I’m not sure I’m happy that you’ve attempted to set my position as that of someone who doesn’t think past data or any analysis. There are thousands of data points available I just rank ‘sentiment’ & ‘resistance’ in the same part of the list as planetary movements.
@bitflip said it best, the reason for taking the counterpoint in this discussion is that new investors think this is some hack to beat the markets.
The code that quants write for high-frequency traders, and continue to tweak on a daily basis, is guarded with such high security that nobody knows all the inputs. It is true that some will account for technical analysis, after all some people trade on this. It is much more likely that they’re built to front run trades, spot abnormal volumes & weight thousands of pieces of real world information.
