Define "realistic." Your series is fairly autocorrelated - one may question whether it's random enough. Looking at the price picture you can see this - each day's price is largely the result of the previous day's momentum.

I agree with tmharish that you should look at real stock data for a realistic series. Google finance lets you look up historical data on a stock and exports to .csv (ex.). I'm sure there are other sources out there.
