Thank you very much for taking the time to do that. I tried to show in the picture how well it gives signals when it crosses the back over the 30/70 line in conjuntion with other indicators or even divergence/candlestick patterns (In the picture I have trend direction & force plus the second semaphore of 3.) With some Discression and good RR and I have made good pips with it this week on the AUDUSD. Its not a mechanicle system etc (remember semaphores move) however I believe the demarker will help any system.
