Can you please explain how the following is calculated?

Maximum drawdown: Is’t based on end of day balance or from at any time. Does the calculation is based on the booked loss or mtm loss?

No. of drawdowns:

Average “pip length” of a trade: is’t based on time like how long a trader was holding the position.

Why is total pips gained is not shown in the statistics page?

All drawdowns are calculated on the end-of-day balances, hence, you can easily see them on the rank/balance chart. The only exception is the current day. The last available equity is taken for the drawdowns calculation in that case.

The number of drawdowns is the total number of equity depreciation times during the contest period.

The average "pip length" of a trade is the result of the calculation of the Dukascopy points 3rd evaluation parameter. To find the precise calculation formula see the calculation methodology :https://www.dukascopy.com/tradercontest/?action=contestrules#methodology
