It is described here:
https://manual.zorro-project.com/brokerplugin.htm

Some knowledge of C structs and memory management would be helpful in using the function.

Yes,

this I read but:

Code

function run()
{
    assetList("Assets4");
    LookBack = 0;
    BarPeriod = 1;
    
    T6 mData;
    char symbol[7];
    
    strcpy(symbol,"EUR/USD");
    int n=BrokerHistory2 (symbol, 1600326000, 1600326000, 1, mData);

get this error

mt4Data compiling.......
Error in 'line 169:

< int n=BrokerHistory2 (symbol, 1600326000, 1600326000, 1, mData); >.

Ah, it looks like Zorro did not expose the function to Zorro scripts. You'd have to manually load the DLL file and set up a function prototype, etc etc.

It's been done before:
