CHANGE LOG

CHANGES FOR VERSION 5.72.0 (as compared to 5.71.0)

• AFL: new feature: high-performance Persistent Static variables implemented (StaticVarSet has new parameter 'persist' - if it is set to True then static variable will be stored in PersistVars.bin file when AmiBroker is closing and reloaded automatically on next startup, preventing the values of static variables between application runs)
  
  if( ParamTrigger("Set variable", "Set" ) )
{
  StaticVarSet("varx", Close, True ); // set persistent variable
}

Plot( StaticVarGet("varx"), "Persistent var", colorRed );
  
• 64-bit optimizer plugins: fixed issue in SPSO/Tribes with OptimizeSetOption not working correctly
• UI: Interpretation and Notepad windows do not flicker anymore when they are resized
• ASCII importer: added $USEONLYLOCALDB command
  If data is fed by database plugin, using the ASCII importer to add any symbol causes these newly added symbol to have "Use only local database" flag turned on.
  A new command:
  $USEONLYLOCALDB 0

  allows to turn this off (so newly added symbols have "use only local database" turned off)

  This flag does NOT affect existing symbols.

• Symbol pane full-text search is user-configurable (from options menu) and now supports searching by alias, address, country (in addition to search by symbol and full name).
  

CHANGES FOR VERSION 5.71.0 (as compared to 5.70.2)

• AFL: PlotText() now has additional parameter yoffset: PlotText( "text", x, y, color, bkcolor = colorDefault, yoffset = 0 )
  yoffset allows to specify PIXEL offset to Y coordinate which is expressed in price in PlotText calls. This provides easy method to position precisely the text based on font/letter specific characteristics
  
• AFL: PlotTextSetFont( "text", "fontname", pointsize, x, y, color, bkcolor = colorDefault, yoffset = 0 )
  Example:
  
  Plot(C, "Price", colorDefault );
x = SelectedValue( BarIndex() );
y = Close[ x ];

PlotTextSetFont("E", "Wingdings", 40, x, y, colorGreen, colorDefault, -30 );
PlotText( "C",  BarCount, Close[ BarCount - 1 ], colorRed, colorDefault, -20 ); // will use new font too
  
• ASCII importer: now company address can be imported ($ADDRESS <company address> command and new ADDRESS field in the $FORMAT command)
• ASCII importer: NULL can be specified as date in several date fields such as delisting date, dividend date,etc. This results in date being cleared (unset).
  $FORMAT TICKER,LAST_SPLIT_DATE,ADDRESS
  $AUTOADD 1
  $OVERWRITE 1
  $NOQUOTES 1
  $SEPARATOR ,

  XLNX,NULL,"This is new address"

• Charts: Y-axis grid can now be finer than 0.0001 (#125281) - upto 6 decimal digits (0.000001) are displayed when needed
• Charts: Null values in Open/Close fields now disable drawing of open/close ticks in the bar chart (PlotOHLC function)
  Plot( C, "", colorDefault, styleNoDraw );
PlotOHLC( Null, High, Low, Null, "Price", IIf( H > Ref( H, -1 ), colorGreen, colorRed ), styleBar | styleNoLabel, Null, Null, 0, 0, -100 );
  
• UI: Last pane height does not change on window resizing after pane resize anymore.
• New Analysis: in Windows 7 and 8 the progress of scan/backtest/exploration/optimization is also shown in Windows Taskbar, so it is visible even if AmiBroker window is minimized or covered by other windows
• New Analysis: Backtest report settings: added option NOT to include Formula in the report (for security purposes)
• New Analysis: Horizontal scroll bar is refreshed after HTML import
• Prefs: Currency tab, added option "Trade using FX cash conversion" to handle different ways to calculate profits depending on whenever foreign currency is borrowed or cash actualy exchanged
  
  When you actually exchange the cash when entering a trade on security traded in foreign currency then you should have this option turned ON
  when you use a loan in a foreign currency, turn this option OFF (the pre 5.71-behavior)
