How can you possibly use "mass psychology" Hive account@jurisnaturalist. Seriously. Can you predict how the masses react? Even if you predict how the masses react, how can you then predict how the rest of the traders will react?

I can argue that charts are not any better than coin tossing.

Big banks and hedge funds do indeed manipulate the market but not based on chartism, there is no way to code visual shapes from a chart

I specified that this only applies to crypto markets.

I don't buy it for a second that it works in the long run. Swing trading often requires some insider info. This is where you battle ethics with legality.
