Indicator Notes|$CT |Loses the 0.35 level
Definition: Previous highs and lows are commonly used key price levels. The fact that prices previously struggled to rise above or fall below these levels can often influence decisions when they reach them again.
A common interpretation: Breaking through a level only shows that one side has the upper hand for now. Whether the move can continue depends on where the next key level is and whether trading volume can be sustained.
The same reading can mean very different things in different market conditions, so don't apply any single rule of thumb blindly.
