Ok hear me out. Don't give me regurgitated BS.
I have been long for most of my trading years. You are better off not trying to short often.
I don't normally use more than one or two trendlines but it is difficult to find the top of a parabolic stock/ETF/market.. but there is always a top. The fed has the markets back until something real happens, which is election time. Election time creates uncertainty and people will sell, regardless of the outcome. Look at years past. All of these trendlines end up at one spot.
