[amibroker] Debugging Stops/Exits (Was:Detecting Cause Of Trade EXIT...)

["Herman van den Bergen" <psytek@xxxxxxxx>]

You 
can use the AmiBroker charting capability to make debugging stops a lot 
easier. I added these statements to my Equity(1) statement in my system's code. 
It will help you understand how SetTradeDelays(), AllowSameBarExits and 
ActivateStopsImmediately effect you trading signals. Especially when debugging 
PortFolioTrading systems this may be helpful.<SPAN

You 
turn on this code by setting DigitsOn to 1 using the AA Param() button. 
Next you place this code ahead of all code in your Built-In Price Indicator, 
similarly to the above code you turn it on with the Right-Click Param() 
function.

Enable and Position 
the Digits with Param() of the price Chart. Your Price Chart should look 
like this with both DigitsOn set to 1:

Modify to your specific needs. 
Good luck,
