    getHistoricalData() returns incorrect candle data. Problem is in parseHistorical() function on line number 1032. 
    function parseHistorical(jsonData, headers) {
    		// Return if its an error
    		if (jsonData.error_type) return jsonData;

    		var results = [];
    		for(var i=0; i<jsonData.data.candles.length - 1; i++) { //should not be length-1 
                   // for(var i=0; i<jsonData.data.candles.length ; i++) {  Correct one
    			var d = jsonData.data.candles[i];
    			results.push({
    				"date": new Date(d[0]),
    				"open": d[1],
    				"high": d[2],
    				"low": d[3],
    				"close": d[4],
    				"volume": d[5]
    			});
    		}

    		return { "data": results };
