A net position in trading refers to the difference between a trader’s total long (buy) and short (sell) positions in a particular asset or market. It is calculated by subtracting the total number of short positions from the total number of long positions. For example, if a trader holds 500 long positions and 300 short positions in a particular market, their net position would be 200 long positions. A positive net position indicates that a trader is more bullish on the market, while a negative net position indicates a more bearish stance.
