/*----------------------------------------------------------------------------------------------------
   This is one of a set of three indicators to enhance the look of your charts.
   The other indicators are: ClearView_RoundNumberMarker and ClearView_PeriodSeparator
   A template to quickly load all three is also available: ClearView_ChartTemplate.tpl

   Use these indicators instead of the default 'Show grid' from the chart properties menu.

   These indicators may be more useful for manual or hybrid trading but even
   for automated trading they could provide visual clues for optimization of the system.
   
   The idea behind the indicators is that people have a tendency to set targets and stops
   on or near round numbers (50/100/500/1000 pips) on the chart and historical highs and lows.
   As a result these price points can become support or resistance areas.
   These indicators show clearly when price is near any of these points.
   
   When loading the indicators, allow time for the terminal to update the history
   for the current chart and to retrieve data from the monthly chart.
   
   The default color sets are optimized for use on a black background.

   *  Option to have high/low for the current chart and the historical high/low for the
      currency printed upon loading the indicator

   *  Option to set historical high/low manually in case your data-provider doesn't have
      deep enough history

   *  Turn on/off bid and ask lines separately

   *  Extend bid/ask lines to the start of the chart or just to the latest bar

   *  Bid/ask lines change color when near an important price point
      (500/1000 pips, daily high/low, high/low on the chart, historical high/low)

   *  Set how many pips before important price points the color of bid/ask lines should change
      (value is set in 4-digit pips, e.g. difference between 1.30104 and 1.30204 is 10 pips)

   *  Option to have the last (5th) digit in bid/ask/spread colored differently for clarity

   *  Set the corner where to show the bid/ask/spread/time of last tick

   *  Show the bid/ask/spread/time in the main window (default) or in another subwindow of the same chart

   *  NOTE: when using ClearView_PricePointer shift the chart for better visibility
      (check the box 'Chart shift' on the 'Common' tab of the chart properties)
