I could live with integers for time periods.
I believe that AB already accepts fractional numbers and
internally runs the integers.

Subject: [amibroker] Variable periods
(for CS)
I
had no problem understanding what you meant in the RSI example. However,
I think that even if we had the capability of passing variable "periods" to
functions, we would first have to convert them to integers.
Otherwise, TJ (or the function) would have to make some assumptions that
we might not like.

In
your example, the ATR could be something like 8.3. I'm suggesting
that we would need to use an Integer, Truncate, Round or
RoundUp function to make that number either 8 or 9 before passing it to
the (new) RSI function.

This
discussion started with a question about using variable number of periods for
LinRegSlope. I think most people continued the discussion about
variable periods for other functions. The discussion then grew
into other possible variables, which is fine. I, for one,
would put the emphasis on variable periods.

I clearly wrote RSI(14) vs. RSI( ATR(3) ).
The difference is the periods input.

4.31.0 BETA Question
CS,something must be more clear:Do you speak
for a variable period for RSI(periods) or for the RSI of another
function?When we write RSI(12), we mean RSI calculated on Close,
periods=12.An example of variable period should be
likeper=10+cum(1)%10;W=RSI(per);It will not work, since
built-in RSI() does not accept variable period.The second case is
to apply the RSI transformation on another function, say
Stochastics.This is already included through the RSIA(Array,periods)
function, but still for a fixed period.It would be better to be
more specific, which improvement do you ask. DT--- In
