//| You can use this indicator to measure when the LSMA angle is |
//| "near zero". AngleTreshold determines when the angle for the |
//| LSMA is "about zero": This is when the value is between |
//| [-AngleTreshold, AngleTreshold] (or when the histogram is red). |
//| LSMAPeriod: LSMA period |
//| AngleTreshold: The angle value is "about zero" when it is |
//| between the values [-AngleTreshold, AngleTreshold]. |
//| StartLSMAShift: The starting point to calculate the |
//| angle. This is a shift value to the left from the |
//| observation point. Should be StartEMAShift > EndEMAShift. |
//| EndLSMAShift: The ending point to calculate the |
//| angle. This is a shift value to the left from the |
//| observation point. Should be StartEMAShift > EndEMAShift. |

//| Red for down |
//| Yellow for near zero |
//| Green for up |
