Hello Barry and all,
Every time the manual specifies a default value for the parameter
(as in the case of ValueWhen(): valuewhen(EXPRESSION, ARRAY, n = 1) )
it means that this parameter can be omitted (and the default value is used then).
So if you type ValueWhen( high == alltimehigh, Month() );
it means that AmiBroker uses n = 1 (the default).
As for WriteVal() function: the second parameter is for formatting
- it is a floating point number specyfying minimum number of characters
to use for output (the integer part) and the number of decimal places (fractional part).
So WriteVal( close, 9.5)
will print close price using at least 9 characters (left space-padded if necessary)
and 5 decimal places.
Best regards,
Tomasz Janeczko
