title: get Symbols quantmod OHLC currency data
body: <p>I am trying to retrieve the OHLC Price data for currency pairs. As you can see below I have managed to get the Close price for a defined period of time. Ideally I would also like the Open, High and Low prices too. From there I aim to analyse the data to create a forex trading system.</p>
  
  <p>Here is my work so far:</p>
  
  <pre><code>&gt; getSymbols("GBP/USD",src="oanda", from="2014-05-30", to= "2014-06-14")  
  [1] "GBPUSD"  
  Warning message:

  &gt; last(GBPUSD,4)
