RE: [amibroker] Conditional include, AmiBroker Email List Archive

Of course on the {}. I didn’t not think about the multiple lines of code. That explains another error.

One question: does LastValue() represent the LastValue as determined by the currently executing bar or is LastValue the very last value of the array, thus giving the same result every time?

I guess I can easily test this myself!

Hello,

First, you have to use BRACES, since #include simply "pastes" code from external file in the place when

it is used, so you end up with MULTIPLE lines (so they have to be enclosed in braces.

Second thing is that your newBuy and newSell are ARRAYS and can not be used in "if" condition

See MOST COMMON MISTAKES:
http://www.amibroker.com/guide/a_mistakes.html

So corrected code would look as follows:

if ( LastValue( newBuy OR newSell ) )

{

#include <W_Xfactor.afl>

}

else

tradeLevel = trange = 1;

However please note that this operates on lastvalue only, not on bar-by-bar basis.

Please read Understanding AFL

http://www.amibroker.com/guide/h_understandafl.html

to learn how AmiBroker processes array statements.

If you need bar-by-bar execution you need to write a LOOP.

Subject: [amibroker] Conditional include

I would like to conditionally load and execute an Include file only on days when certain conditions are True. I do this with ParamToggle all the time since ParamToggle creates a numeric or Boolean condition. Now I want to do it only on days when I have a Buy or Sell condition which is in an array and Amibroker complains that array is not allowed in an if() statement. IIf is not acceptable since it is just an assignment statement. I don’t want to build a loop since the include file uses arrays.

Here’s the code. Any ideas?

    if (newBuy OR newSell)

        #include <W_Xfactor.afl>

    else

        tradeLevel = trange = 1;

Error 6. Condition in IF, WHITEL, FOR statements ahs to be Numeric or Boolean type. You can not use array here, please use [] (array subscript operator) to access array elements.
