Do you plot the harmonics and wait for price to come to you? As each leg of harmonics have acceptable ranges don't they. So on final leg would you have you buy area as the min/max of the acceptable range of the final leg?
Cool, and do they always come back a second time like you are expecting this one to do? As that sort of thing is what normally wrecks me when i trade harmonics... always think i've gone wrong when it come back
