One way I avoid bias is to not look at charts above my time frames. It's not that I don't have an academic interest in where the market may go but I make my money by taking my signals and trading my rules. I don't make any money by trying to tell the future.
Posting trades is mostly for the poster and maybe a little for reader. It allows accountability to yourself and a little bit for the reader. It also helps smooth out the emotions involved in trading.
I like to see posted trades to see what others are thinking. But I never let it influence my position. Even the guys I know from here for 10+ years are wrong 30% of the time. Spooztop probably aligns closest with my trading style so if we are on the same thought then it usually pays well. In the end if you are not a lone wolf then you will not succeed long term in trading.
Folks, unless we sell off in the last 20 minutes------we have a medium term bottom in place now, ---Fully constructed.
