Can't I export quotes using this code without opening a chart

New comment
 

I have a script to export quotes but it only works if I open a chart. Can't I modify so that I'm not obliged to open a chart first ?

Excerpt of source code :

FileWrite(handle, "Time;Open;High;Low;Close;Volume");

// data recording

for(int i=iBars(symbol,theperiod); i>=0; i--) {



datetime t = iTime(symbol,theperiod,i);

// int year = TimeYear(Time[i]);

int year = TimeYear(t);

if (year > 1970) {



string strdatetime = TimeToStr(t);

strdatetime = StringSetChar(strdatetime,4,'-');

strdatetime = StringSetChar(strdatetime,7,'-');

double Open_i = iOpen(symbol,theperiod,i);

double High_i = iHigh(symbol,theperiod,i);

double Low_i = iLow(symbol,theperiod,i);

double Close_i = iClose(symbol,theperiod,i);

double Volume_i = iVolume(symbol,theperiod,i);

FileWrite(handle, strdatetime, Open_i, High_i, Low_i, Close_i, Volume_i);

}

}

FileClose(handle);

Where do you think it gets the prices from?

Well I thought that Bars was for current chart and iBars( string symbol, int timeframe) wouldn't need any chart since symbol and timeframe have been given.

I think it is ok, the symbol, theperiod parameters are not taken from the opened chart, can be anything. From one chart you can access all other existing chart and timeframe data.

I think the problem is that the chart is the only "interface" for running a task (script), an opened chart is needed for tasks that do not even require any chart.

 
  1. It's ok, as long as you handle 4066
  2. Scripts run on a chart. The OP wanted one to run with no chart. Thus my original comment.
