I don’t use L-II enough to give you an educated answer. I can tell you that it is common practice by mms to spike a chart off the scale with one trade way out of the time frame trade range. This blinds a technical trader on the 1 and 5 minute charts for about 30 minutes by skewing the chart data and buy/sell signals.
They do this for that reason I have no doubt.
I'm going to do some "testing" today, care to join me?
