator 
RSI - A Leading indicator 
Bollinger Bands - A Lagging indicator 

Leading indicators are inappropriately named because none of them lead with any form of reliability. If this was not true then all traders would simply Buy an Oversold market and Sell it when it was Overbought, and vice versa. Systems based on Leading indicators do not work for one simple reason None of them lead with any form of reliability. 

Lagging indicators and systems based on them are ineffective because, as the name suggests They lag. 

The Forex Mean Reversion System is based on the Forex Mean Reversion Indicator It is neither a Leading or a Lagging indicator It is a real-time indicator that is based on a fundamental fact. 

It provides a true indication of when a market is Overbought/Oversold On ALL instruments across ALL time-frames.
