Hello,
Two things:
1. This text is leftover from some old beta (pre 4.7x) and does not apply (appologies for not removing it)
2. You have MISREAD this. This is the other way round.
It says " OLD versions will not automatically see indicators created with new versions"
So if you install NEW version, create some NEW indicators and then
MOVE BACK to OLD version then you will need to add them manually (from afl files).
But NEW version AUTOMATICALLY reads all previous indicators.
Best regards,
Tomasz Janeczko

>>
>> Note however that turning it on gives huge performance penalty

>>
>>
>> e.. Chart tree fix: Moving or renaming formula in charts tree now
> updates all paths in indicators that use this formula
>>
>>
>> CHANGES FOR VERSION 4.75.0 (as compared to 4.74.6)
>>
>> a.. New chart style (styleCloud) to be used to create "cloud"
> chart as in Ichimoku charts. Also useful for indicator charts like

>> Sample Ichimoku cloud:
>>
>> SL = ( HHV( H, 26 ) + LLV( L, 26) )/2;
>> TL = ( HHV( H, 9 ) + LLV( L, 9 ) )/2;
>> DL = Ref( C, 25 );
>> Span1 = Ref( ( SL + TL )/2, -25 );
>> Span2 = Ref( (HHV( H, 52) + LLV(L, 52))/2, -25);
>>
>>
>> Plot( C, "Price", colorBlack, styleCandle );
>> Plot( SL, "SL", colorRed, styleThick );
>> Plot( TL, "TL", colorGreen, styleThick );
>> PlotOHLC( 0, span1, span2, span2, "Cloud", colorLightOrange,
> styleCloud );
>>
>> Simple MACD cloud:
>>
>> m = MACD();
>> Plot( Signal(), "Signal", colorBlue, styleThick );
>> PlotOHLC( m,m,0,m, "MACD", IIf( m > 0, colorGreen, colorRed ),
> styleCloud );

>> Another MACD cloud (difference):
>>
>> m = MACD();
>> s = Signal();
>> Plot( s, "Signal", colorBlue);
>> Plot( m, "MACD", colorRed );
>> PlotOHLC( m,m,s,m, "MACD", IIf( m > s, colorLime,

>>
>>

>>
>> f.. AFL: new function: StaticVarRemove()
>>
>> StaticVarRemove("varname")
>> removes static variable and releases associated memory
>>

>>
>>
>> k.. Further speed improvements by rewriting chart ID lookup

>>
>>
>> l.. Chart title string is clipped so Y axis is never obscured
>>
>>
>> m.. Chart title can be automatically wrapped now
>> Use 'Parameters' window,

>> Miscellaneous->Wrap title: YES
>>
>> If you want to set it programmatically from the formula use

>> AlmostEqual( x, y, ulps = 5 )
>>
>> this is a helper function for comparing floating point numbers.It
> returns True if x and y are equal or almost equal upto defined

> equality check (==) as itleads to more reliable comparisons and less
> headache caused by IEEE floating pointacurracy issues.
>>
>> Parameters:x, y - the numbers or arrays to be compared,Ulps
> stands for "units in last place" and represents maximum relative
> error of the comparison. Since 32 bit IEEE floating point numbers
> have accurracy of 7 significant digits, 1 unit in last place(ulp)
> represents relative error of 0.00001 %. The default value of ulps
> parameter is 5 which gives roughtly 0.00005% "comparison sensitivity".
>>
>>
>> Example code:
>>
>> if( 1/3 == 0.3333333 )
>> {
>> printf("32-bit Floating point IEEE exact equality\n");
>> }
>>
>> if( AlmostEqual( 1/3, 0.3333333 ) )
>> {
>> printf("Numbers are almost equal\n");
>> }
>>
>> Thanks to Bruce Dawson for his fast routine.
>>
>>
>> f.. Optimize() function now checks if min < max, step > 0 and
> checks if parameter name is not empty
>>
>>
>> g.. Made Time&Sales case insensitive (when "case sensitive
> tickers" option is turned off")

>> AB = new ActiveXObject("Broker.Application");
>> AW = AB.ActiveWindow;
>> tabindex = AW.SelectedTab; // read selected tab
>> AW.SelectedTab = 3; //switch to tab 3
>> AW.SelectedTab = tabindex; // restore originally selected tab
>>
>>
>> k.. Fixed: Exception was generated when GetRTDataForeign was
> called with non-existing ticker

