Prevent "get_order_book error: 13" error (if no level II available)?

[Heart]

Is there a way to prevent the get_order_book error: 13 error if the connection doesn't support level II data?

Something like

#if MarketDataIsSupported
protected override void OnMarketDepth(MarketDepthEventArgs e)
{
 ...
}
#endif

Hello Heart,

There is not a way to prevent that error if you try to make a subscription to level 2 data by using the override. To resolve this, you will want to reach out to your broker or market data provider and let them know that you would like Level 2 market data for the instruments that you are looking at and trading.
