Which of the following is NOT one of the common entry variables in trading patterns?

In the context of trading patterns, common entry variables are typically characterized by their directional context relative to the price action and the established support or resistance levels. "Entry from above" and "Entry from below" are terms that describe traders entering positions when the price reaches certain levels—either breaking through a resistance or bouncing off a support level. These are essential strategies in technical analysis for identifying potential trading opportunities.

On the other hand, "Entry from the side" is not a recognized term in standard trading methodology. Trading strategies are largely reliant on analyzing price movements in a more linear fashion—either entering when prices are breaking out (from above or below) or reflecting price retracements at key levels. Since "Entry from the side" does not denote a common, actionable approach or clear market condition in technical analysis, it stands out as the variable that does not fit within established trading patterns.

“Upward exit” also does not refer to a typical entry variable, but rather it describes a position closure strategy. However, in the context of the question, the focus is primarily on entry variables, making "Entry from the side" the most fitting choice as a variable that is NOT commonly recognized in trading patterns.
