Chart of the day: BBY
Yesterday (2), a reversal doji-like candle signaled reversal for today (3).
Although a white heikin-ashi candle was printed today (3), it was timid, with a negative price action.
Observe that (1) corresponds to a previous reversal level in August (second pane).
As long as the heikin-ashi close remains below the average (first pane), the trend is considered bearish. The negative average (pane 2) is still negative and supports the timid reversal sign today.
As a conclusion, the reversal signs on the heikin-ashi chart (panes 1 and 2) are not reliable.
