I've diligently work through most of the instructions and rules of this noble trading system, but the only gray area for me is to fully comprehend the working principle of the semaphore.
Please Mr curioso and other knowledgeable people in this system should kindly help by pointing me to where I can learn or to kindly explain. The picture above depict some of my confusion about when a square semaphore direction is confirmed, or the continuation of the existing square semaphore with that green arrow semaphore.
Thanks, wishing you success in all your endeavours.
