The indicator displays harmonic patterns on the chart without redrawing with the minimum possible delay.
The calculation of the indicator peaks is based on the wave calculation, the advanced settings of which allow you to choose the parameters for your tradingstyle. At the opening of a candle (bar), when a new figure is formed, an arrow of the probable direction of the price movement is fixed, which
remains unchanged. The indicator recognizes the following shapes and their varieties: ABCD, Gartley (Butterfly, Crab, Bat), 3Drives, 5-0,
Batman, SHS, One2One, Camel, Triangles, WXY, Fibo, Vibrations. By default, only the ABCD and ABCD shapes are displayed in the settings.
Gartley. Many additional configurable parameters.

• ShowUpDnArrows-enable / disable the display of the arrows of the probable direction
• ArrowUpCode – code of the up arrow symbol
• ArrowDnCode – code of the down arrow symbol
• Show old history patterns-enable / disable the display of outdated shapes (patterns)
• Enable alert messages, actual if history OFF-enable / disable alerts when forming / changing shapes, relevant when
  disabled history
• Enable alert notification, actual if alert messages is enabled-enable / disable sending notifications (MQ ID) when
  formation/modification of shapes, relevant when the history is turned off
• Enable alert mail, actual if alert messages is enabled-enable / disable sending e-mail when forming / changing shapes,
  relevant when the history is turned off
• Enable alert sounds, actual if history OFF-enables / disables the sound signal when shapes are formed/changed.
  disabled history
• AlertsSoundFileName – the name of the audio file for the alarm
• Back color – background color
• Main text color – the color of the main text
• Main text font size – the font size of the main text
• PeriodLowest – period for the vertex search algorithm
• DivLLPeriod-period divider for the vertex search algorithm
• LLMethod1-Averaging method 1 for the vertex search algorithm
• LLMethod2-Averaging method 2 for the vertex search algorithm
• LLPrice1-price type 1 for the vertex search algorithm
• LLPrice2-price type 2 for the vertex search algorithm
• Triggersensitivity – the sensitivity of the anti-aliasing filter (or its minimal demagnetization when using the option in dynamic mode)
• UseDynamicSensivity-enable / disable dynamic filtering
• DynamicSensivityPeriod – the period of dynamic filtering
• DynamicSensivityMul-dynamic filtering coefficient
• UseMinSensivityFilterForDynamic-enables / disables the minimum sensitivity threshold value for dynamic filtering (the value is entered in the
  the triggersensitivity parameter)
• DrawPnts – enable / disable vertex display
• ArrowCode – the code of the simola of vertexes
• Limit points to search patterns – the number of vertices to search for shapes
