Hello,

First please check if ANY trades were entered - if not - it is most probably to insufficient funds and/or wrong settings.
If they were: zeros and N/A may appear if for example there were no losing or no profitable trades.
Some stats/metrics involve dividing the values by number of trades (winning or losing) and if there is no such trade
in your backtest you will get N/A. N/A is simply place holder of "division by zero".

Best regards,
