This method works in all sessions. We have found its performance to be strongest in the London, then the U.S., and lastly, the Asian, but it is effective in all sessions, and you will find traders in the PIP SOCIETY family who trade in all sessions. You can use it to trade when you need to in order to accommodate your current schedule until you can afford to use it to trade when you want to. We have heard from other traders that the same market behavior is seen in the Futures and Commodities markets, but we have not used this method to trade those markets ourselves.
This method works on all time compressions.

Some traders learn the method in just a few weeks to a few months. Most traders take 6 months to a year to really learn it. It's really about how committed you are to learning.
Mostly the London, but also the U.S. session on occasion. Many of our top traders trade the U.S. session only, but you should trade the hours that fit into your schedule.

There are web-based MT4 platforms for a fee (you must find these yourself via the internet.
