RE: [amibroker] Corrupted Symbol Tree - AB 4.8 will not run - HELP!!

One database. I keep a smaller database with fewer stocks [12,000] and
less history for trading. Historical database includes extinct stocks
for proper back-testing. [As you can see there are an enormous number of
extinct stocks so if you don't test with these you will get a
substantial survivorship bias]. I have an AFL to create various
watchlists based on price, volume, US or Canadian, etc. [Thanks to b519b
for the original code.]

Do you keep all those stocks in one database? or separate databases?

 

I was wondering how you manage those files.  I assume you keep dead
symbols for backtesting?

14k tickers are a lot, duude!

I've used the method described without probs but with 8k tickers - check
the
memory requirements of Amibroker as it progesses using Task Manager.
