Libraries: TradeTransactions - page 9

New comment

I’m not sure whether this is a mistake on my part or whether it’s due to a new compiler directive, but I’m getting the following errors when compiling the library.

I did download the individual files from the RU section.

In any case, to resolve the compiler issues, change the following:


In ResourceData.mqh:

Replace: 

return  ( this  . Get(Data) * sizeof  ( uint  ) / sizeof  (T));

with: 

return  (RESOURCE::Get(Data) * sizeof  ( uint  ) / sizeof  (T));

and replace: 

if  ( this  .Get(Data) && (Pos < ( uint  ) this  .Get(Array)))

with: 

if  (RESOURCE::Get(Data) && (Pos < ( uint  ) this  .Get(Array)))


In TradeTransaction.mqh:

replace: 

const  uint  NewTotal = this  .Get(OnTradeTrans);

with: 

c onst  uint  NewTotal = RESOURCEDATA<ONTRADETRANSACTION>::Get(OnTradeTrans);

I did download the individual files from the RU section.

The page states that the code was updated on 21 September 2026, but I didn’t do that.

Apparently, MQ did this automatically across the entire codebase. They changed the encoding: UTF-8 → UTF-8 BOM.


The library hasn’t been updated for a long time. The compiler rules have indeed changed.
