### <summary>
|
|
### Demonstration algorithm showing how to easily convert an old algorithm into the framework.
|
|
###
|
|
### 1. When making orders, also create insights for the correct direction (up/down/flat), can also set insight prediction period/magnitude/direction
|
|
### 2. Emit insights before placing any trades
|
|
### 3. Profit :)
