No-trades-with-Max-risk-sizing

I am not see trades in my backtest using max risk % sizing. I have overridden GetMaxRiskStopLevel like this:

CODE:
public override double GetMaxRiskStopLevel(BarHistory bars, PositionType pt, int idx)
      {
         // Compute from the close using side-specific percent
         double referencePrice = bars.Close[idx];
         double referenceStopPercent = (pt == PositionType.Long) ? mLongStopPercent : mShortStopPercent;
         double frac = referenceStopPercent / 100.0; // convert percent → fraction
         double offset = referencePrice * frac;
         double stop = (pt == PositionType.Long) ? (referencePrice - offset) : (referencePrice + offset);
         
         
         return stop;
      }

I have printed the stop levels (code not shown) to the debug log, and the levels look reasonable but I get no trades. I know that the strategy generates trades because if I use % of equity all my expected trades show up.
