### <summary>

|
### Constructs a displaced moving average ribbon and buys when all are lined up, liquidates when they all line down
|
|
### Ribbons are great for visualizing trends
|
|
### Signals are generated when they all line up in a paricular direction
|
|
### A buy signal is when the values of the indicators are increasing (from slowest to fastest).
|
|
### A sell signal is when the values of the indicators are decreasing (from slowest to fastest).
