TradeLog MTM has all of the same features as TradeLog, plus additional mark-to-market accounting procedures. This section will only address the mark-to-market (MTM) procedures for beginning and ending the tax year, as these differ from the procedures found in the standard version of TradeLog (for cash accounting).
The mark-to-market tax accounting method only affects traders at year end. The term "mark to market" literally means to "mark" or price all open positions to year-end market prices. Therefore, the MTM status trader shows no open positions (on paper) at year-end because they have all been "closed" at the year-end closing price. The year-end price now becomes the MTM status trader's cost basis for their open positions going into the following tax year.
