Hello all,I couldn't be more pleased with all the Amibroker
improvements lately, I am still often amazed what this fantastic piece
of software is capable of.
I am going wrong somewhere with the loop sample below when changing
the expression: Close[ i ] priceatbuy * 1.2 ) into: Close[ i ]
Shouldn't you be referencing Priceatbuy[i] within the last 'if'
statement... 'if' statement are supposed to return a boolean... and
you can't get a boolean by comparing an array... and Priceatbuy is an
array...

Hello,
I am also having NEGATIVE volumes in some heavy volume securities on

Sanjiv,
It sounds like number overflow... AmiBroker divides volumes by 100 to
try and avoid this... however, if volume is huge you could still get
number overflow and end up with negatives. It's the limitations of the
variable type you are hitting, not data errors... in my view.

hi,
could you explain what you try to do? 1 error I see is that priceatbuy in the
loop also needs to be handled as an element, like priceatbuy[ i ], but then
still I can't figure out what you are trying to do,

Hi Ed, the loop is just a simple profit target stop for testing other
parts of my systems and a reference to the Entry Price.
Once changing the Close[ i ] priceatbuy * 1.2 expression and
basically making it a stop, things go wrong. Or is it my logic? LOL

There is no syntax error with your code if this is what you want to know.

That will keep volume in hundreds of shares and you won't get overflow.

Hi,
You've got two problems.
1) IIf returns arrays. So, both b and s will be arrays, not scalers.
Therefore, you cannot use the 'if' statement with them later.
2) The operator '=' actually *assigns* a value to all elements of the
array. For comparrisons, you must use the '==' operator, not
Just to follow up. The best way to capture the results of an

the File button from of the AA window.

hi,
I think that for your initial question indeed loops are required. Getting rid
of these excess buy signals can only be done once you know where the sell is in
the array. So I would think you would have to solve it like in my example code.
But maybe the master himself knows how to solve it

Tim,
you can plot vertical lines at any 'time' (x axis) on the chart that
you want... use something like,

| styleOwnScale | styleDashed, 0, 1 );