> past the last bar:
>>
>> Plot(Close,"Close",colorBlack,styleCandle);Plot(MA
> (Close,20), "Shifted MA", colorRed, styleLine, Null, Null, 10 );
>>
>> Note that shift occurs during plotting and does not affect source
> array
>>
>>
>> l.. Removed data source selection from preferences because it
> caused user confusion way too often
>>
>>
>> m.. Stock.Currency available via OLE
>>
>>
>> n.. Title variable now supports new special token {{OHLCX}} which
> is replaced at runtime by string "Open ..., Hi .... Lo ... Close
> (...%)" showing current price
>>
>> This way it is possible to implement formula that will show OHLC
> prices with number of decimal places set in the preferences.
>>
>> Example:
>>
>> SetChartOptions(0,chartShowArrows|chartShowDates);
>> _N(Title = "{{NAME}} - {{INTERVAL}} {{DATE}} {{OHLCX}}
> {{VALUES}}" );
>> Plot( C, "Close", ParamColor("Color", colorBlack ), styleNoTitle
> | ParamStyle("Style") | GetPriceStyle() );
>>
>>
>> o.. user-definable number of decimal places in chart titles
> (completed: 2005-09-09)
>> Number of decimal places displayed in default chart title is now
> user-definable inTools->Preferences->Miscellaneous"Decimal places in
> chart titles".
>>
>> Allowable values:
>> -1 - dynamic mode (number of decimal places automatically
> adjusted)
>> 0..6 - fixed number of decimal places
>>
>>
>> p.. QuoteArray resizing now uses heuristic algorithm to minimize
> memory fragmentation and increase performance
>>
>>
>> q.. atcFlagDeleteValues now highlighted properly in the AFL editor
>>
>> CHANGES FOR VERSION 4.71.1 (as compared to 4.71.0)
>>
>> a.. fixed compatibility problem with AmiQuote (due to changed
> order of OLE properties/method while AmiQuote was using old ones)
>> b.. now ASCII importer in $TICKMODE does not delete quotes older
> than oldest (first) record in the imported file, so you can safely
> import tick data from subsequent files (older first, newest later)
>> CHANGES FOR VERSION 4.71.0 (as compared to 4.70.5)
>>
>> a.. AFL: added GetCursorXPosition() and GetCursorYPosition()
> functions
>>
>> Functions return current mouse cursor position.
>> Values returned are equal to those visible in the status bar, and
> these functions require status bar to be visible. Returned values
> represent cursor position at the formula execution time (or few
> milliseconds before it) and accurracy is subject to pixel resolution
> of the screen (first cursor position is read in screen pixels
> (integer) and then converted to actual value therefore for example
> when screen resolution is 1024x768 maximum obtainable resolution in X
> direction is 0.1% and in Y direction 0.13%), also X values are snap
> to datetime of nearest data bar.
>>
>> It only makes sense to use these functions in
> indicator/interpretation code.
>>
>> Using them in AA window may yield random values.GetCursorXPosition
> () function returns X position in DateTime format (the same as used
> by DateTime() function).You can convert it to string using
> DateTimeToStr() function.GetCursorYPosition() returns Y position (as
> displayed in Y axis of the chart).
>>
>> Example:
>>
>>
>> ToolTip="X="+DateTimeToStr(GetCursorXPosition())
> +"\nY="+GetCursorYPosition();
>>
>>
>>
>> b.. AFL: added DateTimeToStr() and StrToDateTime() functions
>>
>> These functions allow to convert string to datetime format and
> vice versa.
>>
>>
>> Example:
>>
>> ToolTip="X="+DateTimeToStr(GetCursorXPosition())
> +"\nY="+GetCursorYPosition();]
>>
>> c.. Added ability to store charts as .GIF (in addition to PNG)
>>
>>
>>
>> d.. ASCII importer maximum supported line length is increased to
> 2048 characters
>>
>>
>>
>> e.. Fixed: .aflsafe files didn't get deleted automatically
>>
>>
>>
>> f.. Added N-volume bars charts and timeframe support.
>>
>> Custom N-volume bar intervals are definable (as usual) in Tools-
>>Preferences->Intraday.
>>
>> TimeFrame functions were also extended to support N-volume bars
> using new TimeFrameMode() function calling
>>
>> TimeFrameMode( 0 );
>>
>> - switches time frame functions to time-based operation (the
> default)
>>
>> TimeFrameMode( 1 );
>>
>> - switches time frame functions to N-tick operation (positive
> values passed to TimeFrameSet are treated now as N-tick)
>>
>> TimeFrameMode( 2 );
>>
>> - switches time frame functions to N-volume bar operation
> (positive values passed to TimeFrameSet are treated nowas N-volme
> bars)
>>
>> Example:
>>
>> TimeFrameMode( 2 );
>> TimeFrameSet( 50000 ); // 50'000 share bars..
>> ...do something ...
>> TimeFrameRestore();
>>
>>
>> Note: N-volume bars are somewhat weird (compression of data to N-
> volume bar may actually deliver MORE output bars - for example if one
