means trailing is a pointer to a data structur varible of CTrailingNone type.

but data structure only has 8 types:

• MqlDateTime is intended for working with date and time;
• MqlParam can send input parameters when creating a handle of the indicator using the IndicatorCreate() function;
• MqlRates is intended for manipulating the historical data, it contains information about the price, volume and spread;
• MqlBookInfo is intended for obtaining information about the Depth of Market;
• MqlTradeRequest is used for creating a trade request for trade operations;
• MqlTradeResult contains a trade server reply to a trade request, sent by OrderSend() function;
• MqlTick is designed for fast retrieval of the most requested information about current prices.

where is CTrailingNone? I thought I saw it as some class somewhere.
