Hi
I recently tested a trading system but got some strange results from the WF
test. The WF process used exhaustive optimization.
An extract from the results (too large to reproduce in full) is:-

Hi
Here is the updated code as promised. It corrects several things that I believe
were errors in the original. All comments welcomed.

PS It hasn't copied across too well from Amibroker, so editing line

Hi
I am interested in this function also, but on inspection found a few things
that I believe are errors. When I applied it to a test data set it missed a few
valid highs and lows.
Looking at the code I saw that when testing for a swing High it (correctly)

Hi,
I'm trying to edit an existing AFL program, but find that when I attempt to
insert text within a line, the new text replaces the existing text, rather than
pushing it sideways.
It should be simple to change this, but I can't find the method. Any
suggestions please?

Is this more compact again?

I hope this isn't a dumb question , but I've had some very strange results with
what should be a really simple test (as per Howard Bandy's example on p78 et
seq in Intro to AB, but with different Buy & Sell signal generation).
Simple set up - Long positions only. No commissions, no stops, Buy and
Status("lastvisiblebar") returns -1. Presumably this is because the code is

Can someone please advise where the error is in the following simple code:-
fbr = Status("firstvisiblebar");
Lbr = Status("lastvisiblebar")-1;
x0 = fbr;
x1 = Lbr;
y0 = H[fbr];
y1 = L[Lbr];
Line = LineArray(x0,y0,x1,y1);
Plot(Line,"Li
Try round(sqrt(CountAll)+0.5)).

The following simple program illustrates an intriguing problem I
encountered when trying to develop a complicated trading system.
//Test Program
fast = MA(C,15);
slow = MA(C,50);
Buy = Cross(fast,slow);
Sell = Cross(slow,fast);
Buy = Flip(Buy,Sell);

Employing "Use" variables as shown below is a clever approach to
sorting out useful vs non-useful indicators, BUT am I missing
something basic here? The "OR" parts of each condition seem wrong.
Surely the code should read (e.g):-
RSIx>Ref(RSIx,-1) AND RSIUse == 1;
and similar for the other indic
Can anyone help with the following, please:-
1. I am developing an AFL to generate buy and sell signals by combining
different indicators with variable parameters (to be optimised). I
would like to generate a plot with price and one indicator in the top
pane, and the other indicators in separate

Hi,
Can you not solve the problem by (effectively) re-defining varx
within the expression i.e.
