Depends. I have made substantial profits on a sub-million portfolio on a pure TA algorithm over a span of a couple of years. I have never made the strategy a secret because I knew very well people are too lazy to actually implement it (and the cake is bigger than I could take). And yeah, nobody did. (That particular strategy doesn't work anymore)
