CHANGES FOR VERSION 5.82.1 (as compared to 5.82.0)

• AFL Engine: fixes for stability issues in 5.81.0/5.82.0
• Filter dialog: a matching count wasn’t updated on opening the dialog. Fixed.
• Bug report window made a little bigger so at least crash address is seen when someone sends screenshot instead of text
  

CHANGES FOR VERSION 5.82.0 (as compared to 5.81.0)

• UI: Interpretation and Commentary windows now support color text (via EncodeColor), bold and italic styles (tags:  for bold,  for italic)
• UI: Notepad, Interpretation and Commentary windows use default GUI font instead of hard-coded Tahoma now
• AFL: functionality of PlotGrid() function extended
• UI: Filter dialog now displays number of matching symbols in real-time as selections are made
• AFL Editor: added 4 new snippets under “Function” category
• AFL: In 5.81.0 CategoryGetName returned nothing (void) instead of string type  when specified category did not exist. Fixed (empty string is returned now)
• AFL engine: in v5.81 access violation could occur when AFL array size was 0. Fixed.
• New Analysis: portfolio backtest processing was attempted even if there was no symbols that matched “apply to” filter. Fixed (unnecesary processing is skipped now).
• AFL: CCI function speeded up by 50%
• Inserting indicator with Param() calls into chart when currently selected symbol had no quotes caused exception. Fixed.
  

CHANGES FOR VERSION 5.81.0 (as compared to 5.80.3)

• AFL Engine: custom memory allocator does not use Microsoft runtime lib for reference tracking anymore. Result – complex formulas with lots of loops and OLE (especially low-level custom backtests) run upto 3 times faster in 32 bit and 4 times faster in 64-bit
• AFL Editor: Parameter info tip significantly enhanced – now it re-opens on typing each , (comma) and highlights current parameter to be entered.
• UI: Column setup dialog: added Mark All / Toggle All buttons
• AFL: GetFormulaPath() function added – returns full formula file path
• AFL Editor: Smart reference highlighting implemented (usage: mark a word and all references become highlighted).
• AFL Editor: Find/Replace shows a message box when reached the end of the file and offers restarting from the beginning if new “Wrap around” option is turned on.
• AFL Engine: code refactoring for reduced size and improved speed
• AFL Engine: when value of unsupported type was appended to string a crash could occur. Fixed.
• AFL Engine: when IIf was called the memory upsized from scalar to array could get freed twice (wrong). Fixed
• AFL: MACD() and Signal() functions made faster (approx 1.5-2x times)
• Analysis: Interest is added at the beginning of next bar (instead of end of current bar), to account for overnight rate. This also fixes the problem of ignoring interest in v.> 5.69
• UI: fixed yet another place where entering customization changed working dir
  

KNOWN ISSUES:

• No known.

這一版有問題，我從5.80升的，中間跳過5.81，也許5.81就有問題。用realtime plug-in時會把database清掉，自動交易就沒有歷史資料可以參考了

版大是用那一家的 data plug-in

謝謝

real time plug-in 是我自己開發的

k大或別的大大有用別的 real time plug-in 試過5.82.1嗎？因為我沒在用其他的real time plug-in，不知道有沒有差別，因為我的AB幾乎有beta就升級，配合plug-in也都沒什麼問題，所以覺得應該是AB的問題，先降版了，還好我有備份

小弟目前都是用 eSignal.dll 的 plug-in

一路升級上來都沒問題

報價都能正常使用

如果大大有需要的話，我這邊有從 AmiBroker 5.6
開始保留的版本

lwhuang

好的，感恩，5.80.3也用了一陣子了，明天開盤看看，應該是沒問題才對，若有需要再請k大幫忙

Built-in realtime plugins work fine.
Tomasz Janeczko has clearly mentioned that new beta is less forgiving to SDK coding mistakes.

Hello,

Thank you very much for your e-mail.

Plugins should work fine without changes and all functions work as before,
as long as plugin is written correctly,
i.e. you are NOT doing things that are wrong, such as:
a) writing data outside array bounds (before element[ 0 ] and after element[ size - 1] )
b) freeing memory that you did not allocate
c) freeing memory that you are returning as a result of the function
(the variable returned to AmiBroker is freed by AB)

New version may be less forgiving to mistakes listed in a) ... c)

Best regards,
Tomasz Janeczko

So I pretty much doubt that AB is the cause of the prooblem.

我想我找到問題了，因為我原來是混用x86跟x64版，載入同一個database，realtime開盤時是用x86，收盤匯入資料是用x64，以前都可以這樣混用，從這個版後開始有問題，不能這樣混。全部都用x86就沒問題了
