Buyers have yet again taken price above a low volume buy bar. Price went above the low volume bar of April 13th and those three following bars were "normal" volume days which is a strong indication that the buying is strong and we are definitely headed higher.
There might be a small correction but it is highly probable we are going to continue to put in new highs on the S&P. According to the daily chart as it is right now, 4,300 on the S&P is a reasonable price target.
