Sorry not satisfied Harsh and waiting for rajendrani explanation .
Hem, harsh was right on most of the part,
But right now explaining and going into finer details will just make things complicated, but will definately give all explanation as to what that arrow means, but this needs to be going in systematic manner, slowly and steadily will explain, but need some time.
Please carry on with your trades as how you had been doing.
Thanks and regards,
rajendrani
