to be honest i ever use this kind of service a while ago and end up stopping it, because it'll only benefiting the programmer,
a simple logic from my view about this thing so called signal,
the programmer use some source or code and make it into a program that can read the movement.
afterward they will only find a way to see it from their perspective,
for example if the programmer using fibonaci in his trading life,the program will run that forever and it's not efficient because the movement will not exactly same like before.
i think it would be better for you to start your own technical analysis and make your own signal other than believing someone who you do not know.
