When Should I Avoid Trading?
The least active time to trade -- dare we call it the “cold zone” -- is the European-Asian overlap session. Most traders are sleeping (or taking a nap) during this short period. Trading volume is very thin and trends are unpredictable during this period. Stay out of the cold zone! However, this is a good time to get prepared for the opening of the European session.
The cold zone runs from 2am to 4am EST. (BD Time 1pm to 5pm)
