Numbers are used everyday within my scoop of work. Using calculations everyday makes technicals easier to understand. However, I feel statistics is undervalued when determining stock movement and needs to be used more so than technicals.
I take positions where I see a 5-10 point gain in the near term. I move quickly and cut losses fast. 7% loss is general rule. 25% gain is general target. Contrarian sometimes-Trender sometimes. Take what the market gives. Always learning.
