Can't able to find Crude graph

I wanted to do technical analysis for crudeoil equity, i am unable to find crudeoil equity script, all i get is futures which has limitation of 2 months data. if i want to do long term analysis, like how it behaved last 2 years, i dont get it in future. If, I want to plot 50 ma (moving average) on crude one year chart, where can i able to plot. Or tell me how can i create chart with crude ohlc data and how to put indicators on that
Kindly guide me how to get crudeoil chart like equity.
