USDJPY did not simply stall... it reversed direction and stopped me out. So, I compared the 15-minute chart to my one-minute configuration to see which measures at the lower level communicated what happened.I'm therefore expecting to see this pair stall for several hours before making any significant moves.
This led me right back to eight-minute price range envelopes confirmed by the 12-minute baseline, with the five-minute envelope at 0.05% deviation following rates a bit more closely. So, it appears that if I want to make money every single minute of the day, which IS what I want to do, the facts once again recommend trading primarily using one-minute charts, which is the plan for tomorrow.
However, I'm going to start practicing now using the demo platform, and learn as much as I can in the meantime.
