As pointed out in a comment to this series, the Interpretation Window can be a valid alternative to using DebugView. A few points to consider when choosing either method are listed below. <\/p>\n
Debug information is routed to DebugView using this type of statement: <\/p>\n
<\/span><<\/span>p<\/span>><\/span>DBVOn <\/span>= <\/span>ParamToggle<\/span>(<\/span>"DebugView"<\/span>,<\/span>"OFF|ON"<\/span>,<\/span>0<\/span>); <\/span>\/\/ Controls all output <p>if( DBVOn ) _TRACE(\"# BuyPrice =\"+NumToStr(BuyPrice,1.2)); <\/span><\/pre>\nAny type of information that can be expressed in string format can be send to DebugView. A few DebugView features are: <\/p>\n
– A stand-alone program
\n– Display accumulates multi-pass information
\n– Output includes timing information
\n– Output can be manually or auto saved to a file
\n– Optional scrolling display
\n– Copy and paste to\/from clipboard
\n– History depth setting (#lines displayed)
\n– Filter\/Highlight wrt keywords
\n– Always on top
\n– Find
\n– Software Clear display
\n– Low overhead (depending on the number of _TRACE() statements used) <\/p>\n
Interpretation Window<\/h3>\n
Debug information is routed to the Interpretation Window using this type of statement: <\/p>\n
<\/span><<\/span>p<\/span>><\/span>BuyPrice <\/span>= <\/span>LastValue<\/span>(<\/span>C<\/span>); <<\/span>p<\/span>>if(<\/span>Status<\/span>(<\/span>"Action"<\/span>) == <\/span>actionCommentary<\/span>) \r<<\/span>p<\/span>>{ \r<<\/span>p<\/span>><\/span>\/\/ This code executes only when the Interpretation Window is open. \r<\/span><<\/span>p<\/span>><\/span>printf<\/span>(<\/span>"Buy=%1.2f\\n"<\/span>, <\/span>BuyPrice<\/span>); \r<<\/span>p<\/span>>} <\/span><\/pre>\nSome features offered by the Interpretation Window:<\/p>\n
– The Interpretation Window is optimized for Chart-Commentaries
\n– Only displays info for current pass
\n– No history
\n– Copy and paste to clipboard
\n– An open Interpretation Window adds one full execution cycle to the code. <\/p>\n
While not all pros and cons were covered it can be seen from the above listing that DebugView is designed for debugging while the Interpretation Window is not. <\/p>\n
When running complex real-time trading systems the additional pass through the AFL code may prove to be too costly in terms of execution speed. <\/p>\n
