Low reliability Hanging Man candlestick was formed last Friday for ATN. The hanging man is a bearish reversal pattern. It signals that selling pressure is starting to increase. The long bottom shadow tells us how much the sellers are willing to sell their stocks. Although the bulls regained and pushed the price upward until the market close, the appearance of this selling pressure after a rally is a warning signal.
Note that Hanging Man is a low reliability reversal signal so we need a confirmation by form of a red candlestick, a large gap down or a lower close on the next trading day.
It would have been a bit more serious if the candlestick was red because it means that the bulls were not able to go back to the opening price.
Support levels at 2.66 and 2.54 while Resistance levels at 2.84 and 2.9
