So here is an example of Bernstein's MACD 9-18-1 buy signal with a postive divergence. This recent successful test of support saw a pronounced positive divergence on the MACD. So according to his buy signal you would wait for the MACD to have a breakout over the last MACD high point. (Not the price action for a buy signal.) So we'll see if this occurs. With CL being a bear I wouldn't bet my life it will go to its price resistance of 90 for that to occur.
