Trading for over 12 years. Junior partner at a small hedge fund.
Came to realization that over time scalping provides a better ROI.
Asking why?
Price/market moves ONLY cause there are more buyers/sellers/supply/demand than the other side.
Technical tools are used to identify this unbalanced buy vs. sell orders. This is what actually HAPPENING now. All the rest is speculation/crystal ball/coin flip methods with no connection to what happening now.
If you able to recognize the NOW you can take advantage and have a high win probability. (Renaissance Technologies LLC - the most successful fund in the world.)
We do not think what may happened, we are not prophets. We can recognize what happening NOW. (The reason why floor traders were so successful, they were in the center of the NOW)
