Position Size in the Exploration

How to retrive the position size (as number of contracts) in the exploration?

For instance, I'm defining the position size based on risk as

// risk 1% of entire equity on single trade
PositionRisk = 1;
PctSize = PositionRisk * MarginDeposit / ( RiskPerContract * PointValue );
SetPositionSize( PctSize, spsPercentOfEquity );

However, in the exploration

AddColumn(PositionSize,"PosSize",1.4);

returns the percentage of equity not the number of contracts.

I would like to retrieve in the exploration the same number of contracts as I can retrieve in the detailed log in the backtest.

best,
