Did you mean 80.50? That's the RTH VAL a the moment.. if you meant 81.50, time to calibrate that software ;-)
same indicator which gave me clues to cover short at 80.72 . gave clues to get long 80.50. out flat 80.75. So, in the end worked out OK. I use this indicator for fast in and out.
In the end it worked out OK, i meant to say that I was feeling bad that i covered at 80.72 as price went down to 80.50. Since , it gave me long at 80.50, it turned out to be OK. above 81. it can run to 81.50
