2020.08.06 11:46 1,31719 1,31723 1,31692 1,31698 0 92,73333

- I have all M1 data in the MT4 for this symbol

I trying many way, how to repare this:
a) delete file symbol.t6 and run script download.c / working
b) run script without delete file and run script download.c / not working
c) run script withoud delete with and run script download.c with option OVERRIDE / not working

version 2.30 - if running the trade AOS - not save new candle into symbol.t6 ( 2.32 also not )

I trying found any SW function ( I not happy with this )

I have a Idea:

bool checkHistory(){

// becouse I not found the fce how to add new data in the middle symbol.t6
// load data into dataset
loadMaster(); // work OK

loadMissingData(). // prepare second dataset

mergeData(dts1,dts2)

// save complete dataset
saveData(dst,symbol.t6)

return true;
}

Code

bool loadMaster(string InName){
    masterRec = dataLoad(MASTER,InName,7);
    if(!masterRec) { printf("\nCan't open %s",InName); return false; }
    printf("\n%i bars",masterRec);
    return true;
}

Is a correct way? I exist any simplest solution?

update 2020/09/17:
+ load data from t6 working
- still I cannot found how to download exact M1 bar from the MT4

ee this

zorro code:

Code

    var dSend[10];
    dSend[0]=1;
    dSend[1]=1600326000;
    dSend[2]=1600326060;
    dSend[3]=1;
    brokerCommand(3001,dSend);

and this is I know, how to read in MT4

Code

         	switch(command) {
                case GET_HISTORY:
                    Print("Command ",command,": ",arr[1]," ",arr[2]," ",arr[3]);
                    arr[0]=0.0;
                    arr[1]=1.0;
                    arr[2]=2.0;
                    arr[3]=3.0;
                    respond(cmd,arr,4);   
                    break;
           ....

but I don't know, how to get returned data / respond(cmd,arr,4) / in zorro

First M1 candle: (4) = 7:0 (20-01-02 07:00)
GAP: (4) = 48:47 (20-01-02 21:48)
Master (252776): (4) = 21:49 (20-01-02 21:49)
Master (252777): (4) = 21:48 (20-01-02 21:48) < -- 21:47 mis
Master (252778): (4) = 21:46 (20-01-02 21:46)
Master (252779): (4) = 21:45 (20-01-02 21:45)

Finish M1 candle: (4) = 21:48 (20-01-02 21:48)

thank's Milan
