//| 1) RSI 14 period of close. Plot this as the gray line
//|
//| 2) 3-period exponential moving average of #1 above.
//|
//| 3) 3-period exponential moving average of #2 above.
//|
//| 4) 3-period exponential moving average of #3 above.
//|    Plot this as the blue line.
//|
//| 5) 5-period simple moving average of #4 above
//|    displaced 3 bars to the right.
//|    Plot this as the red line.
