Проблема с методом Strategy.OnProcess()

strategyManager = new StrategyManager(Trader);
MyStrategy ms = new MyStrategy(indent, offset, volumeOrder, security);

strategyManager.Register(ms, portfolio, security);

ms.Start();

class MyStrategy : Strategy
{
public MyStrategy(int _indent, int _offset, int _volumeOrder, Security s)
: base(){......}

protected override bool OnProcess()
{
//Тут некоторые действия происходят.

return true;
}
}
