I'm doing some indicator vs return statistical testing. I've been
constructing a matrix to store my counts. That's worked fine for
individual stocks & small watchlists, but is starting to encounter
issues with larger watchlists.
1) What are the size limitations on a matrix? And also size limitations
on MxToString, MxFromString and StaticVarSetText/GetText?
Most indicators have a typical range of only a couple of hundred
significant digits, but invariably some have outliers in the thousands
or tens of thousands. The fgets function mentions a 1024 character limit
before needing to concatenate - if there are similar restrictions on the
matrix<->string, matrix size or staticvar*text functions that would be
relevant to how (and when) I start worrying about outlier handling. It's
also a factor for bin sizing.
2) I've read
http://www.amibroker.com/kb/2015/10/06/how-to-run-certain-piece-of-code-only-once/
I have some code elements I don't want to run until after I've finished
making my entire matrix (i.e. after the price data for all stocks in the
watchlist has been run through & my matrix is fully formed). Is there a
(multithreaded) way to run a section of code once at the end?
Currently I'm handling it by having two explorations (one to construct &
save the matrix, then another to process, display & export the results),
but that approach feels a bit clunky.
Thanks.
