How long would you say you find yourself holding the pincher trades before finally taking profits on average SG? I'm guessing that if the pinch occurs on the chart of a larger time frame, then you'll wait longer than if the pinch occurs on say a 5 minute chart, but is that the case all the time?
Also, I can't help but notice looking at your chart below that oftentimes the price will reverse a fair number of pips before the pinch actually presents itself at it's tightest point before the lines turn and roll over reversing from top of indi window toward bottom or vice versa, so how can you make most of the price action and pippage potential?
