The indicator generates a signal to
open a buy (up arrow) or sell (down arrow) order. Can
it can also be used as a signal for closing a previously opened order. For example,
the appearance of a buy signal can be considered as a signal to close an order,
previously opened for sale. The indicator works on higher and lower
timeframes. The indicator can be used in strategies based on trading
in the channel.

Minimum number of settings:

• w = 0-draws arrows.
• w = 1-draws lines instead of arrows
  (it may be necessary if there are many other elements on the graph that can
  obstruct the visibility of the arrows).
• br = 0-processes all bars, the main working mode (the mode supports the display of arrows).
• br = 20-a positive number – the
  number of the last processed bars. In this mode, only the channel lines are being built,
  the arrows are not displayed.
