- Long upper tail indicates potential bearish pressure.
- Long lower tail indicates potential bullish pressure.
- Excess on both tails indicates market indecision or high volatility.
Parameters

  The candle to evaluate for excess tails.
Returns SIGNAL_DIRECTION
A SIGNAL_DIRECTION indicating the direction of excess: - BULLISH if there's significant excess on the lower tail. - BEARISH if there's significant excess on the upper tail. - BIDIRECTIONAL if both tails exhibit significant excess. - NONE if no significant excess is detected.
