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.
It looks like he is just guessing, and I guess that in time he tells you about uptrend it is
probably the peak and we can be late for buying.
