I wrote very simple custom indicator using external DLL. It compiles and shows up on a chart very fine. Next, I wrote EA using this custom indicator. EA also loads and works very fine. However, any attempt to test this EA in strategy tester gives this error:
2011.10.22 20:16:18 expert removed because custom indicator 'MyTestDLL' cannot load [4802]

Indicators and EA are all properly placed. DLL is placed into:
1. \Program Files\MetaTrader 5\MQL5\Libraries
2. \Program Files\MetaTrader 5\
3. \Windows\System32
System: Win 2003 Server 32 bit

DLL does not have any external dependencies except for Win kernel.

Any advise on matter will be much appreciated.

You are completely right! "tester_library" and "tester_indicator" resolved the problem. Thank you very much.
