Emile thanks for the dialogue.  I was using the most basic of TA: trend-lines and chart formation (rectangle). The top trend-line only moved up 0.005 in 4.3m; by this reading one target would be 0.125 in the next 4m.  Of course, I am discussing the theory side of TA.  In reality, the target of trend-line and chart formation is very broad; your estimate and mine could have equal chances.