> tick is 1000 shares and you have specified 100V bars then single tick
> will be expanded to TEN 100V bars - ten times original size)
>> TimeFrame functions are protected against array overrun and will
> not decompress beyond original array size (you will get an "Error 47.
> N-volume bar compressed data longer than base time frame").
>> Also switching main time frame to some weird N-volume bar value
> will result in limiting the output to maximum twice original data size
> (without error message).
>> You should keep that in mind and avoid using too small N-volume
> bar intervals that could lead to such condition.
>> Also due to the nature of N-volume bars the only TimeFrameSet()
> function will yield correct N-volume bar values, TimeFrameGetPrice()
> may give slightly distorted results.
>> It is also possible to use n-volume bars in TimeFrame functions
> without calling TimeFrameMode() - it is then necessary to specify n-
> volume bars as negative number offset by -1000000 (minus one million):
>>
>> TimeFrameSet( -1000000 - 2000 );
>>
>> // gives 2000V barsSimilarly formatted negative numbers will be
> reported by Interval() function when n-volume bars are selected.
>>
>>
>>
>>
>> g.. OLE: Save As PNG / GIF callable from automation
>>
>> Example script:
>>
>> AB = new ActiveXObject("Broker.Application");
>> AB.ActiveWindow.ExportImage("Test.png");
>>
>> h.. Plugin is not called when GetExtraData is used for symbol
> that has "use only local database" flag turned on, and NULL is
> returned instead of an error
>>
>>
>>
>> i.. Protected against changing application's current working
> directory by printing to file
>>
>>
>>
>> j.. Toolbar does not get wrapped when main frame window is
> resized
>>
>>
>>
>> k.. OLE: Analysis object has new method MoveWindow( x, y, width,
> height) that allows to control position and size of automatic
> analysis window
>>
>> AB = new ActiveXObject("Broker.Application");
>> AB.Analysis.MoveWindow( 10, 10, 200, 200 );
>>
>>
>> It has some restrictions on size: specified size can not
> besmaller than 10x10 pixels and can not be bigger than entire screen
> dimensions.
>> Also when "No minimum size for resizing dialogs" box in UNCHECKED
> in Tools->Prefs->Misc it won't shink AA window below default size
> necessary to fully display all controls.
>>
>>
>>
>> l.. ASCII importer: added ability to import tick data from text
> files
>>
>> ASCII importer now allows tick data files to be imported.
>>
>> Tick data files consist of several records having the same
> timestamp.This makes it impossible to use normal import mode which
> assumes different (unique) timestampsfor each data row (when same
> timestamp is found then new data overwrites old).
>>
>>
>> To turn on TICK mode you need to add manually
>>
>> $TICKMODE 1
>>
>> line to ASCII importer definition file.
>>
>>
>> $TICKMODE is a special mode of importer that allows to import
> quotes that haveduplicate time stamps.
>>
>> It makes two assumptions:
>> a) input data should come in the ascending time order (i.e. OLDER
> records first, LATEST records last)
>> b) input data should consist of entire tick history because
> importer will DELETE any existing quotes (to avoid creating multiple
> copies of the same ticks).
>>
>> Once again: Turning on
>> $TICKMODE 1
>> will DELETE ANY QUOTES that already exist in the database and
> then will import all ticks from input data file.
>> You have been warned.
>>
>>
>> For example data files like this:
>>
>>
> MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,2MOL
> ,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,11MOL,0
> ,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,40
>>
>>
>> Can be imported using the following definition file:
>>
>>
>> $FORMAT Ticker, Skip, Date_YMD, Time, Open, High, Low, Close,
> Volume
>> $SKIPLINES 1
>> $SEPARATOR ,
>> $CONT 1
>> $GROUP 255
>> $AUTOADD 1
>> $DEBUG 1
>> $TICKMODE 1
>>
>>
>> Sometimes it happens that input files have invalid timestamps
> (seconds > 59).
>>
>> For example:
>>
>>
> MOL,0,20050606,162970,16400.0000,16400.0000,16400.0000,16400.0000,2
>>
>> Please take a closer look at first line shown in this example it
> has time:16:29:70 (you see 70 seconds !)
>>
>> So I had to add a special flag to the importer that works around
> such data errors.
>>
>> It is called $ALLOW99SECONDS 1 and will convert all records with
> invalid seconds (i.e greater than 59)to 59s.
>> So record stamped 16:29:70 will be treated as 16:29:59
>>
>> Now for tick mode to work with such incorrect records you would
> need to add two lines to ASCII importer definition:
>>
>> $TICKMODE 1
>> $ALLOW99SECONDS 1
>>
