Overnight Adjustment
The overnight adjustment amount will be shown in the detailed report to account for the trader coming into the day with a position or taking a position overnight. The value of the overnight amount must be applied in order to compute realized p/l for that day.
Therefore, the overnight adjustment is the difference in the daily realized P/L and the total value of the position traded that day.
For example:
Day 1 Buy 100 shares XYZ @ $1 Value traded = -$100 Overnight Adjustment = $100 Realized P/L = 0 Day 2 Sell 100 shares XYZ @ $2 Value traded = $200 Overnight Adjustment = -$100 Realized P/L = $100
