yes there are two sides to repainting. there is undoubtedly a scam aspect where
screenshots are used to prove a near 100% win rate but the arrows have moved
from one end of the chart to the other!
but some coders are very honest that some of their indicators might expand, yet
they can still be useful as a guide, divergence as a case in point, also harmonic
trading frequently expands and then reconfigures into another mathematical
equation/pattern.
Finding an arrow that never budges and accurately predicts the future would be
the ultimate holy grail but it is never going to happen in the grown up world of trading
