Hello, I'm trying to get ticks from 54 weeks before to current time, so I get an exception and can't get moar than 20 weeks.
Why I need this? Because I need tick data to learn my neural net.
Please, what I need to do?
CODE:
public class MA_Play implements IStrategy {
...
private final int WEEKS=54;
...
@Override
public void onStart(IContext context) throws JFException {
...
/**
* GETTING TICKS.
*/
ITick tick = history.getLastTick(instrument);
long time = tick.getTime();
List<ITick> ticks = new ArrayList<>();
long TC = System.currentTimeMillis();
for(int i=WEEKS; i>=0; i--) {
//dwatchdogTimer.refresh();
DateTime beginWeek = new DateTime(time).minusWeeks(i).withDayOfWeek(DateTimeConstants.MONDAY).withTimeAtStartOfDay();
DateTime endWeek = i>0?new DateTime(time).minusWeeks(i).withDayOfWeek(DateTimeConstants.SUNDAY).withTimeAtStartOfDay():new DateTime(time);
System.out.print("Week:"+i+". Getting ticks from "+beginWeek.toString("dd.MM.yy")+" to "+endWeek.toString("dd.MM.yy"));
List<ITick> t = history.getTicks(instrument, beginWeek.getMillis(), endWeek.getMillis());
System.out.print(", size = "+t.size());
ticks.addAll(t);
System.out.println(", overall size = "+ticks.size());
if (i%20==0 && i>0) {
try {
System.out.println("Please, wait 6 min.");
Thread.sleep(1000*60*6);
} catch (InterruptedException ex) {
Logger.getLogger(MA_Play.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
System.out.println("Recieved "+ticks.size()+" ticks in "+(System.currentTimeMillis()-TC)+" ms.");
...
}
...
