// TradeStation does not allow the user to make a Multi Data Chart with 
// a Tick Bar Chart and any other type a chart. This indicator allows the 
// user to plot a daily 3-10 Oscillator on a Tick Bar Chart or any intraday interval.
// Walter Bressert's 3-10 Oscillator is a detrending oscillator derived 
// from subtracting a 10 day moving average from a 3 day moving average. 
// The second plot is an 16 day simple moving average of the 3-10 Oscillator. 
// The 16 period moving average is the slow line and the 3/10 oscillator is 
// the fast line.
// For more information on the 3-10 Oscillator see Walter Bressert's book 
// "The Power of Oscillator/Cycle Combinations"
