Counterattack
  
Counterattack line patterns look a bit like a computer game from the '90s, but they actually somehow describe market trends.
All you need to know is that counterattack lines are a pattern chart. if the pattern is bullish, the performance of the market is trending down. If the pattern is bearish, the performance of the market is trending up.
The pattern looks different depending on a bullish or bearish market view; it looks like a candlestick pattern...but in the case of a bullish view, the first candlestick is black. In the case of a bearish view, the first candlestick is white.
