I don't know about some of the others but for me I found the call pretty easy to take. The picture says that for that 270min price will close above 1.2440 with 98%. In other words, for that period price will stay above 1.2440 mostly (1). Now it also says price has only 15% of reaching 1.2520...so putting a TP there would be rather silly since there is only a 15% of that happening (2). So.....pick a target from the other values that have a good probability duh ! 1.2470 looks good with 87% (3). That's like what 30 pips no? I only got 10 though cause I had to leave but hey you could have easily gotten it during that 270min window.
EDIT : THE PIC IS NOT VALID ANYMORE. IT WAS FOR LAST NIGHT. THIS POST IS TO ILLUSTARTE ONE WAY OF READING IT
I want more brain power!
