Hello.
I try to calculate what value for tommorow Close will make a crossover
with line 25 (oversold level) or line 75 (overbought level). Can
somebody help me?
Thanks.
RSI Formula
A technical analysis indicator that compares the days that a stock finishes
up against when it finishes lower. The RSI ranges from 0 to 100, but a stock
is considered overbought if it reaches 70 (or 80 in true bull markets),
indicating that you should consider selling the stock.
plz dend me good formula

The maths is a bit involved to show you how to calculate it, but
here's a function that does the job:
Function NextRSI(bar, period, nextClose, nrsi)
{
if (bar = period+1) {
clb = Close[bar];
if (clb == Close[bar-1])
Close[bar] = Close[bar] + 0.0001; // To avoid 0/0
The red and green O, C are apparently being controlled by the color selector
under preferences. Those can be changed (of course that becomes a global
change which you probably don't want) so that both O and C are the same color
but I don't think you can have individual local control with AFL
Are you saying you want the Close value at every bar that would make
the RSI 25% (or whatever) on that bar?
You could do that in a loop by calling this function for every bar,
but it might be a bit slow (make the RSI array calculation external,
so that it's not repeated at every bar).
One comment in relation to calling the function in a loop with the RSI
calculation outside the function. As the function ensures the two
consecutive close values aren't exactly the same, and this must be
done before the RSI calculation is performed, the Close array would
need to be scanned and all
Hello,
I juggle with NotePad++ and AB editor.
It's a bit heavy and sometimes I lose the last version between the
copy-past backward and forward movements.
NotePad++ is perfect except for auto-indent.
How can I auto-indent the afl code into NotePad++, as the prettyfy
function
does in AB ?
My wife had a copy of initial version of Parallels that was pretty bad and at
the time support was no better. She uninstalled Parallels and started using
BootCamp.
I understand Parallels is working fine now ... and Fusion has come unto the
seen and is also good... and would like to reconsider
Hi Louis,
What will show the smoothness of the pullback is r-squared. It tells you how
well a set of data points fits a straight line by returning a number from 0 to
1. 1 is a perfect fit. r-squared ins't built into AmiBroker, but it's simple to
add:
function RSquared(array, periods) {
Thanks Mike. That was helpful.

To get you going immediately, try changing your loop condition to the
following and see if it produces what you expect:
FirstBar = LastValue(ValueWhen(Status(firstbarinrange),
BarIndex()));
Ara,
I have used Parallels from day 1. It has improved a lot over the two
years. I consider it virtually seamless now. I have investigated
using Fusion recently, but It is not enticing me to change. It will
be a horse race between the companies. I will stick with what I have
until
Hey all,
I am looking for a way to simulate Monte Carlo back testing with Ami
Broker, any ideas are highly appreciated.
Thx

GP,
Thanks! Bar-by-bar in the backtest is what I have in mind.
This subset of code does the job:
= Year();
inwl = False;
for ( bar = 0; bar BarCount; bar++ )
{
inwl[bar] = InWatchListName( NDX_ + NumToStr( [bar], 1.0, 0 ) );
}

I suggest you pick up a book by Howard Bandy.
Chapter 22 (last chapter) covers Monte Carlo Analysis in detail and
provides AFL code you can drop right into Amibroker. Lot's of very
helpful information in the other 21 chapters as well.

I have a lot of drawn studies in a database and would like to have all
those studies copied into another database I plan to start using in
place of the original. I am trying to avoid having to redraw all those
studies and I hope there is some way to copy them to the new database.
I tried searching
Pete,
One way is to save all your local layouts to global layouts and that way all
databases can see the layouts and underlying AFL code. I tend to use Global
layouts for all my studies for this reason.
Cheers,

Ok, I spent about a half hour playing around with this and my
experiments show the global layout does not contain any drawn studies.
I have several trend lines, text boxes, arrows and a Fibonacci
Retracement on a stock I am tracking and I cannot get these studies
imported in the new database no
I'm beginning to understand how this works. From the help section

Is there a way to specify Exit at stop from AFL?
Did not see a parameter for it in SetOption() function
Thanks

Not sure what you mean by auto-indent, but if you go into
Settings-Style Configurator, select C++ in the language list, and
then add AFL to the User ext box at the bottom, Notepad++ will treat
AFL the same as C++ with the same syntax highlighting, etc.

I will like to know the list of Industries in the premium data
