fish: The 24th was the least strong hammer we could have. The lower shadow (some call it a wick) needs to be at least twice the size of the real body (difference between open and close) for a hammer formation. This one is almost exactly 2X the size (real body 9 cents, lower shadow 19 cents). That being said, the candle on the 25th is in no way confirmation of an up move. The 25th candle is an "inside day", that means INDECISION. It would have been a confirmation signal to have an open on the 25th equal to (or slightly lower than) the 24th with a higher close and little-to-no upper shadow. The only real signal here seems to be sideways price movement. All IMO, obviously.
