I define an edge as: 1. fearless 2. no greed 3. firmly execute the trading plan 4. no hesitation 5. confidence 6. self-trust as for what trading signal/setup or anything tip-off (like chart reading/news analysis/tape reading...)should be token to trigger a trade or hold a trade or close a trade is not an edge. if you do not have above 6 traits, you do not have an edge!
One possibility is without many long time proven Edges, we may never attain all of these: 1. fearless 2. "Optimum" greed 3. firmly execute the trading plan 4. no hesitation 5. confidence 6. self-trust
LOL! No wonder you believe Hershey's drivel! Did it ever occur to you that, just because the timestamp is a day later, I might not have read your post until then?
