Hi trying to set specific date ticks. I don't understand why the following code does not work
figure()
hold on
box on
plot(date1,series1,'k')
plot(date1,series2,'r--')
xlabel('Date')
ylabel('Price')
DateString = {'06/30/2010';'11/30/2010'};
datenum(DateString);
set(gca, 'XTick', datenum(DateString))
dateFormat = 1;
datetick('x', dateFormat)

datetick('x', dateFormat, 'keepticks')

Your date1 appears to be datetime objects, and you appear to be using R2016b or later. In that case you do not use datetick.
figure()
hold on
box on
plot(date1, series1, 'k')
plot(date1, series2, 'r--')
xlabel('Date')
ylabel('Price')
DateString = {'06/30/2010';'11/30/2010'};
ticlocs = datetime(DateString); %R2014b or later
ticlocs.Format = 'dd-MMM-yyyy';
set(gca, 'XTick', ticklocs); %R2016b or later

If you have access to R2016b or later, you will probably be much happier using datetime rather than datenum/datestr, including for plotting:
d = datetime(2015,1,1:500);
x1 = randn(size(d));
plot(d,x1)
ax = gca;
ax.XAxis.TickValues = datetime(2015,1,1)+calquarters(0:6);
ax.XAxis.TickLabelFormat = 'QQQ-yyyy';

Yup. For example,
ax.XAxis.TickValues = datetime(2015,1,1)+days([18 143 207 258]);
ax.XAxis.TickLabelFormat = 'MMM dd';
or
ax.XAxis.TickValues = datetime(2015,[1;5;11;14], [17;5;30;19]);
ax.XAxis.TickLabelFormat = 'yy/M/d';

In order for the TickLabelFormat to work, at least in my case, I had to specify:
ax.XTickLabelMode = 'manual';
ax.XAxis.TickLabelFormat = 'HH:mm:ss';
